AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1139 AM CST Thu Jan 29 2015

.DISCUSSION...
We have opted to go ahead and start the NPW for GDP Pass earlier
with winds increasing there in the last hr. Products will be
updated shortly for that.

&&

.AVIATION...
Gusty post-frontal NE winds will prevail today with G25-30kts most
sites, a little less farther s. Meanwhile clouds will increase thru
the day and into the night, but are not expected to fall below MVFR
before 12Z/Fri.


&&

.PREV DISCUSSION... /ISSUED 521 AM CST Thu Jan 29 2015/

DISCUSSION...

The latest Aviation Discussion is included below.

AVIATION...

A cold front will push south through all area terminals through
29/18Z with gusty north to northeast winds in it`s wake.  Ceilings
and visibilities will stay VFR through the day, and even overnight
as surface winds gradually decrease.

PREV DISCUSSION... /ISSUED 452 AM CST Thu Jan 29 2015/

The stage is set for another round of unsettled weather beginning
tonight and continuing through at least Saturday night. A cold
front is currently sagging south through southeast New Mexico and
the Permian Basin. This front will continue to push south as an
upper level trough moves across the Ohio Valley and east coast
today. Behind this front temperatures will get knocked back to
near normal values this afternoon. In addition, strong northeast
winds will channel through Guadalupe Pass behind this front
tonight and Friday morning and a High Wind Warning has been issued
for that area.

In the upper levels a potent southern stream system currently
along the west coast will close off and intensify and move slowly
southeast across the desert southwest and then east across Mexico
the next several days. Ahead of this low, strong large scale
forcing is expected to produce a high probability of widespread
precipitation beginning tonight through Saturday night. Also, as
this upper low moves toward the region the northern stream will
continue to supply colder low level air. Forecast soundings
indicate the potential for a mixed bag of rain, snow, sleet tonight
through Friday and or Saturday night across the Guadalupe
Mountains and portions of the southeast New Mexico Plains. Still
not sure how much snow accumulation will occur in the Guadalupe
Mountains because the NAM model is showing a pronounced and
persistent mid level warm layer while the GFS model is not. If it
turns out that the warm layer is minimal, than a few inches of
snow and sleet could accumulate in the higher elevations of the
Guadalupes. Outside of that region, the best chance of any
accumulating snow will be across the northern third of Lea County
New Mexico tonight through Friday night, but less than 1 inch is
expected in a best case scenario at this time per a blend of
model soundings.

By Sunday the upper level trough axis is expected to approach the
area with the upper low sinking south and weakening through
Mexico. The better forcing will diminish and shift away from the
area as the upper low sinks south, so precipitation chances will
be on the decrease. In addition by this time period the lower
levels of the atmosphere are progged to warm up enough for the
precipitation to fall as rain.

By Sunday night through next Wednesday the upper level low
pressure system is forecast to continue to weaken and move
across Mexico with precipitation expected to remain south
of the forecast area. Temperatures will moderate to normal by
next Tuesday and Wednesday as a surface lee trough/low forms.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
953 PM CST Wed Jan 28 2015

DISCUSSION...

See 06Z Aviation Discussion below.

AVIATION...

VFR conditions will prevail next 24 hours. Latest NAM buffer soundings
put fropa at KHOB at around 12Z...and KCNM/KFST at 19Z, w/gusty
post-frontal conditions into the evening. Cigs behind the front
should have bases 5 kft agl or higher.

PREV DISCUSSION... /ISSUED 231 PM CST Wed Jan 28 2015/

DISCUSSION...

Models continue to show the next upper level low moving into
northwestern Mexico by the weekend bringing widespread
precipitation to our area. Rainfall will develop around the Van
Horn area late Thursday and spread east Friday into Saturday.
Vertical sounding profiles still show temperatures too warm for
snow for most areas, with the best chances for snow being in the
Guadalupe Mountains, southeast New Mexico, and the northwestern
Permian Basin. There is some disagreement between guidance and raw
model data forecast dewpoints and temperatures which could affect
the precipitation type. Guidance suggests temperatures will be cold
enough to support snow for roughly all areas north of I-20 while
the raw data is too warm for snow. Given the large amount of
precipitation it may be difficult for dewpoints to drop low enough
for evaporative cooling to lower the temperatures so this forecast
continues with mostly rain. Models have backed off slightly on QPF
amounts, but PWATs double the norm for this time of year mean some
locations could receive in excess of an inch of rain. An upper low
in January 2013 brought over an inch of rain and some flooding to
Midland so it is definitely possible. The warm temperatures and
wet ground will make it difficult for any snow that falls to
accumulate, but one to two inches would not be out of the
question, especially in the higher elevations of the Guadalupe
Mountains.

The moisture will push off to the east on Sunday bringing an end
to the rain while the upper low slowly meanders into central
Mexico. A modest ridge will develop over the western U.S. keeping
us in northwesterly flow and allowing for only a slow warm up
early next week with highs reaching near normal by Tuesday.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1138 AM CST Wed Jan 28 2015

.DISCUSSION...
Please see the 18Z aviation discussion below.

&&

.AVIATION...
A cold front will move into Southeast New Mexico and West Texas
after 09z. This will result in a surface wind shift to the
north. Surface winds behind the front will be breezy. Increasing
high level cloudiness is expected. However, VFR conditions are
expected area wide through the forecast period.

&&

.PREV DISCUSSION... /ISSUED 511 AM CST Wed Jan 28 2015/

DISCUSSION...

Another mild day is in store for southeast New Mexico and west Texas
today.  As a matter of fact, it`ll be pretty warm with temperatures
rising nearly 20 degrees above normal and challenging record highs.
This will occur as a surface trough strengthens over the southern
U.S. Plains and into the region ahead of a cold front.  Enjoy today
since temperatures will drop back to around normal levels Thursday,
especially north of Interstate 10.  Behind the front Thursday night,
gap winds in the Guadalupes may rise to at least 35 to 45 mph, so
will make a mention in the Hazardous Weather Outlook for now.  The
forecast will turn wet thereafter as a highly amplified upper trough
currently off the California coast heads east.

Temperatures will be cooler Thursday, and as the associated surface
ridge settles south into the area Thursday night, we should see rain
begin to break out over the western half of the forecast area.  This
will occur as low level easterly upslope flow combines with deep
layer lift ahead of a mid level shortwave trough and the approach of
the RRQ of a 90kt h25 jet.  Eastward progress of the rain may be a
little slow through the day Friday, but should become widespread
over the entire area Friday night as the above features move
overhead.  Therefore, have tempered rain chances a little over the
eastern CWA Friday, but increased PoPs areawide Friday night.  Some
wintry precipitation could mix in late Thursday night, Friday and
Friday night.  Forecast soundings indicate precipitation could
change to sleet or snow around 6kft in the Guadalupes, if not
northern Lea County.  Did not go with much accumulation since
temperatures through the atmospheric column are only marginally
conducive for some bursts of sleet and/or snow, heights/thicknesses
ahead of the upper trough are not very low and lastly surface
temperatures are just not very cold.  Later shifts will have to
monitor for any changes in any, or all, of the above.  For now, will
make a mention of a mix possible in these areas.  There could be
some localized, but minor flooding problems Friday and Friday night
as pwats rise to around 1 inch, or 2 s.d. above normal.  The best
moisture will head east on Saturday, and take the better rain
chances with it.

An elongated, positively tilted ua trough will extend over the
region by Saturday night.  An upper low will calve from this ua
trough and sink well south over Mexico.  There may be some light
precipitation over the area on Saturday night and Sunday as another
cold front moves south into the area.  The only shot at wintry
precipitation appears to be the Guadalupe Mountains and portions of
southeast New Mexico again.  Since moisture will be a little more
scarce, do not think there will be any appreciable accumulations.
Cooler than normal temperatures will prevail through early next
week, but it appears near to above normal readings will be possible
Tuesday and beyond.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
335 AM CST Wed Jan 28 2015

.DISCUSSION...

Another mild day is in store for southeast New Mexico and west Texas
today.  As a matter of fact, it`ll be pretty warm with temperatures
rising nearly 20 degrees above normal and challenging record highs.
This will occur as a surface trough strengthens over the southern
U.S. Plains and into the region ahead of a cold front.  Enjoy today
since temperatures will drop back to around normal levels Thursday,
especially north of Interstate 10.  Behind the front Thursday night,
gap winds in the Guadalupes may rise to at least 35 to 45 mph, so
will make a mention in the Hazardous Weather Outlook for now.  The
forecast will turn wet thereafter as a highly amplified upper trough
currently off the California coast heads east.

Temperatures will be cooler Thursday, and as the associated surface
ridge settles south into the area Thursday night, we should see rain
begin to break out over the western half of the forecast area.  This
will occur as low level easterly upslope flow combines with deep
layer lift ahead of a mid level shortwave trough and the approach of
the RRQ of a 90kt h25 jet.  Eastward progress of the rain may be a
little slow through the day Friday, but should become widespread
over the entire area Friday night as the above features move
overhead.  Therefore, have tempered rain chances a little over the
eastern CWA Friday, but increased PoPs areawide Friday night.  Some
wintry precipitation could mix in late Thursday night, Friday and
Friday night.  Forecast soundings indicate precipitation could
change to sleet or snow around 6kft in the Guadalupes, if not
northern Lea County.  Did not go with much accumulation since
temperatures through the atmospheric column are only marginally
conducive for some bursts of sleet and/or snow, heights/thicknesses
ahead of the upper trough are not very low and lastly surface
temperatures are just not very cold.  Later shifts will have to
monitor for any changes in any, or all, of the above.  For now, will
make a mention of a mix possible in these areas.  There could be
some localized, but minor flooding problems Friday and Friday night
as pwats rise to around 1 inch, or 2 s.d. above normal.  The best
moisture will head east on Saturday, and take the better rain
chances with it.

An elongated, positively tilted ua trough will extend over the
region by Saturday night.  An upper low will calve from this ua
trough and sink well south over Mexico.  There may be some light
precipitation over the area on Saturday night and Sunday as another
cold front moves south into the area.  The only shot at wintry
precipitation appears to be the Guadalupe Mountains and portions of
southeast New Mexico again.  Since moisture will be a little more
scarce, do not think there will be any appreciable accumulations.
Cooler than normal temperatures will prevail through early next
week, but it appears near to above normal readings will be possible
Tuesday and beyond.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
947 PM CST Tue Jan 27 2015

DISCUSSION...

See 06z Aviation Discussion below.

AVIATION...

VFR conditions will prevail next 24 hours. Generally light
westerly sfc flow will continue, w/a few high clouds.

PREV DISCUSSION... /ISSUED 149 PM CST Tue Jan 27 2015/

DISCUSSION...
The main feature of interest is an upper low over the Western US.
The initial low looks to move off to the NE around the top of a
ridge over the center of the country... but a secondary low off the
coast develops into a deep trough by late Thursday as it moves
ashore and becoming cut off by Friday.  Still uncertainty in the
models as to if this low just spins across Mexico into next week or
kicks out.

Have cooled temps a few degrees tonight and warmed Wednesdays
readings.  An upper ridge over the area will result in another warm
day on Wednesday with a west wind at the surface.  A cold front
looks to blow through early Thursday with a fairly brisk fropa.  NE
wind will be chilly and veer around to the E by evening.  Should
have increasing mid and high clouds ahead of the low as Pacific
moisture flows into the region.

Precip chances start Thursday night out west and spread east across
the area Friday through Sunday.  Shortwaves ejecting out ahead of
the low will provide plenty of lift.  Most of the precip should be
as rain as temps look too warm.  Snow mainly confined to the
Guadalupes.  Late Friday into Saturday looks to be the best chance
of precip.  Model soundings show PW in the Permian Basin pushing up
to close to an inch... could end up with good rainfall.  Actually
have had well above normal precipitation year to date and have
potential to get a good amount more.  Briefly discussed possibility
of a Flash Flood Watch but will hold off for now... will emphasis in
the HWO.

.AVIATION...

VFR conditions and light westerly winds this TAF period.

&&

.PREV DISCUSSION... /ISSUED 342 AM CST Tue Jan 27 2015/

DISCUSSION...

Mid and high cloud will decrease today as moisture at these levels
heads into an upper ridge axis over the region.  Pretty good heating
will occur across the forecast area with temperatures rising a good
10 to 15 degrees above normal.  The same appears to be on tap
Wednesday as the upper ridge remains over the region, except highs
could be closer to 15 to 20 degrees above normal.  A shortwave
trough will translate southeastward through the northern/central
U.S. Plains Wednesday, and send a cold front south into the area
Thursday.  We should see temperatures closer to seasonal norms,
especially as mid and high cloud begin to increase ahead of a sharp
upper trough off the California coast/Baja Peninsula.

A cool surface high will become entrenched over the forecast area
Thursday night while copious amounts of mid and upper level moisture
stream northeastward over the region ahead of the mentioned ua
trough.  A series of mid level shortwave troughs will move over the
region ahead of the ua trough, and along with the RRQ of a 90kt h25
jet, promote large scale ascent above the cool surface airmass.  No
instability is indicated above the boundary layer, and mid level
lapse rates are paltry, so do not think we will see any convection.
However, rain will become widespread over the area, then last
through the day Friday before tapering off somewhat Friday night/
Saturday morning as the best moisture shifts east of the area.
Models bring precipitable water values to near 1 inch across the
forecast area, which is 2 standard deviations above normal!
Moderate to heavy rainfall could result in 1 to 2 inches amounts in
a few locations, and could lead to minor flooding problems.
Although the air through the atmospheric column may be cold enough
to support some snowfall in the Guadalupe Mountains and southeast
New Mexico Plains Friday and Friday night, think the rainfall rates
will be great enough to overwhelm cooler surface temperatures and
keep readings above freezing.  Therefore, will carry only negligible
snowfall amounts in those areas.

The upper trough could linger over Mexico into early next week.
Models diverge on it`s movement so have cloven a path down the
middle.  This entails another cold front moving into the area
Sunday, along with a slight chance of mainly rain.  Will keep
temperatures near normal through the rest of the forecast period
and have little to no chance of precipitation after Sunday.

PREV DISCUSSION... /ISSUED 249 PM CST Mon Jan 26 2015/

DISCUSSION...

Above normal temperatures are being seen this afternoon and
westerly upper level flow will continue this trend through
Wednesday. Attention remains focused on an upper level low moving
into northwestern Mexico bringing precipitation to the area
beginning late Thursday. Initially an upper trough moving into the
Central Plains will push a weak cold front south early Thursday,
but it is the upper level low farther west that will provide the
precipitation. Models continue to show a very good chance for rain
starting out west on Friday, centered around Midland Friday night,
with highest rain chances shifting east on Saturday.

The precipitation type remains the biggest uncertainty in this
forecast. The upper low becomes disconnected from the northern
stream westerlies thus is not able to tap into colder air from
Canada. Evaporational cooling will chill the air some but forecast
soundings show it will be a borderline rain/snow/sleet event. The
best chance for wintry precipitation will be in the Guadalupe and
Davis Mountains as well as southeast New Mexico and the
northwestern Permian Basin. Still not expecting much accumulations
due to the marginal temperatures and this system may be much like
our most recent one where most melted upon hitting the ground. The
biggest concern may actually be rainfall amounts as most models
are showing one to two inches of rainfall is possible perhaps
creating minor flooding issues. Rainfall amounts will largely
depend on the progression of the upper low and models are
notoriously bad at progging the movement of cutoff lows along the
U.S./Mexico border. Fortunately there are still several days
before this system impacts our area.

.AVIATION...
VFR with copious amounts of high clouds expected. Wind will be
light and generally out of the west.

&&

PREV DISCUSSION... /ISSUED 400 AM CST Mon Jan 26 2015/

DISCUSSION...

Sfc obs show another relatively warm night shaping up across West
Texas and Southeast New Mexico, in generally northwest flow, aided
by a fetch of subtropical moisture streaming a veil of high clouds
across the region in zonal flow aloft.  WV imagery shows the upper
cut-off low west of Baja, while to the east, an upper trough is
exiting the MS Valley.  These two features have sandwiched a
highly-amped ridge over the area.  Baja ridge is still forecast to
shear out and rejoin the flow over the next few days, flattening the
ridge and sending it east.  As the trough moves north, isolated
-SHRA can`t be ruled out this evening over the Presidio Valley.
Otherwise, the ridge, combined w/a light westerly downslope flow
component, will result in continued unseasonably warm temperatures
over the next few days.  By Wednesday afternoon, it`ll feel more
light mid May around here than late January, as afternoon highs top
out in the 70s.

Unfortunately, the shearing Baja trough is forecast to top the
ridge, and join forces w/a shortwave diving out of Canada, dropping
a cold front into the FA late Wednesday night.  This will knock
temps back down Thursday afternoon, although still abv normal.  As
this is taking place, another upper trough will reach the west
coast, and is forecast to close off over SoCal/SW AZ sometime
Friday.  This will set up West Texas/SE NM for a wet weekend, w/a
chance of -SHRA beginning as soon as Thursday night, exacerbated by
isentropic upglide beginning Friday, as the trough begins sending
shortwaves into the area in SW flow aloft.  A secondary cold front
is due in Friday night/Saturday to help things along, although the
GFS is a little faster w/fropa than the ECMWF.  Mid/hi-lvl moisture
from the west and easterly low-lvl moisture will saturate the column
by 00Z Saturday, w/the GFS developing PWATs over 1" by then...over 3
std devs abv normal and abv the 99th percentile for January.  Thus,
the potential for abundant rainfall persists.  Precip should remain
liquid Thu night/Fri, as the secondary front arrives Friday night at
the earliest.  Attm, forecast soundings for Fri night/Sat suggest a
mix will be possible only in the N and NW fringes of the FA.
Saturday night could see a changeover to -SN most areas, but
soundings dry out considerably from 00Z-12Z Sun, so accumulations
should be minimal.  Precip continues tapering off Sunday.

No aviation concerns for the next 24 hours, VFR conditions will

PREV DISCUSSION... /ISSUED 234 PM CST Sun Jan 25 2015/

DISCUSSION...
A cold front moved through the area this morning but you wouldn`t
know it looking at the temperatures. Highs today will actually be
warmer than they were yesterday with a northerly wind shift the
only evidence of the frontal passage. The upper pattern early this
week will feature weak ridging/westerly flow which will continue
above normal highs into Wednesday.

Thursday is when we will see a major shift in the weather pattern
as an upper low digs into southern California creating a split jet
over the western CONUS. The northern stream will edge up into
western Canada and drop into the Central Plains pushing a cold
front into Texas on Thursday. This will provide some cooling, but
the southern stream will be the one to watch as it advects
moisture off the Pacific and brings a return of precipitation. The
GFS continues to be the most aggressive in not only the areal
extent of the rainfall, but also in duration and QPF though the
other models are definitely trending towards the wetter solution.
Have upped PoPs to "likely" for much of the area Friday night into
Saturday which is certainly a rarity for so far out in the
forecast but model consensus provides more confidence than usual
in this wet forecast. Precipitation is expected to start Thursday
night and continue all the way into Sunday thanks to a very slow
moving or perhaps even stationary upper low to our west.

The biggest uncertainty in this forecast is temperatures, as they
will be very close to the rain/sleet/snow cutoff. The split nature
of the upper pattern will prevent very cold air from filtering
south with 850-700mb temperatures anywhere from +2C to -3C. Much
of the cooling may come from evaporational processes which are
difficult to forecast a week out. Therefore will start the
p-type as rain into Friday mixing some snow in by Saturday and
Sunday. Since temperatures are so marginal for wintry precip, it
does not appear at this time there will be much opportunity for
significant accumulations but this will have to be closely
monitored over the next several days.

.AVIATION...

VFR conditions are expected for the next 24 hours.  Winds will
continue shifting to the north this morning then to the northeast
this afternoon as a cold front comes through the area. Winds will
become light and variable this evening.

&&

.PREV DISCUSSION... /ISSUED 400 AM CST Sun Jan 25 2015/

DISCUSSION...

Sfc obs show a weak cold front to the north of the region, w/buffer
soundings bringing fropa to KMAF at around 10Z.  Otherwise, a
relatively warm night is on tap in modest westerly flow under a
fetch of high clouds streaming in from the west.  Further west, WV
imagery shows a massive cut-off low separated from upper-lvl flow
and parked off the coast of Baja.  In between this trough and NW
flow to the east, models develop a highly-amped ridge over West
Texas/Southeast New Mexico over the next few days.  This feature is
forecast to build east and flatten into midweek as the upper trough
shears out as it moves NE back into the jetstream.  As the trough
shears, it is forecast to send a shortwave thru the western zones
Monday night, for a slight chance of showers there.  Upper ridging
will allow for a brief respite from the cold temps of late.  By
Tuesday, temps will top out in the low 70s for much of the region,
making it feel more like early May than late January.

Unfortunately, this warmer wx comes to an end late Wednesday night
as the aforementioned upper trough dives into the MS Valley, and
drops a cold front into the region Thursday.  Temps should still
stay abv-normal Thursday afternoon, but drop blo normal Friday and
Saturday.  During this time, another trough will separate from the
flow off the west coast near Baja.  This feature is a little further
NE than the current one, and likely to result in increased chances
of precip for the FA as it sends shortwaves thru SW flow aloft
beginning late Thursday.  Both the GFS and ECMWF are similar
w/placement of the trough off the coast of Baja, while the DGEX
wants to take it to srn CA/AZ.  Models bring in considerable
mid/hi-lvl moisture from the SW, while return flow pumps sfc
dewpoints to near 40F by Friday night.  PWATs at KMAF increase to
over 1" by 00Z Saturday...over 3 std devs abv normal and abv the
99th percentile, so the potential to score some decent rainfall
will be there.  Attm, forecast soundings suggest precip will fall as
rain, as lower lvls stay abv freezing deep enough to melt any ice in
the column.  The only exception might be the extreme N/NW, which may
see a mix Friday night.  Chances for frozen precip look better
Saturday night, but that is beyond this forecast.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1113 PM CST Sat Jan 24 2015

.DISCUSSION...

See 06z aviation discussion below.

&&

.AVIATION...

No major aviation concerns for the next 24 hours, VFR conditions
will prevail at all terminals. Light westerly winds will begin to
veer to the north through the morning as a cold front moves through
the region.  Significant wind speeds are not expected behind the
front.

&&

PREV DISCUSSION... /ISSUED 251 PM CST Sat Jan 24 2015/

DISCUSSION...
It has turned out to be a beautiful day with mostly clear skies
and temperatures around normal. Northwesterly upper flow will
bring a cold front into the area tomorrow, but there will be
little if any cold air behind it so expect temperatures to be much
like today. An upper ridge will move across west Texas Monday and
break down leaving westerly upper flow Tuesday and Wednesday
sending temperatures above normal. A weak trough Monday night will
only bring a slight chance for rain showers for areas west of the
Pecos River.

The GFS has been very consistent and continues to show a good
chance for precipitation late next week. The ECMWF is trending
towards the GFS and now all models are developing an upper level
low near the Baja of Mexico with a highly amplified ridge laying
over the Pacific Northwest. This splits the jet into two streams
but a particularly strong southern stream will advect moisture out
of the Pacific and into New Mexico and Texas. Precipitation would
develop Thursday night and continue through the weekend. The GFS
remains most aggressive with QPF amounts though all models are
showing the areal coverage to be extensive. It should be noted
that PoPs are quite high for Day 6/7 in the forecast with 40-50
percent across most of the region.

The northern stream jet will bring a cold front on Thursday and
modestly cooler temperatures. Most of the cooling may actually
come from cloud cover and precipitation thus the precipitation
type will be rain. The upper low only slowly moves east across
northern Mexico so southwest flow ahead of the low will provide
warm air advection and keep the p-type rain through Saturday and
the end of the forecast period. Sunday (just outside of this
forecast), another front may arrive with colder air and the chance
for the rain to change to a wintry precip type so this system will
need to be closely monitored.

PREV DISCUSSION... /ISSUED 417 AM CST Sat Jan 24 2015/

DISCUSSION...

A broad upper trough is over the eastern conus and Upper Midwest
with a closed low strengthening off the coast of Mexico south of
California this morning.  Temperatures will warm up into the 50s
across most of the area this afternoon with light westerly winds.
An even greater warm up is expected on Sunday with temperatures in
the 60s for most of the area and remaining warm through Thursday.
Some locations across the Western Low Rolling Plains, eastern
Permian Basin, and Lower Trans Pecos may see high temperatures in
the 70s beginning on Monday. The upper pattern is expected to not
change much with an upper trough remaining over the eastern conus
and upper ridging over the western half of the conus.  The
previously mentioned closed low will allow for a slight chance of
rain Monday afternoon through Monday night for mainly locations
along and west of the Upper Trans Pecos as mid-level moisture from
this low gets pulled over the region. Models show this closed low
becoming embedded within the upper ridge and moving northward and
weakening by Tuesday afternoon.  An upper trough moving over the
Upper Midwest will send a cold front through the area on Thursday
cooling temperatures into the lower 60s depending on the timing of
the front.

Beginning next Thursday/Friday, the models show another closed low
developing just off the coast of California and moving eastward
heading into next weekend.  Both the GFS and ECMWF are showing
precipitation beginning on Thursday and lasting through next weekend
over the CWA associated with this low.  The precipitation appears to
be scattered across the area on Friday resulting in even cooler
temperatures than those on Thursday. An upper trough moving over the
Northern Plains will send a strong cold front southward into the
area next Saturday.  The precipitation across the area looks to be
mostly in the form of rain until this cold front passes through the
region.  After the frontal passage, wintry precipitation is possible
beginning Saturday night.  Since this is still a week away, will
continue to monitor this system as it develops and moves closer.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
417 AM CST Sat Jan 24 2015

.DISCUSSION...

A broad upper trough is over the eastern conus and Upper Midwest
with a closed low strengthening off the coast of Mexico south of
California this morning.  Temperatures will warm up into the 50s
across most of the area this afternoon with light westerly winds.
An even greater warm up is expected on Sunday with temperatures in
the 60s for most of the area and remaining warm through Thursday.
Some locations across the Western Low Rolling Plains, eastern
Permian Basin, and Lower Trans Pecos may see high temperatures in
the 70s beginning on Monday. The upper pattern is expected to not
change much with an upper trough remaining over the eastern conus
and upper ridging over the western half of the conus.  The
previously mentioned closed low will allow for a slight chance of
rain Monday afternoon through Monday night for mainly locations
along and west of the Upper Trans Pecos as mid-level moisture from
this low gets pulled over the region. Models show this closed low
becoming embedded within the upper ridge and moving northward and
weakening by Tuesday afternoon.  An upper trough moving over the
Upper Midwest will send a cold front through the area on Thursday
cooling temperatures into the lower 60s depending on the timing of
the front.

Beginning next Thursday/Friday, the models show another closed low
developing just off the coast of California and moving eastward
heading into next weekend.  Both the GFS and ECMWF are showing
precipitation beginning on Thursday and lasting through next weekend
over the CWA associated with this low.  The precipitation appears to
be scattered across the area on Friday resulting in even cooler
temperatures than those on Thursday. An upper trough moving over the
Northern Plains will send a strong cold front southward into the
area next Saturday.  The precipitation across the area looks to be
mostly in the form of rain until this cold front passes through the
region.  After the frontal passage, wintry precipitation is possible
beginning Saturday night.  Since this is still a week away, will
continue to monitor this system as it develops and moves closer.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
1123 PM CST Fri Jan 23 2015

.DISCUSSION...

See 06Z Aviation Discussion below.

&&

.AVIATION...

No aviation concerns for the next 24 hours, VFR conditions will
persist at all terminals with light NW winds and mostly clear skies
in place.

&&

PREV DISCUSSION... /ISSUED 248 PM CST Fri Jan 23 2015/

DISCUSSION...

Visible satellite images from this morning showed nicely where
snow fell yesterday and overnight, which was much of west Texas
and southeast New Mexico. However the latest images show most snow
is melted and the heaviest snow fell in the higher elevations west
of the Pecos River and northern Lea County. We were fortunate
road conditions overall were not too bad though a sudden drop into
the mid 20s in the Midland/Odessa area around sunrise caused roads
to briefly become very slick.

The upper trough that caused the snow is moving off to the east
with the upper pattern developing into a Rex block (upper high
situated north of an upper low) by the weekend. This will split
the westerlies into a southern and northern stream with the south
plains being the convergence point of these two jets. We will
initially be under the influence of the northern stream which will
bring clear skies and above normal temperatures through the middle
of next week. A disturbance in the southern stream will approach the
area early next week but will weaken as it moves into a ridge and
only bring a slight chance of showers west of the Pecos.

The block briefly breaks down mid week but becomes reestablished
by next weekend. The difference with this second blocking pattern
is that current models are indicating the southern stream will be
stronger and exert more influence over our weather. This would
advect moisture and instability across northern Mexico and into
Texas and New Mexico by the end of next week. The GFS is the
wettest model by far and may be too wet given a weak upper ridge
centered right over our CWA so have only introduced a slight
chance for showers at the very end of the forecast. The GFS is not
only wettest, but it is the coldest model showing the northern
stream bringing cold air down south interacting with the southern
stream for another possibility of wintry precip next weekend. This
however is after the valid period of this forecast so there is
plenty of time to monitor this next potential system.

UPDATE...

Issued update to extend the Winter Storm Warning and Winter
Weather Advisory across eastern and central portions of the Permian
Basin, the Western Low Rolling Plains, and the Lower Trans Pecos
through 9 am CST.

DISCUSSION...

Snow is continuing across eastern and central portions of the
Permian Basin, the Western Low Rolling Plains, and the Trans Pecos
and is slower in moving out of the area than previously
anticipated.  Due to this reason, have decided to extend the
previously mentioned portions of the Winter Storm Warning and Winter
Weather Advisory until 9 am CST.

PREV DISCUSSION... /ISSUED 415 AM CST Fri Jan 23 2015/

DISCUSSION...

Snow continues to move across the Permian Basin and the Trans Pecos
this morning with temperatures near or below freezing.  Models might
be too quick with moving the precipitation out of the CWA so might
need to extend the eastern part of the Winter Storm Warning and
Winter Weather Advisory for a couple more hours.  The upper trough
that is over the region and contributing to the snow is expected to
move over eastern TX this afternoon.  This will cause the
precipitation to move out of the area today, and surface winds will
become westerly by this afternoon.  The surface high moving to the
east today will allow for temperatures this afternoon to warm up
into the 40s across most of the area.

A broad upper trough will be over the eastern conus and Upper
Midwest with a closed low taking shape off the coast of Mexico south
of California beginning on Saturday.  Temperatures will warm up into
the 50s across most of the area on Saturday.  An even greater warm
up is expected on Sunday with temperatures in the 60s and remaining
this warm through Thursday.  The upper pattern is expected to not
change much with an upper trough remaining over the eastern conus
and upper ridging over the western half of the conus.  Models show
the previously mentioned closed low becoming embedded within the
upper ridge and moving northward and weakening.  This upper pattern
will allow for fairly dry conditions for the area through
Wednesday.  Beginning next Thursday/Friday, the models show another
closed low developing south of California and moving eastward
heading into next weekend.  Depending on the timing of this upper
low, it could be wet across the area next Friday so have increased
pops as a result.  A cold front is also expected to move into the
area next Thursday/Friday.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MIDLAND/ODESSA TX
415 AM CST Fri Jan 23 2015

.DISCUSSION...

Snow continues to move across the Permian Basin and the Trans Pecos
this morning with temperatures near or below freezing.  Models might
be too quick with moving the precipitation out of the CWA so might
need to extend the eastern part of the Winter Storm Warning and
Winter Weather Advisory for a couple more hours.  The upper trough
that is over the region and contributing to the snow is expected to
move over eastern TX this afternoon.  This will cause the
precipitation to move out of the area today, and surface winds will
become westerly by this afternoon.  The surface high moving to the
east today will allow for temperatures this afternoon to warm up
into the 40s across most of the area.

A broad upper trough will be over the eastern conus and Upper
Midwest with a closed low taking shape off the coast of Mexico south
of California beginning on Saturday.  Temperatures will warm up into
the 50s across most of the area on Saturday.  An even greater warm
up is expected on Sunday with temperatures in the 60s and remaining
this warm through Thursday.  The upper pattern is expected to not
change much with an upper trough remaining over the eastern conus
and upper ridging over the western half of the conus.  Models show
the previously mentioned closed low becoming embedded within the
upper ridge and moving northward and weakening.  This upper pattern
will allow for fairly dry conditions for the area through
Wednesday.  Beginning next Thursday/Friday, the models show another
closed low developing south of California and moving eastward
heading into next weekend.  Depending on the timing of this upper
low, it could be wet across the area next Friday so have increased
pops as a result.  A cold front is also expected to move into the
area next Thursday/Friday.

.DISCUSSION...
See aviation discussion below.

.AVIATION...
Main aviation concern for the next 24 hours will be low cigs/vis
affecting terminals through Friday morning. Generally have IFR/LIFR
cigs and vis at most sites tonight however some locations are
showing a brief improvement to MVFR for the time being. This should
be short-lived as new model runs show conditions getting much worse
with fog/LIFR vis developing in the next few hours. Currently have
-SN reported at all terminals at 05Z but periods of moderate snow
may result in lower vis than what is forecasted. Conditions expected
to improve by mid morning Friday with precip ending from NW to SE.

AVIATION...
00Z TAF issuance...
Main aviation concern for the next 24 hours will be low cigs/vis
affecting terminals overnight. Currently have IFR/LIFR cigs and vis
across the board this evening with mainly -SN reported at all
but PEQ, where -RA will likely change to -SN tonight. Expect this to
continue overnight into the early morning hours Friday. Snow should
remain light most of the time however periods of moderate/heavy snow
may occur, lowering visibilities beyond what is forecasted.
Conditions expected to improve by mid morning Friday with precip
ending from NW to SE.

PREV DISCUSSION... /ISSUED 310 PM CST Thu Jan 22 2015/

DISCUSSION...

The upper level low serving as the driving force behind today`s
wintry weather continues to dig southward across southwestern New
Mexico toward far west Texas. Recent water vapor imagery shows a
plume of moisture continuing to stream over the area ahead of the
low. Infrared satellite also shows cooling cloud tops across
southeastern New Mexico and southwest Texas, evidence of the
increasing amount of lift overspreading the area ahead of the
approaching trough. Much of the area has seen a rain and snow mix
for most of the day today, though accumulations have generally
been under an inch as ground temperatures remain warm and snow is
melting as it falls. The exception to this is across southeastern
New Mexico and in the Guadalupe Mountains, where 4 to 6 inches of
accumulation have already been reported. As temperatures drop this
evening to near/below freezing, expect all snow to prevail, and
accumulations to increase across the area. Overnight, the axis of
heaviest snow will gradually shift south over the Lower Trans
Pecos and Davis Mountains. Still think the going storm total snow
accumulations look to be on track, with roughly a widespread 2-4
inches of accumulation, and upwards of 6 to 7 inches across the
higher terrain of the Guadalupe, Davis, and Apache Mountains. A
Winter Storm Warning remains in effect until Friday morning for
southeast New Mexico, the western and central Permian Basin, Upper
Trans Pecos, and locations south and west of the Pecos River
excluding the Presidio Valley and Terrell County. A Winter Weather
Advisory also remains in effect through Friday morning for the
eastern and southern Permian Basin. Please refer to the
Warning/Advisory products for details.

Temperatures will begin to rebound on Friday as the trough axis
finally swings through the area, ushering precipitation to the east,
with dry conditions expected by Friday afternoon. The warming trend
will continue into next week as a 500mb ridge develops, extending
from south Texas northwestward toward the Pacific Northwest.
Temperatures will rise well into the 60s by Wednesday, though the
ridge will begin to flatten out by Wednesday afternoon as upper
level flow splits and yet another southern stream trough begins
to dig south over the west coast. Currently, the GFS and ECMWF
solutions diverge in their handling of the aforementioned trough for
the end of next week, with the ECMWF developing a cutoff low off
of the Baja Peninsula by late week, versus the GFS which maintains
an open wave, but quite a bit more moisture. Given the
uncertainties that far out, have elected to maintain only sub-
mentionable PoPs in the extended at this time.
