AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
134 PM CST Wed Mar 4 2015

.DISCUSSION...
Strong upper trough extending from Canada down to Northern Mexico
will move east today and bring another shot of winter wx to the
region through tonight.  A mix of rain... freezing rain... sleet...
and snow is possible through tonight.  As this trough slowly pushes
east the influence of a West Coast ridge will increase and have
improving wx through the weekend into next week.

A cold front pushing through the area today will continue on to
Mexico this evening.  Cold post frontal conditions expected tomorrow
with a cold arctic airmass in place and a NE wind across the area.
Will have widespread cloud cover over the area through tonight.
Clouds will slowly decrease on Thursday.  Temps will fall through
the night as cold air advection continues with readings falling into
the 20s for nearly all the area and may see a few teens north.

A Winter Wx Advisory is in effect this afternoon through tonight for
a mix of freezing rain... sleet... or snow.  Precip has already
begun as rain and will change over to freezing rain... sleet... and
eventually mainly snow.  Freezing rain or sleet will be the main
justification for advisory as snow amounts do not look that heavy.
Heaviest snow of 1 to 2 inches possible for portions of Southeast
NM.  Snow may fall as far south as Brewster and Presidio counties.
Have expanded the Advisory southward and it now covers all the CWA
except for the Presidio Valley.  Expect the highest precip totals
tonight across the Central Permian Basin and the Lower Trans Pecos.
Currently the advisory runs through 12z but this may end up getting
extended a few hours mainly for the southern CWA if precip
continues.

Otherwise a High Wind Warning remains in effect tonight for the
Guadalupe Pass.  Will keep rest of the forecast mainly dry.  Except
for near the Rio Grande do not expect highs to get out of the 30s on
Thursday.  Another cold night Thursday night.  On Friday
temperatures begin to recover and should climb back into the 40s.
Highs in the 50s return Saturday with 60s seen by Sunday into next
week as finally get an extended amount of mild wx.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1135 AM CST Wed Mar 4 2015

.DISCUSSION...
See 18Z aviation discussion below.

&&

.AVIATION...
A cold front is moving through the area bringing increasing
northeasterly winds, colder temperatures, and lowering CIG/VIS.
VFR conditions have already or will soon decrease to LIFR at all
TAF sites. Light rain near HOB, CNM, and INK will move east and
decreasing temperatures will change the precip from rain to
freezing rain, sleet, and snow 21-03Z. Light snow will then
continue 03-12Z before ending. Some improvement in CIG/VIS can be
expected after 12Z.

.PREV DISCUSSION... /ISSUED 505 AM CST Wed Mar 4 2015/

DISCUSSION...

Another arctic cold front, and the potential for wintry
precipitation behind it, are making for a difficult forecast this
morning.  Currently, the front is located from east central New
Mexico, east/southeastward across the Texas Panhandle.  Meanwhile,
an ua trough was translating eastward over northern Mexico.  Expect
showers will continue to develop ahead of the upper system, with
perhaps a few lightning strikes from southwest Texas across the
Lower Trans Pecos through the day.  Think precipitation will remain
all liquid over the forecast area through 04/18Z despite the frontal
boundary pushing into the southeast New Mexico Plains, and Permian
Basin by then.  Winds behind the front will be at least 20 mph
sustained, and with gusts around 30 mph at times, wind chills will
likely drop into the teens.  After 04/18Z, we could see a mix of
freezing rain and sleet from SE NM, eastward across the northern
Permian Basin and western Low Rolling Plains by early afternoon,
with this mix extending into the central Permian Basin by 05/00Z.
Although ice accumulations will be limited to one tenth of an inch
or less, icy roads could develop in these areas before nightfall.
Since the low level warm layer will not be as pronounced further
west over the rest of SE NM and over the Guadalupe Mountains, expect
there to be a mix of rain, sleet and snow.  Surface temperatures
will be slower to cool in these areas, so accumulations prior to
05/00Z will not be great.  Tonight, the atmospheric column will cool
with precipitation changing to sleet and snow this evening, then all
snow after 05/06Z.  Snowfall amounts are expected to be around an
inch, perhaps two over SE NM, with an inch or less over the Permian
Basin and Western Low Rolling Plains.  A mix of freezing rain and
sleet could affect the Stockton Plateau and Lower Trans Pecos this
evening, but due to the column cooling, think any icing potential
will be fairly limited, due to a changeover to sleet or snow, and
also to how light precipitation will be in these areas.  Considering
all of the above, have decided to issue a Winter Weather Advisory
for the SE NM Plains, Permian Basin and Western Low Rolling Plains.
To keep the product from being too complicated, it will begin at
04/18Z and run until 05/12Z, despite the different timing for the
wintry precipitation.

Strong northeast winds will increase through Guadalupe Pass behind
the front tonight.  Since wind speeds will probably rise to 40 to 50
mph, have issued a High Wind Warning which will run from 05/00Z
until 05/15Z.  After precipitation ends late tonight, the ua trough
will shear eastward.  We will still be left with the arctic airmass
over the region, so have kept high and low temperatures a bit below
guidance considering how poorly models performed with the last arctic
airmass.  We will warm closer to normal over the weekend, then a bit
warmer early next week.  A weak ua trough is progged to head our way
via northern Mexico next week.  Have kept the forecast dry through
the extended for now due to variable solutions regarding the ua
troughs movement, and how weak it is.

AVIATION...

Mainly VFR conditions expected early this morning ahead of a strong
cold front. The front is expected to quickly push southwest to
near the Interstate 20 corridor by 15z and the Interstate 10
corridor by 17z. MVFR conditions will rapidly develop behind the
front with winds turning northeast and increasing to 15 to 25 mph
and gusty. Expecting IFR conditions in rain and fog to develop
generally 2 to 4 hours after fropa with a mixture of rain, sleet,
freezing rain and snow developing in the 20-24z Thursday TIMEFRAME.
IFR conditions are expected to continue Thursday evening in snow and
sleet. Northeast winds of 15 to 25 mph and gusty will continue
through Thursday evening.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1124 PM CST Tue Mar 3 2015

.DISCUSSION...

Please see the 04/06Z aviation forecast discussion below.

&&

.AVIATION...

Still looks like a mess in the upcoming 24 hours, but timing of
fropa and onset of precip, as well as the changeover from liquid
through freezing to frozen appear to be just a smidge more certain.
Opted for a faster (by 2-3 hr) frontal movement in the am, with
the cold front hitting the I-20 corridor around 15z and down to
the I-10 corridor by 17z. Initially, post-frontal stratus and a
sharp (and I mean sharp) windshift to the northeast with gusts
over 25kts can be expected, then rain should begin to fall as a
lift associated with a minor shortwave trough provides the
impetus. The question now becomes one of precip phase and timing.
Again, going with a faster frontal movement accelerates things
some. At KCNM and KHOB, BUFR soundings suggest a low potential of
freezing, so at these sites the cutover to SN should be in the
early evening hours. Further south, the warm nose above the
front looks to be sufficient to melt snow into rain, but the cold
layer underneath the frontal inversion shallow enough to keep rain
from freezing into IP. At KMAF, KINK, KFST, and KPEQ, a cutover to
freezing rain looks to occur around 05/00Z, then over to snow a
couple of hours later. As one might expect, cigs and vsbys will be
in the IFR to LIFR categories occasionally. Although there`s a bit
of elevated instability evident across the eastern Permian Basin
Wednesday afternoon/evening, there doesn`t appear to be sufficient
uvv in the charging layer to gin up thunder.

All things are subject to change.  Stay tuned.

.DISCUSSION...

Please see the 04/00z aviation forecast discussion below.

&&

.AVIATION...

Have made some changes to the ongoing owing to a quicker than
expected frontal translation. The 21Z HRRR pegged the position and
motion of the cold front at 23Z -- somewhere from just south of
Dalhart to near Borger then from there to near I-40 at the OK/TX
state line. As such, expect the front to arrive a bit sooner than
previous forecast, which unfortunately means bringing in wintry
precip and IFR/LIFR conditions Wednesday morning. Hope to have
things better pinned down on the 06z TAF issuance.

.PREV DISCUSSION... /ISSUED 255 PM CST Tue Mar 3 2015/

DISCUSSION...
A strong upper trough that extends from Montana southwestward back
to the Pacific will move east and drag across Northern Mexico on the
way to the region.  The trough will pass into the area Wednesday.
After the trough passes east on Thursday a West Coast ridge will
build into the area Friday with mild wx for the area.

Have had a marginal warm up today with highs in the 50s and 60s but
that is  not going to last long.  Today should be warmest day since
Feb 25th.  A strong cold front will blow through the area tomorrow with
an arctic airmass returning to the region.  The front has good
pressure rises behind it and is quickly moving across CO and KS this
afternoon.  This front will arrive in the NE Permian Basin early
Wednesday morning and quickly pass through the area.  The wind will
be gusty out of the N/NE behind the front.  Much of the region will
reach its high temps early with readings falling through the day.
As this front pushes through the Guadalupe Pass could see high wind.
Have issued a High Wind Watch for the Guadalupe Pass Wednesday night.
Highs only make it into the 30s Thursday. Will take a few days to
recover from this latest cold air intrusion but by the weekend
highs in the 60s should return and continue into early next week.

Have another shot of precip tonight... mainly showers but could be a
few storms.  As the cold air moves in Wednesday the precip may mix
with sleet or snow by afternoon especially across Northern Permian Basin.
This precip should change over to snow Wednesday night for much of
the region.  Currently have a SPS discussing wintry precip with max
snow accumulation up to 1 inch... if the cold air arrives faster
than an advisory may be needed.  Drier conditions begin Thursday
with no additional precip through end of forecast.

Highs only make it into the 30s Thursday. Will take a few days to
recover from this latest cold air intrusion but by the weekend
highs in the 60s should return and continue into early next week.

Have another shot of precip tonight... mainly showers but could be a
few storms.  As the cold air moves in Wednesday the precip may mix
with sleet or snow by afternoon especially across Northern Permian Basin.
This precip should change over to snow Wednesday night for much of
the region.  Currently have a SPS discussing wintry precip with max
snow accumulation up to 1 inch... if the cold air arrives faster
than an advisory may be needed.  Drier conditions begin Thursday
with no additional precip through end of forecast.

.DISCUSSION...
See 18Z aviation discussion below.

.AVIATION...
All locations are showing improving conditions with VFR expected
by 19Z. There is a chance for a return of low clouds and fog
tonight but models are showing VFR so confidence not high enough
to introduce into the TAFs at this time. Another strong cold front
will arrive late in this TAF period or shortly thereafter.

UPDATE...
DENSE FOG ADVISORY.

DISCUSSION...
DENSE FOG HAS BECOME WIDESPREAD ACROSS THE PERMIAN BASIN AND
SOUTHEAST NEW MEXICO PLAINS.  HAVE ISSUED A DENSE FOG ADVISORY
THROUGH 18Z BUT MAY BE ABLE TO CANCEL A LITTLE EARLY.  UPDATED
PRODUCTS ON THERE WAY.

PREV DISCUSSION... /ISSUED 428 AM CST Tue Mar 3 2015/

DISCUSSION...
A complicated forecast today including, the good riddance of an
arctic airmass, fog this morning, rain chances today and tonight,
the arrival of the next arctic airmass, wintry precipitation chances
Wednesday and Wednesday night, possible high winds through Guadalupe
Pass Wednesday night, and lastly, how long will this next arctic
airmass reside over the region?  Currently, the last vestiges of the
mentioned arctic airmass appear to be on the way out of the area as
surface pressure falls continue to mount ahead of a surface trough
developing south through eastern New Mexico early this morning.  Low
level moisture is beginning to spread back into the region on modest
southeasterly low level winds with fairly widespread fog according
to observations around the region.  Since cloud cover is pretty
thick, think the instance of dense fog, that is 1/4 mile or less
visibility, will not be widespread over the area, so will forego
issuance of a Dense Fog Advisory, for now.  Will utilize social
media for locations that may dip to very low visibility for the
time being.

An extensive fetch of mid and upper level moisture ahead of an ua
trough extending from south central Canada to northern Baja will
continue to spread over the region today, and with a shortwave
trough or two embedded, result in a few showers, but mainly over
west and northwestern parts of the area.  Despite the cloud cover,
and some precipitation chances, think we will finally realize some
milder temperatures areawide.  As the RRQ of a 170kt moves over the
region tonight, and another shortwave trough translates over the
region, we could see showers, if not a few thunderstorms overnight.
The resultant cloud cover, and increase in lower level moisture,
will likely keep low temperatures on the mild side tonight, but
unfortunately, this will not last as the next cold front will move
into the area Wednesday morning.

The said cold front will slice southwestward into the area Wednesday
morning, with a fairly stark drop in temperature behind it.  High
temperatures will occur early tomorrow over the northern Permian
Basin, with temperatures cooling back below normal all the way to
the Pecos River by Wednesday evening.  The latest models are all
over the place with the frontal timing, and since the mentioned ua
trough has not moved over the region yet, they are all over the
place with precipitation type behind the front too.  It does appear
the cold air deepens fairly rapidly behind the front.  Model
soundings, for what they`re worth, indicate a warm layer of air
around 775mb early on, but this erodes pretty quickly, especially
over the northern Permian Basin where surface temperatures drop to
freezing or below first.  Therefore, have opted to go with more of a
mix of sleet and snow than freezing rain.  The changeover looks to
occur during the day Wednesday, with mainly snow north of Interstate
20 by early evening.  The best moisture appears to be east of the
region by then, so expect snowfall amounts will be an inch or less.
Precipitation could change to sleet or snow south of Interstate 10
late tonight, but again, amounts do not appear to be great.  Will
highlight all of this in a Special Weather Statement since it
appears wintry precip amounts will not be great.  Temperatures will
begin to modify Thursday and Friday.  We`ll see how this pans out,
but there does appear to be one difference this go around, it looks
like we will have some sun as early as Thursday to aid the warmup.
Will keep the forecast dry through the extended as only a weak ua
trough is indicated west of the region during that time.  High
temperatures could be right around normal Sunday through next
Tuesday.

AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1124 PM CST Mon Mar 2 2015

.DISCUSSION...
See aviation discussion below.

&&

.AVIATION...
FG has settled in at MAF and looks to be here thru the night,
elsewhere FG/BR is slower to develop, but will eventually. As such
we have brought CIGS/VSBY down to at least IFR MAF/HOB and MVFR
elsewhere. SW winds will develop in low levels and clear out the
CIGS and VSBY mid morning, but mid clouds will hang around. Also
PROB30 -SHRA has been introduced in last 4-6hrs of fcst.

&&

.PREV DISCUSSION... /ISSUED 843 PM CST Mon Mar 2 2015/

UPDATE...
Ran a quick forecast update to increase PoPs over western zones
through 12Z where a deep plume of subtropical moisture continues
to stream over the region. Light radar echoes indicating maybe
some very light showers across these areas and to the west look to
continue overnight. IR satellite shows cooler cloud tops to the SW
of the Rio Grande moving toward these areas therefore continuing
light rain through early morning. Otherwise, the remainder of the
forecast package looks to be on track and no other changes were
needed at this time.

PREV DISCUSSION... /ISSUED 547 PM CST Mon Mar 2 2015/

DISCUSSION...
See aviation discussion below.

AVIATION...
Visible satellite show wrn edge of low clouds from CNM to PEQ to FST
are slowly lifting and may temporarily break. Meanwhile IFR CIGS are
at MAF/CNM/PEQ with MVFR vsby at MAF attm. 00Z MAF sounding shows
little change in moisture depth and seems to be little chance that
clouds will break here. Concern for the night is how low will
CIGS/VSBY go. Models have done terrible job last few days and will
continue with more of persistence forecast noting that T/Td spread
are a little greater than previous 24hrs indicating development of
lower vsby may be delayed a few hrs. Based on better established
low level w-sw flow Tue low clouds will break tmw, but after 15Z.
However it will still be mostly cloudy with IR satellite showing
extensive mid clouds. Precip will probably hold off the w thru
00Z/Wed but may not be too far from CNM/PEQ.

PREV DISCUSSION... /ISSUED 257 PM CST Mon Mar 2 2015/

DISCUSSION...
Fog and low clouds have once again held in place keeping
temperatures well below normal across the area. Fortunately most
locations have risen above freezing, and with the help of
increasing southerly flow temperatures should continue to climb
eliminating the threat for freezing fog and any ice accumulation.

I know we keep saying this, but tomorrow we should finally see a
significant warm up with temperatures reaching into the 60s.
Models suggest temperatures could be even warmer but mostly cloudy
skies may limit daytime heating. An upper level low will move east
into Mexico and combined with a right entrance jet region over
west Texas will provide enough instability for scattered showers
and isolated thunderstorms to develop Tuesday into Tuesday night.
Temperatures will be warm enough for all precipitation to remain
liquid.

Wednesday will be a different story as the next strong cold front
arrives. High temperatures will be seen east of the Pecos River
Wednesday morning and steadily fall through the afternoon and
night while highs west of the Pecos will be seen closer to their
normal diurnal time. Temperatures behind the front will quickly
fall below freezing meaning precipitation will change from rain,
to freezing rain/sleet/snow as the surface cold pool deepens and
the elevated warm layer erodes throughout the day. The best chance
for precipitation will be immediately behind the front where
isentropic lift will be greatest, then will diminish overnight as
low level lift diminishes and the upper jet moves east. The
biggest threat right now appears to be ice accumulation from
freezing rain and sleet making roads hazardous.

Thursday will be the coldest day with a slow warming trend
expected Friday into the weekend. The main forecast concern for
the weekend will be the speed of an upper ridge over the western
U.S. Current models show this feature to be slow moving which
could delay the warm southerly return flow and prolong cold
temperatures currently forecast.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1124 PM CST Mon Mar 2 2015

.DISCUSSION...
See aviation discussion below.

&&

.AVIATION...
06Z TAF issuance...
The main aviation concern for the next 24 hours continues to be low
cigs/vis affecting terminals overnight and Monday morning. Currently
looking at IFR/LIFR flight conditions at all but CNM this evening,
however CNM should drop to LIFR a bit later. Poor flight conditions
will continue through Monday morning and possibly into early
afternoon. Could see vis 1/2-1/4SM at times, particularly at
HOB/MAF/FST but for now will only carry 1-2SM attm. Initially
thought temperatures would hold above freezing overnight but HOB and
MAF are currently sitting at 32. Will hold off on including mention
of FZFG for now, but will continue to monitor trends and amend if
temps decrease further. Otherwise, conditions may finally improve at
most sites Monday afternoon.



&&

.PREV DISCUSSION... /ISSUED 843 PM CST Mon Mar 2 2015/

UPDATE...
Ran a quick forecast update to increase PoPs over western zones
through 12Z where a deep plume of subtropical moisture continues
to stream over the region. Light radar echoes indicating maybe
some very light showers across these areas and to the west look to
continue overnight. IR satellite shows cooler cloud tops to the SW
of the Rio Grande moving toward these areas therefore continuing
light rain through early morning. Otherwise, the remainder of the
forecast package looks to be on track and no other changes were
needed at this time.

PREV DISCUSSION... /ISSUED 547 PM CST Mon Mar 2 2015/

DISCUSSION...
See aviation discussion below.

AVIATION...
Visible satellite show wrn edge of low clouds from CNM to PEQ to FST
are slowly lifting and may temporarily break. Meanwhile IFR CIGS are
at MAF/CNM/PEQ with MVFR vsby at MAF attm. 00Z MAF sounding shows
little change in moisture depth and seems to be little chance that
clouds will break here. Concern for the night is how low will
CIGS/VSBY go. Models have done terrible job last few days and will
continue with more of persistence forecast noting that T/Td spread
are a little greater than previous 24hrs indicating development of
lower vsby may be delayed a few hrs. Based on better established
low level w-sw flow Tue low clouds will break tmw, but after 15Z.
However it will still be mostly cloudy with IR satellite showing
extensive mid clouds. Precip will probably hold off the w thru
00Z/Wed but may not be too far from CNM/PEQ.

PREV DISCUSSION... /ISSUED 257 PM CST Mon Mar 2 2015/

DISCUSSION...
Fog and low clouds have once again held in place keeping
temperatures well below normal across the area. Fortunately most
locations have risen above freezing, and with the help of
increasing southerly flow temperatures should continue to climb
eliminating the threat for freezing fog and any ice accumulation.

I know we keep saying this, but tomorrow we should finally see a
significant warm up with temperatures reaching into the 60s.
Models suggest temperatures could be even warmer but mostly cloudy
skies may limit daytime heating. An upper level low will move east
into Mexico and combined with a right entrance jet region over
west Texas will provide enough instability for scattered showers
and isolated thunderstorms to develop Tuesday into Tuesday night.
Temperatures will be warm enough for all precipitation to remain
liquid.

Wednesday will be a different story as the next strong cold front
arrives. High temperatures will be seen east of the Pecos River
Wednesday morning and steadily fall through the afternoon and
night while highs west of the Pecos will be seen closer to their
normal diurnal time. Temperatures behind the front will quickly
fall below freezing meaning precipitation will change from rain,
to freezing rain/sleet/snow as the surface cold pool deepens and
the elevated warm layer erodes throughout the day. The best chance
for precipitation will be immediately behind the front where
isentropic lift will be greatest, then will diminish overnight as
low level lift diminishes and the upper jet moves east. The
biggest threat right now appears to be ice accumulation from
freezing rain and sleet making roads hazardous.

Thursday will be the coldest day with a slow warming trend
expected Friday into the weekend. The main forecast concern for
the weekend will be the speed of an upper ridge over the western
U.S. Current models show this feature to be slow moving which
could delay the warm southerly return flow and prolong cold
temperatures currently forecast.

.DISCUSSION...

See 12z aviation discussion below.

.AVIATION...

Low ceilings and visibilities are expected to last through this
morning with gradual improvement around 18z.  Fog and freezing fog
are also possible this morning.  VFR conditions should return to the
area by 22z.  There is a possibility of low ceilings and
visibilities after 00z for some of the terminals.  Winds will remain
fairly light throughout the period and will become easterly then
southeasterly by 00z.

&&

.PREV DISCUSSION... /ISSUED 510 AM CST Mon Mar 2 2015/

DISCUSSION...

Pessimism and persistence rule, as much of West Texas and Southeast
New Mexico remain socked in w/stratus and fog.  Current sfc obs show
this backed up against the mtns, w/widespread FZFG over much of the
Permian Basin and Wrn Low Rolling Plains.  However, w/temps only
near freezing (as opposed to well-blo the last few days), we`ll
continue to handle these hazards in the HWO and with an SPS.  Over
the past few days, models have been way too optimistic in scattering
things out by late morning/early afternoon, yet this has not panned
out.  Although sfc flow will veer to SE later today, we`re not
betting on things improving appreciably, and so have stuck to the
lower end of guidance on temps.  Sfc winds will continue veering to
SW overnight as a sfc trough over CO moves out into the Central
Plains.  An upper trough making landfall on SoCal will begin sending
disturbances thru SW flow aloft as soon as tonight, favoring
isolated -SHRA omtns out west.

Tuesday, w/SW flow at the sfc, a downslope warming component and
decreasing clouds should allow temps to warm to above normal for the
first time in awhile.  However, some high clouds will still be
present and, w/all the precip of the past few days and saturated
soils, warming will be retarded somewhat.  Therefore, we again
prefer to stay on the lower end of guidance temps.  Meanwhile, the
west coast trough will dig down to Baja, open, and move thru Sonora
towards the region.  Ahead of this feature, a sfc trough and
shortwave will move thru West Texas Tuesday night, w/forecast
soundings showing enough moisture/instability down south for a
mention of isolated thunder.

Wednesday, winter returns as a strong cold front moves thru the
area.  The GFS is fastest, w/fropa at KMAF at around 14Z, followed
by the NAM at 18Z, and the ECMWF after.  Using a blend, temps will
drop throughout the day in the NE, w/a normal diurnal curve down by
the Rio Grande.  As the front moves SW, overrunning will commence as
winds begin to veer, w/a changeover to winter precip in the NE
beginning as soon as 18Z Wednesday.  Unfortunately, this far out,
models are in big disagreement over several factor which will
determine type/extent of the winter precip.  For one, as noted
above, models differ on timing of the front, and also on strength.
But the biggest difference is vertical saturation of the column.
The NAM soundings portray rather shallow moisture, favoring a
rain/freezing rain scenario, whereas the GFS saturates the column
deeply and well through the dendritic growth zones, favoring
sleet/snow.  This far out, we`ll not get too specific yet, as models
will/should come more in agreement as the event
nears.

Otherwise, this should taper off over the SW zones Thursday, w/a
slow warmup thru Sunday, but temps should stay blo normal in dry, NW
flow aloft.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1122 PM CST Sun Mar 1 2015

.DISCUSSION...

See 06z aviation discussion below.

&&

.AVIATION...

The main aviation concern for the next 24 hours continues to be low
cigs/vis affecting terminals overnight and Monday morning. Currently
looking at IFR/LIFR flight conditions at all but CNM this evening,
however CNM should drop to LIFR a bit later. Poor flight conditions
will continue through Monday morning and possibly into early
afternoon. Could see vis 1/2-1/4SM at times, particularly at
HOB/MAF/FST but for now will only carry 1-2SM attm. Initially
thought temperatures would hold above freezing overnight but HOB and
MAF are currently sitting at 32. Will hold off on including mention
of FZFG for now, but will continue to monitor trends and amend if
temps decrease further. Otherwise, conditions may finally improve at
most sites Monday afternoon.

&&

PREV DISCUSSION... /ISSUED 324 PM CST Sun Mar 1 2015/

DISCUSSION...
Low clouds have persisted throughout the day.  This is not
surprising considering the difficulties associated with scouring out
shallow cold air masses.  As a general rule, it is usually necessary
to see surface pressure falls north of the area along with a wind
shift to more a southeast to south component before we see
decreasing cloud cover and warming temperatures.  The computer
models usually try to move the cold air out earlier than it should,
resulting in the forecast being too warm.

Only in the last couple hours have we seen surface pressure falls
north of the area.  This is way too late in the day to be of much
help for the central and eastern portions of the CWA.  However, we
can see on visible satellite were southeast New Mexico and the Upper
Trans Pecos are seeing decreasing clouds.  These areas should see a
late afternoon warmup.  Other areas of southwest Texas have enjoyed
plenty of sunshine today with Marfa being lucky enough to warm into
the lower 70s.

This evening and overnight, we should see surface high pressure
build back into areas east of the mountains. We would expect to
see redevelopment of fog over a large area along an east of the
mountains. Locations over the north and northeast portions of the
CWA will remain below freezing overnight, so freezing fog is
included for those areas. Also, the northeast half of the Texas
Permian Basin could see some light rain or freezing rain overnight
with little if any accumulation expected. We have opted to issue an
SPS instead of going with another Winter Weather Advisory as impacts
are expected to be less than in previous days.

Monday appears to be another day similar to today.  It will take
some time to scour out the cold air, perhaps less time than today.
So while we might be a little warmer than today, we have opted to
go on the low end of temperature guidance.

As the surface ridge finally moves east of the area on Tuesday, it
is replaced in this progressive pattern with surface low pressure
over the Central Plains.  This should lead to a rather marked warmup
on Tuesday with temperatures climbing into the 60s and 70s across
the area with downslope southwest to west surface winds forecast
across the area.  We really don`t get rid of our mid level moisture
ahead of the next upper level system located just west of Baja at
that time.  Thus, we still have a shot at precipitation on Tuesday,
especially during the evening and overnight early Wednesday.  Most
unstable CAPE values Tuesday evening over southwest Texas are on the
order of 500 J/KG.  While not an overwhelming value, we can`t rule
out the possibility of a thunderstorm during that time period.

Another cold front is expected to make its way into the area on
Wednesday morning. The NAM is noticeable slower in moving this
front into area as opposed to the GFS. However, regardless of
model, we eventually seem poised for another winter weather event
on Wednesday. While not yet indicated in the forecast, it is
likely that temperatures will fall throughout the day on
Wednesday with snow possible across a good portion of the area. As
the models come closer into alignment the next couple days, it
will become more clear as to what Wednesday`s weather has to
offer.

While a gradual warmup is expected Thursday into next weekend, below
normal temperatures are still expected.  It appears that winter
still has somewhat of a hold on the area.

.AVIATION...
00Z TAF issuance...
The main aviation concern for the next 24 hours will be low cigs/vis
once again overnight into Monday morning. Generally have MVFR/IFR
flight conditions at all but CNM this evening, where brief VFR
conditions should return to MVFR by 02/06Z. Conditions will continue
to deteriorate over the next several hours and most terminals can
expect LIFR while FST and PEQ (being on the western edge of the low
level moisture) may hold at IFR. It is quite possible that conditions
will deteriorate faster than currently anticipated so will continue
to monitor trends and amend if needed. Could see vis as low as 1/4SM
at times, particularly at HOB and MAF but for now will only carry
1/2SM at these locations. Temperatures are expected to hold above
freezing overnight, therefore FZFG is not a concern. Otherwise,
conditions may finally improve to VFR at most sites Monday
afternoon.

Another night in the soup, w/sfc obs showing LIFR conditions all
terminals except KPEQ, which is IFR at the moment.  Skies were slow
to improve over the last 24 hrs, if at all, a/the models doing a
poor job handling this.  Models want to scatter things out to VFR a
little too optimistically.  W/sfc flow backing slightly over the
next 24 hours, this is doubtful.  Cigs should improve somewhat
today...but we`ll keep all terminals at least MVFR or lower.
Stratus/fog redevelops after sunset, returning conditions to

.PREV DISCUSSION... /ISSUED 514 AM CST Sun Mar 1 2015/

DISCUSSION...

Temperatures this morning are at or below freezing for most
locations across the Permian Basin and southeast New Mexico.  Skies
remain cloudy with light freezing drizzle and patchy freezing fog
across the area.  A Winter Weather Advisory continues until 9 am
this morning for the far eastern Permian Basin and Western Low
Rolling Plains.  The drizzle and fog are expected to clear out by
this afternoon.  Temperatures are expected to warm up slightly today
but will still remain well below normal with cloudy skies across at
least the eastern 2/3rds of the CWA.  The models did not handle
yesterday`s high temperatures well so went below guidance on today`s
highs for at least the eastern half of the CWA.

An upper trough is just off the coast of California with the upper
flow being westerly to southwesterly.  The upper trough will get
closer to the region allowing upper lift to increase.  Low level
moisture will also increase across the area tonight so rain chances
will increase tonight.  There is a slight chance of freezing rain
and sleet across the northern Permian Basin and portions of
southeast New Mexico tonight into Monday morning as temperatures
across this area drop to near or below freezing.  High temperatures
on Monday are expected to increase slightly from those the previous
day but will still remain cool as skies will be cloudy with a chance
of rain in the afternoon.  Temperatures will warm up significantly
on Tuesday as a surface trough develops across the area with
elevated westerly winds contributing to downslope warming.  There is
a slight chance of rain for locations generally along and west of
the Upper Trans Pecos on Tuesday.  The elongated upper trough will
be about to move over the area on Wednesday with a cold front
pushing through the area.  Temperatures will once again plummet into
the 30s and 40s for the Permian Basin and southeast New Mexico
behind the front.  Precipitation chances will increase across the
CWA on Wednesday with snow possible across the northeast Permian
Basin, rain possible further south, and thunderstorms possible
across the Big Bend area and Presidio Valley.  Precipitation amounts
on the GFS and ECMWF Wednesday afternoon look to be quite
impressive, especially along and south of the Pecos River.
Precipitation is expected to decrease in coverage and move southward
on Thursday as temperatures will be in the 30s and 40s across the
whole CWA.  Warmer and drier conditions are expected heading into
next weekend.

See 06Z Aviation Discussion below.

.AVIATION...

The main aviation concern for the next 24 hours will be low cigs/vis
likely affecting all terminals through Sunday morning as well as
FZFG affecting some locations through morning. Generally have
IFR/LIFR flight conditions across the board tonight with light
easterly winds in place. Low level moisture will remain in place
through morning with deteriorating cig/vis likely over the next
several hours. Could see vis as low as 1/4SM at times, particularly
at HOB and MAF. Dense fog with freezing temps in place in addition
to some possible -FZDZ will likely result in icing problems for both
planes and runways overnight. Have included mention of FZFG at HOB
and MAF while other terminals may remain too warm. Otherwise,
conditions are finally expected to improve to VFR Sunday afternoon.

&&

.PREV DISCUSSION... /ISSUED 611 PM CST Sat Feb 28 2015/

UPDATE...
We have updated the forecast to extend WSW for Lea County and most
the PB, except the west.

DISCUSSION...
Models are struggling hard with the cold shallow airmass and are
generally way too way warm, at least in most of the areas where
the advisory has been extended. 00Z MAF sounding indicates
saturated conditions in cold air thru 85h, with abrupt drying
above 85h. Vsby has been decreasing since 3 PM at MAF and Andrews
observation is now reporting FZDZ/FZFG with vsby 1/2SM.
Accordingly so, based mainly on persistence and short-term trends, we
decided to extended winter wx advisory in said areas.

PREV DISCUSSION... /ISSUED 546 PM CST Sat Feb 28 2015/

AVIATION...
00Z TAF issuance...
The main aviation concern for the next 24 hours will be low cigs/vis
likely affecting all terminals through much of the TAF period and
possible -FZDZ/FZFG through the morning hours. Generally have
IFR/LIFR flight conditions at all but INK and FST where conditions
have briefly improved to MVFR over the last hour or two. INK/FST
will return to IFR/LIFR respectively by 03-04Z. Low level moisture
will remain in place now through much of Sunday morning with
deteriorating cig/vis overnight. May have been too conservative with
vis and some places could see <1/2SM at times early Sunday morning.
Regardless, dense fog with freezing temps in place in addition to
some possible -FZDZ could result in icing problems for both planes
and runways overnight. For now, will keep mention of freezing precip
out of the TAF and amend if needed. Otherwise, conditions are
finally expected to improve to VFR Sunday afternoon.

PREV DISCUSSION... /ISSUED 305 PM CST Sat Feb 28 2015/

DISCUSSION...
Cold air, low clouds and areas of freezing drizzle and freezing
fog are stubbornly hanging in across mainly portions of the plains
of southeast New Mexico and west Texas. Expecting the lower clouds
to continue tonight in these areas with slowly rising temperatures
due to the surface high slowly pushing off to the east. With
residual snow cover, it still appears that temperatures will stay
at or below freezing across the extreme western low rolling plains
and extreme eastern Permian Basin. In addition forecast soundings
are indicating that moisture should remain deep enough for areas
of freezing drizzle to continue. Will continue the Winter Weather
Advisory overnight through mid Sunday morning for the aforementioned
area as a result. Further west across the central and western
Permian Basin and Lea county New Mexico temperatures will either
rise above freezing and or the moisture depth will not be enough
for significant ice accumulations. For these areas will expire the
Winter Weather Advisory at 6 pm cst, but issue a Special Weather
Statement for overnight and mention the lighter accumulations
expected.

For Sunday will lower high temperatures considerably especially
across the plains based on the new NAM and ECMWF guidance
indicating another surge of cooler air invading from the northeast.
The cooler air will continue to push southwest into the forecast
area Sunday night and Monday. Precipitation chances will increase
again as the upper level flow backs ahead of the next Pacific
system with isentropic lift developing. Surface temperatures
may be cold enough to support a chance of freezing rain
Sunday night and early Monday across the northern Permian Basin
and Lea county New Mexico. By Monday afternoon and Monday night
temperatures should be warm enough for all liquid across west
Texas and southeast New Mexico.

Precipitation chances will continue across a good chunk of
the forecast area Tuesday and Wednesday as the aforementioned
system approaches. Yet another surge of colder air is expected
by Wednesday with some light snow possible. The precipitation
could continue (some snow) into Thursday if the slower ECMWF is
correct.

Beyond next Thursday guidance handles the upper level low
differently so kept dry for now with slowly moderating
temperatures.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
611 PM CST Sat Feb 28 2015

.UPDATE...
We have updated the forecast to extend WSW for Lea County and most
the PB, except the west.

&&

.DISCUSSION...
Models are struggling hard with the cold shallow airmass and are
generally way too way warm, at least in most of the areas where
the advisory has been extended. 00Z MAF sounding indicates
saturated conditions in cold air thru 85h, with abrupt drying
above 85h. Vsby has been decreasing since 3 PM at MAF and Andrews
observation is now reporting FZDZ/FZFG with vsby 1/2SM.
Accordingly so, based mainly on persistence and short-term trends, we
decided to extended winter wx advisory in said areas.

&&

.PREV DISCUSSION... /ISSUED 546 PM CST Sat Feb 28 2015/

AVIATION...
00Z TAF issuance...
The main aviation concern for the next 24 hours will be low cigs/vis
likely affecting all terminals through much of the TAF period and
possible -FZDZ/FZFG through the morning hours. Generally have
IFR/LIFR flight conditions at all but INK and FST where conditions
have briefly improved to MVFR over the last hour or two. INK/FST
will return to IFR/LIFR respectively by 03-04Z. Low level moisture
will remain in place now through much of Sunday morning with
deteriorating cig/vis overnight. May have been too conservative with
vis and some places could see <1/2SM at times early Sunday morning.
Regardless, dense fog with freezing temps in place in addition to
some possible -FZDZ could result in icing problems for both planes
and runways overnight. For now, will keep mention of freezing precip
out of the TAF and amend if needed. Otherwise, conditions are
finally expected to improve to VFR Sunday afternoon.

PREV DISCUSSION... /ISSUED 305 PM CST Sat Feb 28 2015/

DISCUSSION...
Cold air, low clouds and areas of freezing drizzle and freezing
fog are stubbornly hanging in across mainly portions of the plains
of southeast New Mexico and west Texas. Expecting the lower clouds
to continue tonight in these areas with slowly rising temperatures
due to the surface high slowly pushing off to the east. With
residual snow cover, it still appears that temperatures will stay
at or below freezing across the extreme western low rolling plains
and extreme eastern Permian Basin. In addition forecast soundings
are indicating that moisture should remain deep enough for areas
of freezing drizzle to continue. Will continue the Winter Weather
Advisory overnight through mid Sunday morning for the aforementioned
area as a result. Further west across the central and western
Permian Basin and Lea county New Mexico temperatures will either
rise above freezing and or the moisture depth will not be enough
for significant ice accumulations. For these areas will expire the
Winter Weather Advisory at 6 pm cst, but issue a Special Weather
Statement for overnight and mention the lighter accumulations
expected.

932 AM CST Sat Feb 28 2015

.UPDATE...

Updating the forecast to lower high temperatures back into the
20`s and 30`s for most areas this afternoon. Clouds and heavy
freezing drizzle look to hang on most of the day for the Permian
Basin and SE NM which should keep temps from moving too much. Will
also extend the Winter Weather Advisory until 6 PM CST as travel
condition will continue to be hazardous.

&&

.PREV DISCUSSION... /ISSUED 458 AM CST Sat Feb 28 2015/

DISCUSSION...

See 12Z Aviation Discussion below.

AVIATION...

Current sfc obs show stratus and fog socked in this AM, w/all
terminals under IFR and VLIFR conditions.  Area radars show heavier
precip remains north of the area...in the form of snow...whereas
closer to home...clouds are not cold enough.  Instead, a walk
outside confirms a freezing mizzle that radar is not picking up.
Models bring this to an end by 18Z, w/skies scattering out to VFR in
the 18-22Z time frame as sfc flow veers to SE.  However,
redevelopment is likely again overnight.  Buffer soundings try to
develop VLIFR cigs, but this is likely too pessimistic, and we`ll go
no lower than LIFR attm.

PREV DISCUSSION... /ISSUED 450 AM CST Sat Feb 28 2015/

DISCUSSION...

Temperatures in the teens and twenties are across the area this
morning under cloudy skies.  Wintry precipitation is to the north of
the CWA and appears like it will remain to the north of the area.
There is a chance for freezing drizzle and fog this morning across
the area so a Winter Weather Advisory remains in effect through this
morning for southeast New Mexico, the Permian Basin, the Guadalupe
and Davis Mountains, and the Trans Pecos area.  Areas of drizzle and
freezing drizzle will remain possible across the far eastern CWA
through tonight.  Temperatures are expected to warm up today as 850
mb temperatures warm but temperatures will still remain well below
normal values.

An upper trough will begin developing just off the coast of
California by Sunday with the upper flow becoming westerly to
southwesterly.  Temperatures on Sunday are expected to warm up to
near normal values as 850 mb temperatures warm and the clouds
decrease in coverage.  On Monday, the upper trough will move closer
to the region increasing upper lift over the area.  Showers may
develop starting Sunday night as a result of the increase in lift.
High temperatures on Monday are not expected to be quite as warm due
to an increase in cloud cover and cooler temperatures aloft.
Temperatures will warm up on Tuesday as a surface trough develops
across the area with elevated westerly winds contributing to
downslope warming.  There is a slight chance of rain across the
Guadalupe Mountains and the Van Horn area as the upper trough gets
closer to the region.  The upper trough will begin passing over the
area on Wednesday with a slight chance of showers and isolated
thunderstorms beginning Tuesday night.  The models are showing a
cold front associated with the upper trough moving into the area on
Wednesday.  Temperatures are expected to cool to below normal
Wednesday and Thursday behind the front before gradually warming
back up on Friday.  There is a slight chance of snow developing
Wednesday night behind the front across parts of southeast New
Mexico, the northwest Permian Basin, and into the Guadalupe
Mountains.

southwesterly.  Temperatures on Sunday are expected to warm up to
near normal values as 850 mb temperatures warm and the clouds
decrease in coverage.  On Monday, the upper trough will move closer
to the region increasing upper lift over the area.  Showers may
develop starting Sunday night as a result of the increase in lift.
High temperatures on Monday are not expected to be quite as warm due
to an increase in cloud cover and cooler temperatures aloft.
Temperatures will warm up on Tuesday as a surface trough develops
across the area with elevated westerly winds contributing to
downslope warming.  There is a slight chance of rain across the
Guadalupe Mountains and the Van Horn area as the upper trough gets
closer to the region.  The upper trough will begin passing over the
area on Wednesday with a slight chance of showers and isolated
thunderstorms beginning Tuesday night.  The models are showing a
cold front associated with the upper trough moving into the area on
Wednesday.  Temperatures are expected to cool to below normal
Wednesday and Thursday behind the front before gradually warming
back up on Friday.  There is a slight chance of snow developing
Wednesday night behind the front across parts of southeast New
Mexico, the northwest Permian Basin, and into the Guadalupe
Mountains.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1121 PM CST Fri Feb 27 2015

.DISCUSSION...

See 06Z Aviation Discussion below.

&&

.AVIATION...

The main aviation concern for the next 24 hours will be low cigs/vis
likely affecting all terminals through much of the TAF period with
-FZDZ through early morning. Generally have IFR/LIFR flight
conditions at all but CNM where MVFR continues this evening however
this should be short-lived and CNM is expected to join the others
soon. Although non of the surface obs around the region are
currently reporting -FZDZ, local radar suggests otherwise. Will
continue mention of at least periods of -FZDZ through at least
mid/late morning Saturday which will likely result in slick runways
during this time. Will continue to monitor current trends and
amend if/when needed. Otherwise, conditions will improve to MVFR and
eventually VFR Saturday afternoon. E winds around 12kt tonight will
veer to the SE Saturday morning and become somewhat gusty at FST.

&&

.PREV DISCUSSION... /ISSUED 737 PM CST Fri Feb 27 2015/

UPDATE...
Overnight lows have been lowered generally from mountains
eastward. Sleet removed all areas. Areas of freezing drizzle and
fog have been expanded to include mountain areas.

DISCUSSION...
The 00Z sounding showed boundary layer running somewhat cooler
than NAM BUFR soundings forecast at MAF. Surface temperatures have
also failed to warm up late this afternoon, leaving actual
temperatures below the overnight lows previously forecast across
much of the area. Though warm air advection will increase
overnight with a modest low level jet, warmer temperatures aloft
will have trouble mixing down to the surface. Expecting temperatures
to hold nearly stead through evening or possibly dropping slightly
followed by a slight warm up after midnight. Also appears that
sleet is not likely with no instability or source of significant
lift.

PREV DISCUSSION... /ISSUED 551 PM CST FRI FEB 27 2015/

AVIATION...
00Z TAF ISSUANCE... THE MAIN AVIATION CONCERN FOR THE NEXT 24
HOURS WILL BE LOW CIGS/VIS LIKELY AFFECTING ALL TERMINALS THROUGH
MUCH OF THE TAF PERIOD. CURRENTLY HAVE MVFR/IFR FLIGHT CONDITIONS
AT ALL BUT FST WHERE LIFR CONTINUES THIS EVENING. LOOKS AS THOUGH
CONDITIONS WILL DETERIORATE QUICKLY OVER THE NEXT SEVERAL HOURS
WITH -FZDZ AND LIFR CIGS/VIS EXPECTED AT MOST TERMINALS BY 28/06Z.
EXPECT PERIODS OF -FZDZ TO PERSIST THROUGH SATURDAY MORNING,
POTENTIALLY RESULTING IN SLICK RUNWAYS DURING THIS TIME AS TEMPS
REMAIN WELL BELOW FREEZING THROUGH MID-DAY. WILL CONTINUE TO
MONITOR CURRENT TRENDS AND AMEND IF/WHEN NEEDED. OTHERWISE,
CONDITIONS WILL IMPROVE TO MVFR AND EVENTUALLY VFR SATURDAY
AFTERNOON. E WINDS AROUND 12KT WILL REMAIN ELEVATED OVERNIGHT AND
VEER TO THE SE SATURDAY MORNING.

DISCUSSION...
SIGNIFICANT SNOWS THAT AFFECTED OUR AREA OVERNIGHT AND THIS MORNING
HAVE MOVED EAST OF THE AREA.  HOWEVER, RADAR AND HOURLY OBSERVATIONS
CONTINUE TO INDICATE OCCASIONAL LIGHT SNOW AT VARIOUS LOCATIONS.

ROAD CONDITIONS WERE CERTAINLY AFFECTED EARLIER TODAY BY SIGNIFICANT
SNOWFALL COMBINED WITH SOME LIGHT FREEZING PRECIPITATION. THE MOST
SIGNIFICANT SNOWS FELL IN NORTHERN PORTIONS OF LEA COUNTY WHERE 4 TO
6 INCHES OF SNOW FELL. THE NORTHERN PORTIONS OF THE TEXAS PERMIAN
BASIN REPORTED SNOWFALL AMOUNTS GENERALLY IN THE 1-3 INCH RANGE
OVERNIGHT AND THIS MORNING.

EVEN WITH THE MAJORITY OF THE SNOW MOVING EAST OF THE AREA, THE
FORECAST THIS EVENING INTO THE TOMORROW MORNING REMAINS QUITE
DIFFICULT.  BOTH THE CANADIAN AND NAM MODELS SHOW VERY LIGHT
PRECIPITATION ACROSS A LARGE PORTIONS OF THE CWA, GENERALLY ALONG
AND EAST OF THE MOUNTAINS, THIS EVENING AND THEN CONTINUING INTO
SATURDAY MORNING.  THE GFS ALSO INDICATES OVERNIGHT PRECIPITATION,
PRIMARILY OVER THE NORTHERN PORTIONS OF THE CWA.  HOWEVER, THE GFS
IS HAVING SOME REAL STRUGGLES HANDLING THIS WINTER WEATHER EVENT.
THUS, HAVE TRENDED OUR FORECAST TOWARDS THE NAM AND CANADIAN MODELS.

A WARM LATER AROUND 750 MB IS EXPECTED TO DEVELOP LATER THIS EVENING
AND OVERNIGHT.  AS THIS OCCURS, WE WILL SEE A TRANSITION FROM LIGHT
SNOW TO LIGHT FREEZING DRIZZLE.  IN ADDITION, AREAS OF FREEZING FOG
ARE EXPECTED TO DEVELOP ALONG AND EAST OF THE MOUNTAINS AS WELL.

THIS SETS UP FOR AN INTERESTING SITUATION.  WHILE WE ARE NOT
ANTICIPATING SIGNIFICANT ACCUMULATIONS OF ICE, THERE IS CERTAINLY
POTENTIAL FOR MINOR ICE ACCUMULATIONS THAT WILL AFFECT BRIDGES AND
OVERPASSES.  IN ADDITION, THE LOSS OF SUN ANGLE WILL REFREEZE SOME
WET ROADWAYS ACROSS THE AREA.  THUS, WHILE NOT MEETING FORMAL
THRESHOLDS FOR A WINTER WEATHER ADVISORY, WE BELIEVE THE IMPACT
WARRANTS ISSUANCE OF A WINTER WEATHER ADVISORY BEGINNING LATER THIS
EVENING AND CONTINUING UNTIL NOON CST TOMORROW.

WE SHOULD FINALLY SEE A WARMUP BEGINNING LATE TOMORROW AFTERNOON AS
WE FINALLY WARM ABOVE FREEZING INTO THE 40S.  SUNDAY TEMPERATURES
SHOULD BE MUCH MORE IN LINE WITH CLIMATOLOGICAL NORMALS WITH HIGHS
IN THE 60S.

A WEAK COLD FRONT WILL PUSH INTO THE AREA ON MONDAY WITH ANOTHER
REINFORCEMENT OF COLDER AIR ON WEDNESDAY.  EVEN WITH COOLER AIR
MOVING INTO THE AREA, IT WILL NOT BE NEAR AS COLD AS WHAT WE ARE
EXPERIENCING NOW.  FOR NOW, WILL MAINTAIN SLIGHT TO CHANCE POPS
ACROSS THE CENTRAL AND EASTERN PORTIONS OF THE CWA THROUGH
MID-WEEK.

.AVIATION...
06Z TAF issuance...
The main aviation concern for the next 24 hours will be low cigs/vis
likely affecting all terminals through much of the TAF period.
Currently have MVFR/IFR flight conditions at all but FST where LIFR
continues this evening. Looks as though conditions will deteriorate
quickly over the next several hours with -FZDZ and LIFR cigs/vis
expected at most terminals by 28/06Z. Expect periods of -FZDZ to
persist through Saturday morning, potentially resulting in slick
runways during this time as temps remain well below freezing through
mid-day. Will continue to monitor current trends and amend if/when
needed. Otherwise, conditions will improve to MVFR and eventually
VFR Saturday afternoon. E winds around 12kt will remain elevated
overnight and veer to the SE Saturday morning.

.PREV DISCUSSION... /ISSUED 337 PM CST Fri Feb 27 2015/

DISCUSSION...
Significant snows that affected our area overnight and this morning
have moved east of the area.  However, radar and hourly observations
continue to indicate occasional light snow at various locations.

Road conditions were certainly affected earlier today by significant
snowfall combined with some light freezing precipitation. The most
significant snows fell in northern portions of Lea County where 4 to
6 inches of snow fell. The northern portions of the Texas Permian
Basin reported snowfall amounts generally in the 1-3 inch range
overnight and this morning.

Even with the majority of the snow moving east of the area, the
forecast this evening into the tomorrow morning remains quite
difficult.  Both the Canadian and NAM models show very light
precipitation across a large portions of the CWA, generally along
and east of the mountains, this evening and then continuing into
Saturday morning.  The GFS also indicates overnight precipitation,
primarily over the northern portions of the CWA.  However, the GFS
is having some real struggles handling this winter weather event.
Thus, have trended our forecast towards the NAM and Canadian models.

A warm later around 750 mb is expected to develop later this evening
and overnight.  As this occurs, we will see a transition from light
snow to light freezing drizzle.  In addition, areas of freezing fog
are expected to develop along and east of the mountains as well.

This sets up for an interesting situation.  While we are not
anticipating significant accumulations of ice, there is certainly
potential for minor ice accumulations that will affect bridges and
overpasses.  In addition, the loss of sun angle will refreeze some
wet roadways across the area.  Thus, while not meeting formal
thresholds for a winter weather advisory, we believe the impact
warrants issuance of a winter weather advisory beginning later this
evening and continuing until noon CST tomorrow.

We should finally see a warmup beginning late tomorrow afternoon as
we finally warm above freezing into the 40s.  Sunday temperatures
should be much more in line with climatological normals with highs
in the 60s.

A weak cold front will push into the area on Monday with another
reinforcement of colder air on Wednesday.  Even with cooler air
moving into the area, it will not be near as cold as what we are
experiencing now.  For now, will maintain slight to chance POPs
across the central and eastern portions of the CWA through
mid-week.

.PREV DISCUSSION... /ISSUED 1057 AM CST Fri Feb 27 2015/

DISCUSSION...
See aviation discussion below.

AVIATION...
MVFR to IFR conditions will continue at the west Texas and southeast
New Mexico terminals the next 24 hours. Fog and occasional very
light snow pellets and very light freezing drizzle will continue.

PREV DISCUSSION... /ISSUED 616 AM CST Fri Feb 27 2015/

DISCUSSION...
See aviation discussion below.

AVIATION...
Winter wx in form of SN/FZDZ are the main aviation concerns with mostly
MVFR CIGS. Winter wx mainly impacting HOB/MAF with SN/FZDZ there,
respectively. Improvement is expected by around 15-16Z with light
precip possible into the overnight. Low PoPs preclude mention in
TAFs however. Will continue MVFR CIGS through the TAF period.

PREV DISCUSSION... /ISSUED 544 AM CST Fri Feb 27 2015/

UPDATE...

Issued update to expand the Winter Weather Advisory to include
central and southern portions of the Permian Basin.

DISCUSSION...

Freezing drizzle is occurring in Midland, so the Winter Weather
Advisory has been expanded to include central and southern portions
of the Permian Basin.  Freezing fog is also possible across this
area due to the low dew point depressions.  Freezing drizzle and
freezing fog have been added to the forecast grids for this morning
to reflect these changes.

PREV DISCUSSION... /ISSUED 520 AM CST Fri Feb 27 2015/

DISCUSSION...

Light to moderate snow is currently falling across southeast New
Mexico, northern and central portions of the Permian Basin, and the
Western Low Rolling Plains.  The snow is expected to shift eastward
today and will primarily affect the northeastern Permian Basin and
Western Low Rolling Plains by this afternoon.  Along and south of
the Pecos River, any precipitation that falls may be a mixture of
snow, sleet, and rain.  Temperatures are well below freezing and
will not get above freezing across most of the Permian Basin and
southeast New Mexico this afternoon.  A High Wind Warning is in
effect for high winds through Guadalupe Pass and will expire at 8 am
MST today.  A Winter Weather Advisory is in effect through this
morning for the Guadalupe Mountains, southeast New Mexico, and the
northern Permian Basin.  Total snowfall amounts in this area can be
expected to be around 1 to 4 inches.  Patchy fog is also possible
this morning mainly in the Guadalupe Mountains.

The wintry precipitation is expected to continue through Saturday
with the best chances being across the Western Low Rolling Plains
and the eastern Permian Basin.  High temperatures on Saturday will
warm up into the 40s and 50s across much of the area so
precipitation will transition over to rain as afternoon approaches.
Do not expect much in the way of snow accumulations on Saturday.

An upper trough will begin developing just off the coast of
California over the weekend with the upper flow becoming westerly to
southwesterly.  Temperatures on Sunday are expected to warm up to
near normal values as surface winds become southerly and the clouds
decrease in coverage.  There is a slight chance of rain across the
very far eastern CWA.  On Monday, the upper trough will move closer
to the region increasing upper lift over the area.  Showers with an
isolated thunderstorm may develop Monday afternoon as a result of
the increase in lift.  High temperatures on Monday are not expected
to be quite as warm due to an increase in cloud cover.  Temperatures
will warm slightly on Tuesday with a slight chance of rain across
the Guadalupe Mountains and portions of Eddy and Lea Counties as the
upper trough gets closer to the region.  The upper trough will begin
passing over the area on Wednesday with the models keeping most of
the precipitation north of the CWA.  The models are showing a cold
front associated with the upper trough moving into the area either
on Wednesday or Thursday.  Temperatures are expected to cool to
below normal by Thursday behind the front.

.AVIATION...
The main aviation concern for this TAF cycle will be low cigs likely
affecting all terminals for the next 24 hours. Currently have MVFR
ceilings across the board with elevated E/NE winds in place. Some
light radar returns now showing up over SE NM and western Permian
Basin. Expect to see light snow at CNM then spread east and south
through at least Friday morning. Visibility restrictions will be
possible at times with periods of heavier snow. MVFR cigs look to
affect all terminals through much of the day Friday. The NAM MOS
continues to show ceilings drop to IFR Friday evening but confidence
is too low to include mention attm. For now, will continue MVFR
through the TAF period and make adjustments if needed.

.AVIATION...
00Z TAF issuance...
The main aviation concern for the next 24 hours is low cigs/vis
affecting terminals, potentially through the end of this TAF cycle.
Currently have MVFR ceilings reported at all but INK, although the
cloud deck should drop back down at INK shortly. MVFR cigs look to
affect all sites through at least mid-day Friday, if not longer.
Will keep MVFR going through the 24 hour TAF period and make
adjustments if conditions look to improve, however there is a
chance conditions could deteriorate late afternoon Friday. Light
snow is expected to develop just after midnight at NM terminals
and quickly spread east and south. Visibility restrictions will be
possible at times with periods of heavier snowfall. Otherwise,
gusty NE winds may diminish slightly late tonight as winds slowly
veer to the east.

.PREV DISCUSSION... /ISSUED 340 PM CST Thu Feb 26 2015/

DISCUSSION...

Temperatures will continue to fall across the area tonight as
cold air advection continues in the wake of a cold front that
moved through the region early in the day. A few light snow/sleet
showers have moved across southeastern New Mexico and the Permian
Basin through this afternoon, though little to no accumulation has
resulted. This will change tonight, however, as low and midlevel
moisture will increase ahead of a disturbance that will move
through the region over the next 24 hours. This increased moisture
will result in the development of snow, first across southeastern
New Mexico this evening, gradually spreading southeast across the
Trans Pecos and Permian Basin overnight. The greatest
accumulations are expected to be over Lea county New Mexico as
well as the northern Permian Basin, where 2 to 4 inches of snow
are possible through late Friday morning. Accumulations may also
be enhanced on the lee side of higher terrain across Eddy county
New Mexico as well as the Guadalupe Mountains of southwest Texas
in Culberson county due to upslope flow generated by a brisk
easterly to northeasterly wind. Thus, a Winter Weather Advisory
has been issued through late Friday morning for the aforementioned
areas, so please see the appropriate product for details. South of
the advisory area, mainly across the southern Permian Basin and
Trans Pecos, 1 to 2 inches of snow accumulation are possible
before the disturbance shifts to the east of the area on Friday
afternoon. Have also gone ahead and upgraded the High Wind Watch
for the Guadalupe Mountains to a High Wind Warning tonight through
Friday morning, with brisk northeast winds expected to gust up to
65mph in the Warning area. Please see that appropriate product for
further details.

Friday looks to be the coldest day of the next week, with highs
ranging from the low to middle 20s across far southeastern New
Mexico and northern Permian Basin, to upper 40s and low 50s near the
Rio Grande. Breezy east to northeast winds will also result in
widespread wind chill values in the single digits and teens
through midday Friday. Have also trended a bit cooler over areas
expected to see the most snowfall both on Friday and Friday night.
The threat of a wintry mix of precipitation will continue through
Saturday, mainly across the far eastern Permian Basin and Western
Low Rolling Plains, before a return to southerly surface winds
late Saturday mark the beginning of a warming trend that will
continue through the middle of next week. The warming trend will
be further supported by yet another shortwave rounding the back of
the longwave CONUS trough, which will begin to dig south across
the west coast, resulting in southwesterly flow at 850mb by
Sunday. Near to even slightly above normal temperatures in the low
to mid 60s to low 70s are expected from Sunday through Wednesday,
and there`s another chance for rain across portions of the area
Sunday night through Monday night. As the aforementioned trough
over the western US begins to move east on Tuesday, the focus for
precipitation will shift north, yielding a dry forecast for late
in the extended. By next Wednesday night/Thursday, another cold
front associated with the upper trough looks to impact the area,
though the GFS is roughly 12 hours faster with this feature than
the ECMWF, so will maintain near normal temperatures on Wednesday,
and then slightly cooler for Thursday, with highs once again
dropping below normal into the 50s.

DISCUSSION...
Radar and observations show light snow falling from near Gail, to
Snyder, to Colorado City this morning. There may be some light
accumulations of up to around 1/2", which should limit impacts
across this area though temperatures are below freezing so caution
should be exercised especially along I-20 near Colorado City. Snow
will diminish this afternoon but more is possible later tonight.

MVFR CIGS have made it to HOB, nearing CNM and an hr or so out

be the trend at other sites thru the mid morning. MVFR CIGS are
generally expected to hold thru the day, possibly lifting some late
before lowering again overnight. There will be an increased chance
of snow tonight especially at HOB and have included prevailing
-SHSN toward end of the forecast there.

PREV DISCUSSION... /ISSUED 514 AM CST Thu Feb 26 2015/

DISCUSSION...

North to northeast winds are across the area with light snow showers
across northern portions of the Permian Basin and southeast New
Mexico.  Colder temperatures are moving into the region behind the
cold front with highs expected to be in the 40s and 50s across most
of the area.  There is a slight chance of a snow/sleet/light rain mix
across the northern Permian Basin, southeast New Mexico, the
Guadalupe Mountains, and the Upper Trans Pecos today with a broad
upper trough in place across most of the conus.  High winds are
possible through Guadalupe Pass this evening through early tomorrow
morning as the pressure gradient increases across this area.  MOSS
guidance is indicating high winds for this time period so a High
Wind Watch is being issued.  Precipitation chances will increase
across the area tonight with the best chances being across northern
Lea County and the northern Permian Basin.  Expect precipitation
across this area to be in the form of snow with a mixture of sleet
and snow possible further south to the mountains of West Texas.  A
rain/snow mix will be possible across the Big Bend and southern
Terrell County.

The precipitation will gradually shift to the east on Friday
afternoon with highs in the 20s across most of the Permian Basin.
The wintry precipitation is expected to continue through Saturday
with the best chances being across the Western Low Rolling Plains,
eastern Permian Basin, and Lower Trans Pecos.  High temperatures on
Saturday will warm up into the 40s and 50s across much of the area
so precipitation will transition over to rain as afternoon
approaches.  Up to 2 inches of snow is possible across northern Lea
County with an inch or more possible across the northern Permian
Basin.  Did not issue a Winter Weather Advisory at this time
although one may need to be issued later today depending on
forecasted QPF/snow amounts.  Will go ahead and issue an SPS to
cover the hazards.

An upper trough will begin developing just off the coast of
California over the weekend with the upper flow becoming westerly to
southwesterly.  Temperatures on Sunday are expected to warm up to
near normal values as surface winds become southerly and the clouds
decrease in coverage.  On Monday, the upper trough will move closer
to the region increasing upper lift over the area.  Showers with an
isolated thunderstorm may develop Monday afternoon as a result of
the increase in lift.  High temperatures on Monday are not expected
to be quite as warm due to an increase in cloud cover.  Temperatures
will warm slightly on Tuesday with a slight chance of rain across
the Guadalupe Mountains as the upper trough gets closer to the
region.  The upper trough will begin passing over the area on
Wednesday with the models keeping most of the precipitation north of
the CWA.  Strong west winds are expected on Wednesday as the base of
the upper trough moves over the area.  A cold front associated with
the upper trough will move into the area Wednesday evening allowing
for colder temperatures on Thursday.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
514 AM CST Thu Feb 26 2015

.DISCUSSION...

North to northeast winds are across the area with light snow showers
across northern portions of the Permian Basin and southeast New
Mexico.  Colder temperatures are moving into the region behind the
cold front with highs expected to be in the 40s and 50s across most
of the area.  There is a slight chance of a snow/sleet/light rain mix
across the northern Permian Basin, southeast New Mexico, the
Guadalupe Mountains, and the Upper Trans Pecos today with a broad
upper trough in place across most of the conus.  High winds are
possible through Guadalupe Pass this evening through early tomorrow
morning as the pressure gradient increases across this area.  MOSS
guidance is indicating high winds for this time period so a High
Wind Watch is being issued.  Precipitation chances will increase
across the area tonight with the best chances being across northern
Lea County and the northern Permian Basin.  Expect precipitation
across this area to be in the form of snow with a mixture of sleet
and snow possible further south to the mountains of West Texas.  A
rain/snow mix will be possible across the Big Bend and southern
Terrell County.

The precipitation will gradually shift to the east on Friday
afternoon with highs in the 20s across most of the Permian Basin.
The wintry precipitation is expected to continue through Saturday
with the best chances being across the Western Low Rolling Plains,
eastern Permian Basin, and Lower Trans Pecos.  High temperatures on
Saturday will warm up into the 40s and 50s across much of the area
so precipitation will transition over to rain as afternoon
approaches.  Up to 2 inches of snow is possible across northern Lea
County with an inch or more possible across the northern Permian
Basin.  Did not issue a Winter Weather Advisory at this time
although one may need to be issued later today depending on
forecasted QPF/snow amounts.  Will go ahead and issue an SPS to
cover the hazards.

An upper trough will begin developing just off the coast of
California over the weekend with the upper flow becoming westerly to
southwesterly.  Temperatures on Sunday are expected to warm up to
near normal values as surface winds become southerly and the clouds
decrease in coverage.  On Monday, the upper trough will move closer
to the region increasing upper lift over the area.  Showers with an
isolated thunderstorm may develop Monday afternoon as a result of
the increase in lift.  High temperatures on Monday are not expected
to be quite as warm due to an increase in cloud cover.  Temperatures
will warm slightly on Tuesday with a slight chance of rain across
the Guadalupe Mountains as the upper trough gets closer to the
region.  The upper trough will begin passing over the area on
Wednesday with the models keeping most of the precipitation north of
the CWA.  Strong west winds are expected on Wednesday as the base of
the upper trough moves over the area.  A cold front associated with
the upper trough will move into the area Wednesday evening allowing
for colder temperatures on Thursday.
