1133 AM CST SUN FEB 1 2015

.AVIATION...
LOW STRATUS WILL CONTINUE TO BREAK UP BY EARLY AFTERNOON AS DRIER
LOW LEVEL AIR FILTERS INTO THE REGION BEHIND A COLD FRONT.
AFTERWARDS...VFR WILL PREVAIL. WINDS WILL INCREASE OUT OF THE
SOUTHWEST LATE MONDAY MORNING IN RESPONSE TO A DEEPENING LOW
PRESSURE SYSTEM IN EASTERN COLORADO.

SHORT TERM...
THE UA LOW THAT PROVIDED THE REGION WITH BENEFICIAL RAINFALL FOR THE
SOUTH PLAINS AND ROLLING PLAINS YESTERDAY...AND RESULTED IN A RECORD
BREAKING RAINFALL FOR KLBB...WAS GRADUALLY TRANSLATING SSE ACROSS
WRN OLD MEXICO EARLY THIS MORNING. ADDITIONAL SHOWERS ARE NOT
EXPECTED THIS MORNING GIVEN ITS SRN LATITUDE...HOWEVER MOIST GROUNDS
AND LIGHT S-SW SFC WINDS HAVE RESULTED IN THE DEVELOPMENT OF LOW
CLOUDS /WITH INTERMITTENT DRIZZLE/ AND FOGGY CONDITIONS ACROSS
PORTIONS OF THE CWA. VIS HAVE RANGED FROM 7 MILES AT KPVW...4 MILES
AT KLBB AND 3 MILES AT KCDS PER 08Z METARS. VIS CONDITIONS ARE
BETTER AT KLBB AND KPVW LIKELY GIVEN THE W-SW WIND...WHICH IS A
DOWNSLOPE COMPONENT THAT AIDS IN DRIER CONDITIONS /VERSUS LIGHT
AND VARIABLE FLOW AT KCDS/. VIS CONDITIONS COULD BRIEFLY
DETERIORATE LATER THIS MORNING...THAT IS UNTIL AN UA SHORTWAVE
PROGRESSING EAST ACROSS THE CENTRAL/NORTHERN PLAINS SENDS DOWN A
COLD FRONT TO IMPINGE ON THE REGION AOA 12Z AND CLEARING THE SRN
ZONES BETWEEN 15Z- 18Z. THIS FRONT WILL CAUSE SFC WINDS TO VEER TO
THE W-NW AND FINALLY TO THE NORTH WHICH WILL RESULT IN PWATS
DROPPING FROM 0.60-0.75 INCHES DOWN TO BELOW 0.50 INCHES AFTER THE
FROPA...THUS DRYING OUT LOW LEVELS AND SCOURING OUT ANY LINGERING
FOG...LOW CLOUDS AND HENCE DRIZZLE. A TIGHTENED PRESSURE GRADIENT
AND PRESSURE RISES ON THE ORDER OF 4-6 MB PER 3 HOURS SUGGEST NRLY
WIND SPEEDS WILL INCREASE INTO THE 15-20 MPH EARLY THIS AFTN. THE
GRADIENT WILL RELAX BY LATE AFTN/EARLY EVENING LEADING TO
DECLINING WIND SPEEDS WHILST WINDS VEER TO THE E-NE.

CLEARING SKIES THROUGHOUT THE DAY WILL ALLOW TEMPS TO WARM INTO THE
40S ON THE CAPROCK TO THE UPPER 40S TO LOWER 50S OFF THE
CAPROCK...WHICH IS A FEW DEGREES WARMER THAN YESTERDAY.
HOWEVER...CLEAR SKIES AND LIGHT S-SE SFC WINDS WILL CAUSE OVERNIGHT
TEMPS TO FALL INTO THE 20S.

LONG TERM...
NO SIG CHANGES TO THE FCST THIS MORNING. MODELS REMAIN CONSISTENT
WITH A NWLY FLOW ALOFT ACROSS THE SRN HIGH PLAINS IN A FAIRLY
STAGNANT WRN CONUS UPPER RIDGE AND ERN CONUS UPPER TROUGH PATTERN.
FAIRLY MINOR CHANGES TO THE AMPLITUDE OF THE UPPER PATTERN AND
TIMING OF SHORT WAVE TROUGHS MOVING THROUGH THE FLOW WILL BRING
CHANGES TO SENSIBLE WX ACROSS THE FCST AREA THIS WEEK.

FAIRLY BREEZY CONDITIONS MONDAY AND POSSIBLY AGAIN TUESDAY AS LEE

.AVIATION...
CONDITIONS HAVE AT LEAST TEMPORARILY IMPROVED AT KLBB AND KCDS
THROUGH IT IS EXPECTED THAT VARYING FLIGHT RULES WILL OCCUR OVER
THE NEXT 6 HOURS. HOWEVER...CONFIDENCE IN SPECIFYING JUST HOW LOW
THINGS WILL GO AND WHEN IS LOW. FOR NOW HAVE ELECTED TO GO
CONSERVATIVE WITH THE FCST. HOWEVER...CONDITIONS BELOW LOCAL
MINIMA IS POSSIBLE AS PLENTIFUL MOIST ADVECTION WILL CONTINUE
INTO THE REGION. A COLD FRONT WILL PUSH INTO THE AREA JUST BEFORE
DAYBREAK SUNDAY MORNING. THEREAFTER VFR.

&&

.PREV DISCUSSION... /ISSUED 745 PM CST SAT JAN 31 2015/

UPDATE...
GIVEN RADAR TRENDS...HAVE PULLED MENTION OF PRECIPITATION THIS
EVENING INTO TOMORROW MORNING. A FEW SCATTERED SHOWERS MAY OCCUR
IN THE VERY MOIST AIRMASS BEFORE THE COLD FRONT ARRIVES AROUND
SUNRISE BUT LIKELIHOOD IS EXPECTED TO BE LESS THAN 10 PCT.


PREV DISCUSSION... /ISSUED 257 PM CST SAT JAN 31 2015/

SHORT TERM...
PRECIPITATION IS ENDING THIS AFTERNOON AS THE LARGE SCALE LIFT WANES
WITH LITTLE REDEVELOPMENT EXPECTED THIS EVENING. THE UPPER LOW OVER
SOUTHERN CALIFORNIA WAS DROPPING SOUTH INTO MEXICO CONTRIBUTING TO
DRYING OUT AT MID LEVELS. AT THE SAME TIME...A NORTHERN STREAM
TROUGH AXIS WAS RACING THROUGH THE ROCKIES WHICH WILL FURTHER DRY
OUT THE MID AND UPPER LEVELS OF THE ATMOSPHERE. THIS NORTHERN STREAM
TROUGH WILL BRING IN STRONGER SUBSIDENCE AS WELL. ALTHOUGH THE LIFT
IS DEPARTING...LOW LEVEL MOISTURE WILL HANG AROUND THROUGH TOMORROW
MORNING. WITH MOIST GROUNDS FROM RAINFALL...FOG WILL BE A POSSIBILITY
FOR SUNDAY MORNING. THE AFOREMENTIONED NORTHERN STREAM TROUGH WILL
DRAG A COLD FRONT THROUGH AFTER DAYBREAK ON SUNDAY WHICH WILL RID US
OF THE LOW LEVEL MOISTURE AND STRONG NORTHERLY WINDS IN ITS WAKE.

LONG TERM...
BREEZY CONDITIONS WILL ALSO BE OF CONCERN GOING INTO THE LONG
RANGE AS A SURFACE TROUGH DEEPENS ALONG THE LEE OF THE ROCKIES ON
MON. THIS IN RESPONSE TO ENERGY DIVING INTO THE SOUTHERN ROCKIES
IN NORTHWEST FLOW ALOFT. MODELS HINTING AT AN INCREASE IN LOW AND
MID LEVEL MOISTURE AHEAD OF THE WAVE EARLY IN THE DAY. SOUTHERLY
WINDS WILL ALSO HELP ADVECT HIGHER DEWPOINT AIR ACROSS SOUTHEAST
AND EASTERN NM. WHILE TIMING OF THIS ISN`T FAVORABLE FOR DENSE
FOG SOME LOW STRATUS WILL BE POSSIBLE ACROSS WESTERN ZNS EARLY IN
THE DAY. TEMPERATURES WILL CONTINUE TO MODERATE MON INTO MID WEEK AHEAD
OF THE NEXT COLD FRONT FORECAST TO BACKDOOR THROUGH THE PNHDL
DURING THE DAY WED. OPTED TO BRING COOLER HIGHS INTO THE NORTHEAST
AND NORTHERN SECTIONS WITH THE FRONT WHILE ALLOWING FOR GOOD
COMPRESSIONAL HEATING AND TEMPS EDGING INTO THE 60S FURTHER SOUTH.
BREEZY CONDITIONS ARE EXPECTED BEHIND THE FRONT WED EVENING INTO
VERY EARLY THU WITH ANOTHER DECENT SHOT OF MID LEVEL ENERGY IN NW
FLOW ALOFT DIRECTED ACROSS THE PNHDL AND OKLAHOMA. THU STANDS TO
BE THE COOLEST DAY OF THE WEEK WITH A QUICK WARMUP INTO THE 60S
AND POSSIBLY BEYOND TO END THE WEEK. POPS REMAIN BELOW CLIMATOLOGY
THROUGH THE PERIOD AS DRY NW FLOW ALOFT IS NOT CONDUCIVE TO
PRECIP ALONG OR AHEAD OF THE FRONTAL BOUNDARY WED.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
257 PM CST SAT JAN 31 2015

.SHORT TERM...
PRECIPITATION IS ENDING THIS AFTERNOON AS THE LARGE SCALE LIFT WANES
WITH LITTLE REDEVELOPMENT EXPECTED THIS EVENING. THE UPPER LOW OVER
SOUTHERN CALIFORNIA WAS DROPPING SOUTH INTO MEXICO CONTRIBUTING TO
DRYING OUT AT MID LEVELS. AT THE SAME TIME...A NORTHERN STREAM
TROUGH AXIS WAS RACING THROUGH THE ROCKIES WHICH WILL FURTHER DRY
OUT THE MID AND UPPER LEVELS OF THE ATMOSPHERE. THIS NORTHERN STREAM
TROUGH WILL BRING IN STRONGER SUBSIDENCE AS WELL. ALTHOUGH THE LIFT
IS DEPARTING...LOW LEVEL MOISTURE WILL HANG AROUND THROUGH TOMORROW
MORNING. WITH MOIST GROUNDS FROM RAINFALL...FOG WILL BE A POSSIBILITY
FOR SUNDAY MORNING. THE AFOREMENTIONED NORTHERN STREAM TROUGH WILL
DRAG A COLD FRONT THROUGH AFTER DAYBREAK ON SUNDAY WHICH WILL RID US
OF THE LOW LEVEL MOISTURE AND STRONG NORTHERLY WINDS IN ITS WAKE.

.LONG TERM...
BREEZY CONDITIONS WILL ALSO BE OF CONCERN GOING INTO THE LONG
RANGE AS A SURFACE TROUGH DEEPENS ALONG THE LEE OF THE ROCKIES ON
MON. THIS IN RESPONSE TO ENERGY DIVING INTO THE SOUTHERN ROCKIES
IN NORTHWEST FLOW ALOFT. MODELS HINTING AT AN INCREASE IN LOW AND
MID LEVEL MOISTURE AHEAD OF THE WAVE EARLY IN THE DAY. SOUTHERLY
WINDS WILL ALSO HELP ADVECT HIGHER DEWPOINT AIR ACROSS SOUTHEAST
AND EASTERN NM. WHILE TIMING OF THIS ISN`T FAVORABLE FOR DENSE
FOG SOME LOW STRATUS WILL BE POSSIBLE ACROSS WESTERN ZNS EARLY IN
THE DAY. TEMPERATURES WILL CONTINUE TO MODERATE MON INTO MID WEEK AHEAD
OF THE NEXT COLD FRONT FORECAST TO BACKDOOR THROUGH THE PNHDL
DURING THE DAY WED. OPTED TO BRING COOLER HIGHS INTO THE NORTHEAST
AND NORTHERN SECTIONS WITH THE FRONT WHILE ALLOWING FOR GOOD
COMPRESSIONAL HEATING AND TEMPS EDGING INTO THE 60S FURTHER SOUTH.
BREEZY CONDITIONS ARE EXPECTED BEHIND THE FRONT WED EVENING INTO
VERY EARLY THU WITH ANOTHER DECENT SHOT OF MID LEVEL ENERGY IN NW
FLOW ALOFT DIRECTED ACROSS THE PNHDL AND OKLAHOMA. THU STANDS TO
BE THE COOLEST DAY OF THE WEEK WITH A QUICK WARMUP INTO THE 60S
AND POSSIBLY BEYOND TO END THE WEEK. POPS REMAIN BELOW CLIMATOLOGY
THROUGH THE PERIOD AS DRY NW FLOW ALOFT IS NOT CONDUCIVE TO
PRECIP ALONG OR AHEAD OF THE FRONTAL BOUNDARY WED.

SUB-VFR CONDITIONS ARE EXPECTED TO PERSIST THROUGH MID MORNING ON
SUNDAY. ALTHOUGH LIGHT PRECIPITATION WILL END THIS AFTERNOON TO
LATE EVENING CIGS WILL REMAIN IN IFR TO LIFR WITH LOW LEVEL
MOISTURE REMAINING IN PLACE ACROSS THE REGION. MOIST LOW LEVELS
WILL ALSO KEEP A CHANCE AT LOWERED VISBYS AS WELL THROUGH THE
OVERNIGHT HOURS. A STRONG COLD FRONT WILL SWEEP THROUGH THE AREA
AROUND DAYBREAK ON SUNDAY SCOURING OUT LOW CIGS AND VISBYS.
HOWEVER...WINDS WILL BECOME STRONG OUT OF THE NORTH BEHIND THIS
FRONT.

HINTS OF THAT ALSO BEING A POSSIBLITY AT KPVW AND KLBB AS METARS
REPORTED SCT IFR DECKS. SOUTHEAST SURFACE WINDS WILL VEER TO THE
WEST NORTHEAST BY TONIGHT. BKN VFR TO MVFR DECKS WILL BE COMMON
TONIGHT. THERE ARE HINTS OF MVFR FOG DEVELOPING OVERNIGHT AT ALL

SHORT TERM...
THE UA LOW ACROSS SERN NV/NWRN AZ CONTINUED TO PROVIDE NW FLOW ALOFT
ACROSS THE REGION AND THUS CONTINUED TO PUMP MID-UPPER LEVEL PACIFIC
MOISTURE ACROSS THE FA. LOOKING AT THE SFC...AN UPSLOPE SFC REGIME
HAS ALLOWED FOR THE TRANSPORT OF LOW LEVEL GULF MOISTURE TO ENVELOPE
THE AREA...LEADING TO PWATS IN THE 0.80-1.00 INCH RANGE EARLY THIS
MORNING /HIGHEST PWATS NOTED ACROSS THE ROLLING PLAINS/. ALL OF
THESE FACTORS INCLUDING MORE THAN ADEQUATE LARGE SCALE ASCENT
PROVIDED BY THE AFOREMENTIONED UA LOW HAS RESULTED IN THE WIDESPREAD
LIGHT TO MODERATE RAIN SHOWERS MOVING NE ACROSS THE SOUTH PLAINS AND
NORTHERN ROLLING PLAINS PER 08Z RADAR ANALYSIS. TEXAS TECH MESONET
SITES HAVE REPORTED RAINFALL AMOUNTS OF A FEW HUNDREDTHS OF AN
INCH UP TO A TENTH OF AN INCH OR SO PER HOUR THUS FAR. TEMPS HAVE
FALLEN TO NEAR THE FREEZING MARK ACROSS THE NWRN SOUTH PLAINS
WHICH COULD POSE A RISK OF LIGHT SNOWFALL MIXING IN WITH SNOW.
HOWEVER...SNOWFALL ACCUMULATIONS LOOK RATHER LACKLUSTER GIVEN
VEERING WIND PROFILES SUGGESTING APPRECIABLE WARM ADVECTION AS
WELL AS A PREVALENT WARM NOSE AOA 800 MB. THOUGH...PROGGED MODEL
SOUNDINGS AT FRIONA SHOW A BRIEF PERIOD OF THE WARM NOSE
DETERIORATING IN THE NEXT FEW HOURS AND WITH A TEMP OF 33 F...IT
WILL BE A CLOSE CALL. A PHONE CALL TO EMERGENCY PERSONNEL RESULTED
IN ONLY RAIN FALLING AND NOT SNOW ATTM. IF IT DOES MANAGE TO
SNOW...THE /WET/ SNOWFALL THAT WILL MORE SO ACCUMULATE ON GRASSES
WILL LIKELY BE LESS THAN 1.00 INCH AS HINTED AT BY THE NAM...GFS
AND NATIONAL SNOWFALL MODELS THANKS TO A LACK OF A SIGNIFICANT
COLD AIRMASS. IN REGARD TO RAINFALL TOTALS...1/2 INCH TO 1.00 INCH
WILL FALL THROUGH TONIGHT MAKING FOR A BENEFICIAL SOAKING.

THE WIDESPREAD PRECIP WILL BE SHIFTING FROM WEST TO EAST BY THIS
AFTN AS DRYER AIR FILTERS IN FROM THE TOP DOWN HENCE EVIDENT OF
DECREASING LARGE SCALE ASCENT. THIS PROBABLY DUE TO THE THE UA LOW
BEING A BIT TO FAR SOUTH AS IT IS ANTICIPATED TO SHIFT SE TO ACROSS
THE BAJA OF CALI/WRN OLD MEXICO...RESULTING IN UNSHARPENED SWRLY
FLOW ALOFT. COULD SEE LINGERING RAINFALL /AND PERHAPS VERY LIGHT
SNOW MIXED IN ACROSS THE NWRN ZONES/ TONIGHT BEFORE THE ACTIVITY
FINALLY EXITS THE REGION JUST BEYOND THE SHORT TERM PERIOD. BKN
CLOUD COVER VERSUS OVC SKIES MAY BE ENOUGH TO ALLOW TEMPS TO WARM
INTO THE 40S. TONIGHT...OVERNIGHT LOWS WILL RANGE FROM THE LOWER 30S
ACROSS THE SW TX PANHANDLE/NW SOUTH PLAINS TO THE MIDDLE TO UPPER
30S ACROSS MOST OF THE REMAINING AREAS.

LONG TERM...
A COLD FRONT WILL MOVE THRU THE FCST AREA EARLY SUNDAY IN THE WAKE
OF THE DEPARTING UPPER TROUGH. HOWEVER...WITH DECREASING CLOUD
COVER LEADING TO INCREASED INSOLATION WILL SEE TEMPS WARM SOME
OVER TODAYS HIGHS.

BEYOND SUNDAY...QUIET WEATHER THROUGH THE WEEK WITH AN UPPER RIDGE
TO BUILD OVER THE WRN CONUS RESULTING IN GENERALLY DRY NWLY UPPER
LEVEL FLOW OVER THE SRN HIGH PLAINS. A SHORT WAVE TROUGH WILL MOVE
QUICKLY SEWD FROM THE CENTRAL ROCKIES WEDNESDAY NIGHT PUSHING OUR

.SHORT TERM...
THE UA LOW ACROSS SERN NV/NWRN AZ CONTINUED TO PROVIDE NW FLOW ALOFT
ACROSS THE REGION AND THUS CONTINUED TO PUMP MID-UPPER LEVEL PACIFIC
MOISTURE ACROSS THE FA. LOOKING AT THE SFC...AN UPSLOPE SFC REGIME
HAS ALLOWED FOR THE TRANSPORT OF LOW LEVEL GULF MOISTURE TO ENVELOPE
THE AREA...LEADING TO PWATS IN THE 0.80-1.00 INCH RANGE EARLY THIS
MORNING /HIGHEST PWATS NOTED ACROSS THE ROLLING PLAINS/. ALL OF
THESE FACTORS INCLUDING MORE THAN ADEQUATE LARGE SCALE ASCENT
PROVIDED BY THE AFOREMENTIONED UA LOW HAS RESULTED IN THE WIDESPREAD
LIGHT TO MODERATE RAIN SHOWERS MOVING NE ACROSS THE SOUTH PLAINS AND
NORTHERN ROLLING PLAINS PER 08Z RADAR ANALYSIS. TEXAS TECH MESONET
SITES HAVE REPORTED RAINFALL AMOUNTS OF A FEW HUNDREDTHS OF AN
INCH UP TO A TENTH OF AN INCH OR SO PER HOUR THUS FAR. TEMPS HAVE
FALLEN TO NEAR THE FREEZING MARK ACROSS THE NWRN SOUTH PLAINS
WHICH COULD POSE A RISK OF LIGHT SNOWFALL MIXING IN WITH SNOW.
HOWEVER...SNOWFALL ACCUMULATIONS LOOK RATHER LACKLUSTER GIVEN
VEERING WIND PROFILES SUGGESTING APPRECIABLE WARM ADVECTION AS
WELL AS A PREVALENT WARM NOSE AOA 800 MB. THOUGH...PROGGED MODEL
SOUNDINGS AT FRIONA SHOW A BRIEF PERIOD OF THE WARM NOSE
DETERIORATING IN THE NEXT FEW HOURS AND WITH A TEMP OF 33 F...IT
WILL BE A CLOSE CALL. A PHONE CALL TO EMERGENCY PERSONNEL RESULTED
IN ONLY RAIN FALLING AND NOT SNOW ATTM. IF IT DOES MANAGE TO
SNOW...THE /WET/ SNOWFALL THAT WILL MORE SO ACCUMULATE ON GRASSES
WILL LIKELY BE LESS THAN 1.00 INCH AS HINTED AT BY THE NAM...GFS
AND NATIONAL SNOWFALL MODELS THANKS TO A LACK OF A SIGNIFICANT
COLD AIRMASS. IN REGARD TO RAINFALL TOTALS...1/2 INCH TO 1.00 INCH
WILL FALL THROUGH TONIGHT MAKING FOR A BENEFICIAL SOAKING.

THE WIDESPREAD PRECIP WILL BE SHIFTING FROM WEST TO EAST BY THIS
AFTN AS DRYER AIR FILTERS IN FROM THE TOP DOWN HENCE EVIDENT OF
DECREASING LARGE SCALE ASCENT. THIS PROBABLY DUE TO THE THE UA LOW
BEING A BIT TO FAR SOUTH AS IT IS ANTICIPATED TO SHIFT SE TO ACROSS
THE BAJA OF CALI/WRN OLD MEXICO...RESULTING IN UNSHARPENED SWRLY
FLOW ALOFT. COULD SEE LINGERING RAINFALL /AND PERHAPS VERY LIGHT
SNOW MIXED IN ACROSS THE NWRN ZONES/ TONIGHT BEFORE THE ACTIVITY
FINALLY EXITS THE REGION JUST BEYOND THE SHORT TERM PERIOD. BKN
CLOUD COVER VERSUS OVC SKIES MAY BE ENOUGH TO ALLOW TEMPS TO WARM
INTO THE 40S. TONIGHT...OVERNIGHT LOWS WILL RANGE FROM THE LOWER 30S
ACROSS THE SW TX PANHANDLE/NW SOUTH PLAINS TO THE MIDDLE TO UPPER
30S ACROSS MOST OF THE REMAINING AREAS.

.LONG TERM...
A COLD FRONT WILL MOVE THRU THE FCST AREA EARLY SUNDAY IN THE WAKE
OF THE DEPARTING UPPER TROUGH. HOWEVER...WITH DECREASING CLOUD
COVER LEADING TO INCREASED INSOLATION WILL SEE TEMPS WARM SOME
OVER TODAYS HIGHS.

BEYOND SUNDAY...QUIET WEATHER THROUGH THE WEEK WITH AN UPPER RIDGE
TO BUILD OVER THE WRN CONUS RESULTING IN GENERALLY DRY NWLY UPPER
LEVEL FLOW OVER THE SRN HIGH PLAINS. A SHORT WAVE TROUGH WILL MOVE
QUICKLY SEWD FROM THE CENTRAL ROCKIES WEDNESDAY NIGHT PUSHING OUR
NEXT COLD FRONT SWD AHEAD OF IT CAUSING A HALT TO WARMING CAUSED
BY INCREASING MID AND UPPER LEVEL HEIGHTS EARLY IN THE WEEK.

.UPDATE...
WIDESPREAD RAIN LOOKS TO CONTINUE OVERNIGHT AHEAD OF AN UPPER
LEVEL LOW PRESSURE SYSTEM MOVING INTO THE GREAT BASIN. TOTAL AMOUNTS
OF 1/2 TO 1 INCH SHOULD FALL THROUGH SATURDAY AS DEEP LAYER LIFT
AND MOISTURE REMAINS IN PLACE. ONLY CHANGE TO THE ONGOING FORECAST
WAS TO BACK OFF FURTHER ON SNOW TOTALS ACROSS THE FAR SOUTHWEST
PANHANDLE AND NORTHWEST SOUTH PLAINS AS VEERING WIND PROFILES
SUGGEST APPRECIABLE WARM AIR ADVECTION SET IN PLACE. LOCAL
AMDAR/ACARS DATA ALSO DEPICT A WARM NOSE WITHIN THE LOWEST SEVERAL
THOUSAND FEET. TEMPERATURES SHOULD FALL INTO THE LOW-MID 30S IN
THESE LOCATIONS...BUT OVERALL VERTICAL PROFILES DO NOT SUGGEST
LOW ENOUGH ICE CRYSTAL FORMATION FOR MUCH FROZEN PRECIPITATION AT
THE SURFACE. GIVEN THE LIKELY SCENARIO FOR MOSTLY RAIN...WILL LET
THE SPECIAL WEATHER STATEMENT EXPIRE AT MIDNIGHT FOR ALL AS
SNOWFALL ACCUMULATIONS SHOULD REMAIN BELOW 1 INCH INTO
NORTHWESTERN PARMER COUNTY.

&&

.AVIATION...
RAIN WILL CONTINUE TO OVERSPREAD ALL TAF SITES TONIGHT THROUGH
MUCH OF SATURDAY. MVFR CEILINGS WILL DETERIORATE TO IFR BY
DAYBREAK SATURDAY AS VISIBILITIES ALSO BECOME RESTRICTED WITH RAIN
INCREASING IN INTENSITY. MAY SEE LIFR OR EVEN PERIODS OF VLIFR
SATURDAY MORNING AND AFTERNOON AS RAIN CONTINUES. ANY THREAT OF
FROZEN PRECIPITATION SHOULD REMAIN WELL NORTH AND WEST OF ALL TAF
SITES...ALTHOUGH LOCAL PIREP REPORT DID RECORD LIGHT RIME ICING
AT FL110.

&&

PREV DISCUSSION... /ISSUED 244 PM CST FRI JAN 30 2015/

SHORT TERM...
PRECIPITATION CHANCES WILL RAMP UP THIS EVENING AS EXPECTED WITH
THE UPPER LOW TO THE WEST PUMPING UP THE MOISTURE INTO WEST TEXAS.
UPPER LEVEL DIVERGENCE WILL BEGIN TO SPREAD INTO THE AREA
OVERNIGHT. THIS WILL COUPLE WITH THE IMPRESSIVE DEEP LAYER
ISENTROPIC LIFT. THE MAXIMUM AMOUNT OF LIFT IS STILL LIKELY TO
OCCUR BETWEEN 00Z THIS EVENING THROUGH 18Z SATURDAY.
PRECIPITATION WILL BEGIN A WEST TO EAST TAPERING OFF ON SATURDAY
AFTERNOON AS DRIER AIR BEGINS TO PUNCH INTO THE AREA AS WELL AS AN
AREA OF DRYING/SUBSIDENCE MOVING IN FROM THE NORTH. CURRENT SHORT
WAVE RIDGING HAS MADE IT DIFFICULT FOR THE COLUMN TO COMPLETELY
SATURATE ESPECIALLY FOR AREAS OFF THE CAPROCK. DEW POINT
DEPRESSIONS ANYWHERE BETWEEN 10 AND 20 SPAN ACROSS THE FA FROM THE
SOUTHWESTERN PANHANDLE TO THE ROLLING PLAINS. MODELS GENERALLY
SHOW A VERY SLOW SATURATION OFF THE CAPROCK WITH LOW LEVELS NOT
BECOMING SATURATED UNTIL AFTER 06Z. BY THE TIME THE COLUMN DOES
SATURATE...PRECIPITABLE WATER VALUES WILL BE RESPECTABLE FOR
JANUARY WITH VALUES ON THE ORDER OF 0.8 INCHES ON THE CAPROCK AND
1 INCH OFF THE CAPROCK.

REGARDING PRECIPITATION TYPE...THE WARM AIR ADVECTION WILL OVERPOWER
ANYTHING ELSE LEADING TO MOSTLY RAIN EXCEPT FOR AREAS ACROSS THE
SOUTHWESTERN TEXAS PANHANDLE WHERE LESS WAA WILL BE SEEN. WITH A
LACK OF AN ARCTIC AIR INTRUSION...IT IS DIFFICULT TO SEE SIGNIFICANT
SNOWFALL OR FREEZING PRECIPITATION....ESPECIALLY UNDER STRONG WAA
REGIMES. TEMPERATURES WILL NOT FALL TOO MUCH OVERNIGHT AND THE
THREAT OF SIGNIFICANT ACCUMULATING SNOWFALL WILL BE SMALL. THE
SOUTHWESTERN TEXAS PANHANDLE MAY STILL SEE AN INCH OR TWO OF SNOW
BEFORE PRECIPITATION ENDS.

LONG TERM...
SUBSIDENCE AND DRYING SATURDAY NIGHT WILL GRADUALLY EDGE
DIMINISHING PRECIPITATION CHANCES FURTHER EAST. AN UPPER TROUGH
PASSING JUST NORTH EARLY SUNDAY ALONG WITH A COLD FRONTAL
SURGE...WILL ATTEMPT TO COUNTER THESE TRENDS AND LIKELY WILL BE
UNSUCCESSFUL. SO WE HAVE RETAINED DRY CONDITIONS FOR SUNDAY. BUT
ANOTHER COOL DAY SHOULD FOLLOW SUNDAY WITH CLOUDS THINNING AND
BREEZES TAPERING DURING THE AFTERNOON.

FROM THERE...DRY WEST TO NORTHWEST FLOW ALOFT WILL START THE WEEK
WITH A DECENT WARMING TO ABOVE NORMAL LEVELS BY TUESDAY AND
WEDNESDAY. THE ONLY FLY IN THE OINTMENT TO COME IS A MODERATE
STRENGTH THOUGH SHALLOW CANADIAN COLD FRONT DUE IN LATE WEDNESDAY.
SOLUTIONS HAVE TRENDED SLIGHTLY STRONGER WITH A SURFACE 1040-ISH
MILLIBAR SURFACE RIDGE DROPPING INTO THE NORTHERN PLAINS LATE IN
THE WEEK. AT THIS POINT WE SEE MAINLY THURSDAY AS A COOL DAY
FOLLOWED BY WARMING HEADING INTO THE WEEKEND. AND IT COULD BE A

NATIONAL WEATHER SERVICE LUBBOCK TX
1130 AM CST FRI JAN 30 2015

.AVIATION...
FLIGHT CONDITIONS ARE EXPECTED TO DETERIORATE THIS EVENING AS
WIDESPREAD RAINFALL MOVES INTO THE REGION. TEMPERATURES WILL
LIKELY BE WARM ENOUGH FOR ALL RAIN WITH LITTLE TO NO SNOW MIXING
IN. HOWEVER...AS LOW LEVEL MOISTURE CONTINUES TO INCREASE
TONIGHT...CONDITIONS WILL LIKELY FURTHER WORSEN TO IFR DURING THE
MID TO LATE MORNING HOURS ON SATURDAY.

&&

PREV DISCUSSION... /ISSUED 351 AM CST FRI JAN 30 2015/

SHORT TERM...
MAIN FOCUS IN THE SHORT TERM PERIOD CONTINUES TO BE INCREASING
CHANCES FOR PRECIP...AS AN UA LOW CONTINUES TO SLOWLY TRANSLATE EAST
JUST OFF THE COAST OF THE BAJA EARLY THIS MORNING. THIS SYSTEM HAS
PROMOTED SW FLOW ALOFT TO DOMINATE ACROSS THE REGION AND THUS STREAM
A PLUME OF PACIFIC MOISTURE ACROSS THE REGION. THE RESULT IS SCT-OVC
MID-UPPER LEVEL CLOUDINESS WHICH WILL PREVAIL THROUGH TOMORROW.
LOOKING AT THE SFC...A SFC RIDGE WAS NOTED NE OF THE CWA EARLY THIS
MORNING THEREBY AIDING SFC WINDS TO BE OF AN E-NE COMPONENT PER 08Z
METARS. THIS SLIGHT UPSLOPE WIND COMPONENT HAS GARNERED PWATS TO
INCREASE TO AOA 0.50 INCHES SO FAR. RADAR TRENDS DISPLAYED LIGHT
ECHOES ACROSS THE PERMIAN BASIN AND FAR SW SOUTH PLAINS...WHICH IS
INDICATIVE OF A BIT OF LARGE SCALE ASCENT THAT HAS COMMENCED TO
SHIFT DOWNSTREAM OF THE AFOREMENTIONED UA LOW. WITH SFC TEMPS IN THE
LOWER 40S ACROSS THE SW SOUTH PLAINS...THE PRECIP TYPE IS LIQUID. IN
FACT...THE SEMINOLE METAR HAS INTERMITTENTLY REPORTED DRIZZLE.
MOST MODEL SOLUTIONS DO NOT HAVE A GOOD HANDLE ON THE CURRENT
LIGHT PRECIP...WITH THE EXCEPTION OF THE TTU WRF WHICH SHOWS THIS
LIGHT PRECIP ACTIVITY TO PERSIST FOR THE NEXT SEVERAL HOURS AND
PERHAPS SHIFT A BIT TO THE NORTH AND EAST...THOUGH WANING WITH
TIME.

LATER THIS MORNING INTO THIS AFTN...SFC WINDS WILL VEER TO THE E-SE
AS THE SFC RIDGE SLIDES SE FARTHER AWAY FROM THE REGION. THIS
UPSLOPE SFC REGIME WILL ONLY ENCOURAGE PWATS TO INCREASE INTO THE
0.75-0.85 INCH RANGE...WITH HIGHEST PWATS NOTED ACROSS THE SRN AND
SWRN ONES.  MODEL SOLUTIONS DO AGREE THAT LARGE SCALE ASCENT WILL
ALSO INCREASE A BIT /PARTICULARLY ACROSS THE WRN ZONES/ WHILST
TOP- DOWN MOISTENING OCCURS. A WELL-DEFINED WARM NOSE BETWEEN 800
MB-750 MB AND SFC TEMPS WARMING INTO THE MIDDLE TO UPPER 30S WILL
PROMOTE MORE OF A WINTRY MIX /RAIN AND SNOW/ ACROSS THE WRN ZONES
VERSUS LIQUID RAINFALL ELSEWHERE. THIS EVENING INTO TONIGHT...BOTH
PWATS /0.75-1.00 INCH/ AND UL SUPPORT WILL BE MAXIMIZED DURING
THIS PERIOD AS THE UA LOW NEARS NWRN OLD MEXICO. TEMPS ALOFT WILL
COOL ESPECIALLY ACROSS THE FAR SW TX PANHANDLE AND NW SOUTH
PLAINS...HENCE RESULTING IN CHANCES OF SNOWFALL. MODEL SOUNDINGS
INDICATE MORE OF A RAIN AND SNOW MIX ACROSS MOST OF THE CAPROCK
AND RAINFALL OFF THE CAPROCK DURING THE SAID TIME-PERIOD. IT IS
INTERESTING TO NOTE THAT NATIONAL SNOWFALL MODELS AND EVEN THE
USUAL BULLISH GFS MODEL HAVE BACKED OFF ON THE /WET/ SNOWFALL
ACCUMULATION...BY SHOWING 1-2 INCH ACCUMULATIONS OCCURRING ACROSS
THE NW SOUTH PLAINS. THE NAM ON THE OTHER HAND IS A BIT MORE
AGGRESSIVE WITH 1-4 INCHES. HAVE GONE AHEAD AND TAPERED DOWN
SNOWFALL AMOUNTS A BIT...LEANING MORE SO TOWARDS 1-3 INCHES ACROSS
THE NW SOUTH PLAINS. AS SUCH...WINTER WEATHER HIGHLIGHTS BEYOND
THE SPECIAL WEATHER STATEMENT MAY BE WARRANTED...BUT WILL LET THE
NEXT FEW SHIFTS SEE IF RADAR TRENDS DO INDEED SHOW ACCUMULATING
SNOWFALL. TOMORROW...PRECIP WILL BE ONGOING BUT WILL BE SLOWLY
SHIFTING FROM WEST TO EAST. TEMPS WARMING ALOFT AND A SOME DRYING
OCCURRING IN THE MID-UPPER LEVELS WILL CAUSE THE PRECIP TYPE TO BE
ALL LIQUID BY LATE AFTN ACROSS MOST OF THE AREA /COULD STILL SEE A
RAIN AND SNOW MIX ACROSS THE NW ZONES/.

PER 08Z METARS...TEMPS ARE IN THE LOWER 30S ACROSS THE NW SOUTH
PLAINS TO THE LOWER 40S ELSEWHERE. WITH CONTINUED MID-UPPER LEVEL
CLOUD COVER /AND LOW CLOUDS DEVELOPING THIS EVENING/...TEMPS WILL
LIKELY NOT WARM MUCH THAN WHAT IT IS THIS MORNING. OVERNIGHT LOWS
WILL FALL TO THE UPPER 20S ACROSS THE NW TO THE UPPER 30S
SE...FOLLOWED BY HIGHS IN THE 40S TOMORROW.

LONG TERM...
PRECIP EVENT TO WIND DOWN SATURDAY NIGHT. THE UPPER TROUGH TO OUR
WEST PROGGED TO SPLIT INTO TWO PIECES. THE NRN PIECE IS PROGGED TO
GET CAUGHT UP WITH A SHORT WAVE TROUGH MOVING ACROSS THE NRN
PLAINS...AND AS IT DOES IT BRINGS THE LAST BIT OF LIFT TO THE
AREA...MAINLY ERN ZONES WHERE ONE LAST ROUND OF PRECIP IS MOST
LIKELY. PREVIOUS IDEA OF SLIGHT CHANCE WEST WITH A RAIN-SNOW MIX
AND CHANCE POPS EAST WITH ALL RAIN STILL LOOK FINE. AS THAT TROUGH
EXITS A COLD FRONT WILL SWEEP THROUGH THE FCST AREA EARLY SUNDAY.
MEANWHILE...THE SRN SPLIT OF THE UPPER TROUGH WILL SAG SWD OVER
NWRN MEXICO BY MIDDAY SUNDAY AND FURTHER SOUTH TO SRN BAJA CALIF
BY MIDDAY MONDAY. THE LINGERING UPPER TROUGH EXTENDING BETWEEN THE
TWO SPLITS ON SUNDAY COMBINED WITH THE COLD FRONTAL PASSAGE
COULD...ALTHOUGH UNLIKELY...BRING A FEW LIGHT SHOWERS TO THE
AREA. WILL KEEP PRECIP MENTION OUT OF SUNDAYS FCST. THIS SRN LOW
WILL THEN LOSE ITS INFLUENCE ON THE FCST AREA...EVENTUALLY
EJECTING EWD ACROSS NRN MEXICO AND THE TEXAS GULF COAST.

THE REMAINDER OF THE FCST LOOKS RATHER BENIGN WITH UPPER FLOW
BECOMING INCREASINGLY AMPLIFIED AS AN UPPER RIDGE BUILDS OVER THE
WRN CONUS. ONLY COLD FRONTAL PASSAGE LOOKING TO BE TOWARD
WEDNESDAY. BEFORE THEN TEMPS PEAK IN THE 60S THEN DROP BACK TOWARD
SEASONAL NORMS TO ROUND OUT THE WEEK.

526 AM CST FRI JAN 30 2015

.AVIATION...
VFR CLOUD DECKS WILL GRADUALLY DETERIORATE TO MVFR CRITERIA
THROUGHOUT THE TAF PERIOD...DUE AN UPPER LEVEL DISTURBANCE
APPROACHING THE REGION FROM THE WEST. THERE ARE HINTS OF DECKS
DROPPING TO IFR CONDITIONS AT KLBB AND KPVW...JUST BEYOND THIS TAF
CYCLE. WIDESPREAD -RA WILL COMMENCE LATE THIS EVENING INTO
TONIGHT...WITH THE POTENTIAL FOR A -RA/-SN MIX OCCURRING MORE SO
AT KLBB AND KPVW. WILL KEEP ONLY A -RA MENTION FOR NOW AS -SN WILL
LIKELY BE INTERMITTENT...BUT WILL OF COURSE AMEND AS NECESSARY.

&&

.PREV DISCUSSION... /ISSUED 351 AM CST FRI JAN 30 2015/

SHORT TERM...
MAIN FOCUS IN THE SHORT TERM PERIOD CONTINUES TO BE INCREASING
CHANCES FOR PRECIP...AS AN UA LOW CONTINUES TO SLOWLY TRANSLATE EAST
JUST OFF THE COAST OF THE BAJA EARLY THIS MORNING. THIS SYSTEM HAS
PROMOTED SW FLOW ALOFT TO DOMINATE ACROSS THE REGION AND THUS STREAM
A PLUME OF PACIFIC MOISTURE ACROSS THE REGION. THE RESULT IS SCT-OVC
MID-UPPER LEVEL CLOUDINESS WHICH WILL PREVAIL THROUGH TOMORROW.
LOOKING AT THE SFC...A SFC RIDGE WAS NOTED NE OF THE CWA EARLY THIS
MORNING THEREBY AIDING SFC WINDS TO BE OF AN E-NE COMPONENT PER 08Z
METARS. THIS SLIGHT UPSLOPE WIND COMPONENT HAS GARNERED PWATS TO
INCREASE TO AOA 0.50 INCHES SO FAR. RADAR TRENDS DISPLAYED LIGHT
ECHOES ACROSS THE PERMIAN BASIN AND FAR SW SOUTH PLAINS...WHICH IS
INDICATIVE OF A BIT OF LARGE SCALE ASCENT THAT HAS COMMENCED TO
SHIFT DOWNSTREAM OF THE AFOREMENTIONED UA LOW. WITH SFC TEMPS IN THE
LOWER 40S ACROSS THE SW SOUTH PLAINS...THE PRECIP TYPE IS LIQUID. IN
FACT...THE SEMINOLE METAR HAS INTERMITTENTLY REPORTED DRIZZLE.
MOST MODEL SOLUTIONS DO NOT HAVE A GOOD HANDLE ON THE CURRENT
LIGHT PRECIP...WITH THE EXCEPTION OF THE TTU WRF WHICH SHOWS THIS
LIGHT PRECIP ACTIVITY TO PERSIST FOR THE NEXT SEVERAL HOURS AND
PERHAPS SHIFT A BIT TO THE NORTH AND EAST...THOUGH WANING WITH
TIME.

LATER THIS MORNING INTO THIS AFTN...SFC WINDS WILL VEER TO THE E-SE
AS THE SFC RIDGE SLIDES SE FARTHER AWAY FROM THE REGION. THIS
UPSLOPE SFC REGIME WILL ONLY ENCOURAGE PWATS TO INCREASE INTO THE
0.75-0.85 INCH RANGE...WITH HIGHEST PWATS NOTED ACROSS THE SRN AND
SWRN ONES.  MODEL SOLUTIONS DO AGREE THAT LARGE SCALE ASCENT WILL
ALSO INCREASE A BIT /PARTICULARY ACROSS THE WRN ZONES/ WHILST TOP-
DOWN MOISTENING OCCURS. A WELL-DEFINED WARM NOSE BETWEEN 800 MB-750
MB AND SFC TEMPS WARMING INTO THE MIDDLE TO UPPER 30S WILL PROMOTE
MORE OF A WINTRY MIX /RAIN AND SNOW/ ACROSS THE WRN ZONES VERSUS
LIQUID RAINFALL ELSEWHERE. THIS EVENING INTO TONIGHT...BOTH PWATS
/0.75-1.00 INCH/ AND UL SUPPORT WILL BE MAXIMIZED DURING THIS PERIOD
AS THE UA LOW NEARS NWRN OLD MEXICO. TEMPS ALOFT WILL COOL
ESPECIALLY ACROSS THE FAR SW TX PANHANDLE AND NW SOUTH
PLAINS...HENCE RESULTING IN CHANCES OF SNOWFALL. MODEL SOUNDINGS
INDICATE MORE OF A RAIN AND SNOW MIX ACROSS MOST OF THE CAPROCK AND
RAINFALL OFF THE CAPROCK DURING THE SAID TIME-PERIOD. IT IS
INTERESTING TO NOTE THAT NATIONAL SNOWFALL MODELS AND EVEN THE USUAL
BULLISH GFS MODEL HAVE BACKED OFF ON THE /WET/ SNOWFALL
ACCUMULATION...BY SHOWING 1-2 INCH ACCUMULATIONS OCCURRING ACROSS
THE NW SOUTH PLAINS. THE NAM ON THE OTHER HAND IS A BIT MORE
AGGRESSIVE WITH 1-4 INCHES. HAVE GONE AHEAD AND TAPERED DOWN SNOWFALL
AMOUNTS A BIT...LEANING MORE SO TOWARDS 1-3 INCHES ACROSS THE NW
SOUTH PLAINS. AS SUCH...WINTER WEATHER HIGHLIGHTS BEYOND THE SPECIAL
WEATHER STATEMENT MAY BE WARRANTED...BUT WILL LET THE NEXT FEW
SHIFTS SEE IF RADAR TRENDS DO INDEED SHOW ACCUMULATING SNOWFALL.
TOMORROW...PRECIP WILL BE ONGOING BUT WILL BE SLOWLY SHIFTING FROM
WEST TO EAST. TEMPS WARMING ALOFT AND A SOME DRYING OCCURRING IN THE
MID-UPPER LEVELS WILL CAUSE THE PRECIP TYPE TO BE ALL LIQUID BY LATE
AFTN ACROSS MOST OF THE AREA /COULD STILL SEE A RAIN AND SNOW MIX
ACROSS THE NW ZONES/.

PER 08Z METARS...TEMPS ARE IN THE LOWER 30S ACROSS THE NW SOUTH
PLAINS TO THE LOWER 40S ELSEWHERE. WITH CONTINUED MID-UPPER LEVEL
CLOUD COVER /AND LOW CLOUDS DEVELOPING THIS EVENING/...TEMPS WILL
LIKELY NOT WARM MUCH THAN WHAT IT IS THIS MORNING. OVERNIGHT LOWS
WILL FALL TO THE UPPER 20S ACROSS THE NW TO THE UPPER 30S
SE...FOLLOWED BY HIGHS IN THE 40S TOMORROW.

LONG TERM...
PRECIP EVENT TO WIND DOWN SATURDAY NIGHT. THE UPPER TROUGH TO OUR
WEST PROGGED TO SPLIT INTO TWO PIECES. THE NRN PIECE IS PROGGED TO
GET CAUGHT UP WITH A SHORT WAVE TROUGH MOVING ACROSS THE NRN
PLAINS...AND AS IT DOES IT BRINGS THE LAST BIT OF LIFT TO THE
AREA...MAINLY ERN ZONES WHERE ONE LAST ROUND OF PRECIP IS MOST
LIKELY. PREVIOUS IDEA OF SLIGHT CHANCE WEST WITH A RAIN-SNOW MIX
AND CHANCE POPS EAST WITH ALL RAIN STILL LOOK FINE. AS THAT TROUGH
EXITS A COLD FRONT WILL SWEEP THROUGH THE FCST AREA EARLY SUNDAY.
MEANWHILE...THE SRN SPLIT OF THE UPPER TROUGH WILL SAG SWD OVER
NWRN MEXICO BY MIDDAY SUNDAY AND FURTHER SOUTH TO SRN BAJA CALIF
BY MIDDAY MONDAY. THE LINGERING UPPER TROUGH EXTENDING BETWEEN THE
TWO SPLITS ON SUNDAY COMBINED WITH THE COLD FRONTAL PASSAGE
COULD...ALTHOUGH UNLIKELY...BRING A FEW LIGHT SHOWERS TO THE
AREA. WILL KEEP PRECIP MENTION OUT OF SUNDAYS FCST. THIS SRN LOW
WILL THEN LOSE ITS INFLUENCE ON THE FCST AREA...EVENTUALLY
EJECTING EWD ACROSS NRN MEXICO AND THE TEXAS GULF COAST.

THE REMAINDER OF THE FCST LOOKS RATHER BENIGN WITH UPPER FLOW
BECOMING INCREASINGLY AMPLIFIED AS AN UPPER RIDGE BUILDS OVER THE
WRN CONUS. ONLY COLD FRONTAL PASSAGE LOOKING TO BE TOWARD
WEDNESDAY. BEFORE THEN TEMPS PEAK IN THE 60S THEN DROP BACK TOWARD
SEASONAL NORMS TO ROUND OUT THE WEEK.

SHORT TERM...
A MOISTURE LADEN UPPER LOW OFF BAJA LATE THIS AFTERNOON WILL MOVE
SLOWLY INTO THE MOJAVE DESERT FRIDAY AFTERNOON. AN UPPER LEVEL HIGH
PRESSURE RIDGE AXIS PASSING OVERHEAD TONIGHT WILL EDGE EAST FRIDAY
WITH DEEPENING MOISTURE AND INCREASING UPWARDS FORCING WORKING
THROUGH WESTERN INTO CENTRAL ZONES DURING THE DAY. A NOTABLE DRY
LAYER BELOW 750 MILLIBARS WILL BE IN PLACE WITH A TOP-DOWN
MOISTENING PROCESS EXPECTED TO LEAD TO PRECIPITATION SPREADING WEST
TO EAST ON FRIDAY...THOUGH EXISTENCE OF THIS LAYER ADDS CONSIDERABLE
UNCERTAINTY TO TIMING OF PRECIPITATION ONSET AND PRECIPITATION
AMOUNTS AS WE HAVE SEEN MANY TIMES PREVIOUSLY THIS WINTER. SHOWERS
ALREADY APPROACHING THE RIO GRANDE VALLEY IN FAR WEST TEXAS WILL
MOVE CLOSER OVERNIGHT AND NOT IMPROBABLE THAT LIGHT SHOWERS MAY
SPREAD INTO WESTERN AREAS. A COOL SURFACE HIGH PRESSURE RIDGE WILL
JUT SOUTHWARD THROUGH THE AREA WITH CENTER TO OUR NORTHEAST. LOW
LEVEL FLOW EXPECTED TO GRADUALLY VEER TO THE SOUTHEAST. NOT A VERY
COLD SURFACE RIDGE BY ANY MEANS FOR LATE JANUARY...AND THERMAL
PROFILES FOR CENTRAL AND EASTERN AREAS THROUGH FRIDAY CONTINUE TO
FAVOR LIQUID PRECIPITATION. DYNAMIC COOLING IS EXPECTED TO DRAW THE
THERMAL PROFILE COLD ENOUGH TO FAVOR MAINLY SNOW FRIDAY FOR WESTERN
BORDER...WITH A PHASE TRANSITION LIKELY REMAINING ACROSS WESTERN
COUNTIES THOUGH A BRIEF SLEET OR SNOW SHOWER CENTRAL ZONES ALSO NOT
ENTIRELY OUT OF THE QUESTION. STEADIER PRECIPITATION SHOULD
GRADUALLY TAKE OVER WESTERN AREAS ON FRIDAY AND MAY LEAD TO MOSTLY
UNDER 1 INCH ACCUMULATIONS OF WET SNOW NORTHWEST BORDER WITH OUTSIDE
RISK OF MAYBE ANOTHER INCH. BETTER CHANCES WILL EXPAND THROUGH THE
AREA FRIDAY NIGHT. FEW SIGNIFICANT CHANGES FROM THE PREVIOUS
FORECAST FOR THIS GO-AROUND. RMCQUEEN

LONG TERM...
ONLY MINOR CHANGES WERE MADE TO THE CURRENT FORECAST OF THIS
WEEKENDS PRECIPITATION SYSTEM. A LARGE PLUME OF SUBTROPICAL MOISTURE
WAS OBSERVED ON WATER VAPOR IMAGERY SPREAD OVER THE SOUTHWESTERN US
INTO WEST TEXAS. ALTHOUGH MID AND UPPER LEVELS WILL BE MOIST THROUGH
TOMORROW...LOW LEVELS WILL BE SLOW TO MOISTEN UP OFF THE CAPROCK
WITH SHORT WAVE RIDGING MOVING OVER THE AREA. DEEP MOIST ISENTROPIC
UPGLIDE WILL MANIFEST ITSELF FRIDAY NIGHT INTO SATURDAY MORNING AND
EXPECT THE BULK OF PRECIPITATION TO FALL DURING THIS TIME PERIOD.
DOWNGLIDE WILL BEGIN TO WORK ITS WAY IN FROM THE NORTH AT THE LOWEST
LEVELS AS EARLY AS SATURDAY AFTERNOON. PRECIPITATION WILL BE QUICK
TO END SATURDAY EVENING AS DRY NORTHWEST FLOW AND LARGE SCALE
SUBSIDENCE AS A NORTHERN STREAM TROUGH AXIS MOVES INTO THE REGION.

CONFIDENCE IS INCREASING IN MOSTLY RAIN FOR AREAS OFF THE CAPROCK
AND THE SOUTH PLAINS. LATEST MODEL RUNS HAVE TRENDED WARMER UNDER
VERY STRONG LOW LEVEL WARM AIR ADVECTION FRIDAY NIGHT. THE GREATEST
SNOW THREAT WILL BE ACROSS THE SOUTHWESTERN TEXAS PANHANDLE WHERE
WEAKER WAA WILL BE SEEN. SNOW TOTALS UP TO FOUR INCHES WOULD BE
LIKELY AND MOSTLY ON GRASSY AREAS WITH SURFACE TEMPERATURES AROUND
-2 TO 0C. A STRONG COLD FRONT WILL PLOW THROUGH ON SUNDAY DIPPING
TEMPERATURES BELOW SEASONAL AVERAGES BUT WILL BE SHORT LIVED. LEE
TROUGHING WILL RETURN NEXT WEEK UNDER DRY NORTHWEST FLOW. THERE MAY
BE ANOTHER INTERRUPTION TO THE WARMUP ON WEDNESDAY WITH ANOTHER COLD
FRONT AND AGAIN LATE NEXT WEEK.

WAS OBSERVED ON WATER VAPOR IMAGERY SPREAD OVER THE SOUTHWESTERN US
INTO WEST TEXAS. ALTHOUGH MID AND UPPER LEVELS WILL BE MOIST THROUGH
TOMORROW...LOW LEVELS WILL BE SLOW TO MOISTEN UP OFF THE CAPROCK
WITH SHORT WAVE RIDGING MOVING OVER THE AREA. DEEP MOIST ISENTROPIC
UPGLIDE WILL MANIFEST ITSELF FRIDAY NIGHT INTO SATURDAY MORNING AND
EXPECT THE BULK OF PRECIPITATION TO FALL DURING THIS TIME PERIOD.
DOWNGLIDE WILL BEGIN TO WORK ITS WAY IN FROM THE NORTH AT THE LOWEST
LEVELS AS EARLY AS SATURDAY AFTERNOON. PRECIPITATION WILL BE QUICK
TO END SATURDAY EVENING AS DRY NORTHWEST FLOW AND LARGE SCALE
SUBSIDENCE AS A NORTHERN STREAM TROUGH AXIS MOVES INTO THE REGION.

CONFIDENCE IS INCREASING IN MOSTLY RAIN FOR AREAS OFF THE CAPROCK
AND THE SOUTH PLAINS. LATEST MODEL RUNS HAVE TRENDED WARMER UNDER
VERY STRONG LOW LEVEL WARM AIR ADVECTION FRIDAY NIGHT. THE GREATEST
SNOW THREAT WILL BE ACROSS THE SOUTHWESTERN TEXAS PANHANDLE WHERE
WEAKER WAA WILL BE SEEN. SNOW TOTALS UP TO FOUR INCHES WOULD BE
LIKELY AND MOSTLY ON GRASSY AREAS WITH SURFACE TEMPERATURES AROUND
-2 TO 0C. A STRONG COLD FRONT WILL PLOW THROUGH ON SUNDAY DIPPING
TEMPERATURES BELOW SEASONAL AVERAGES BUT WILL BE SHORT LIVED. LEE
TROUGHING WILL RETURN NEXT WEEK UNDER DRY NORTHWEST FLOW. THERE MAY
BE ANOTHER INTERRUPTION TO THE WARMUP ON WEDNESDAY WITH ANOTHER COLD
FRONT AND AGAIN LATE NEXT WEEK.

NATIONAL WEATHER SERVICE LUBBOCK TX
1141 PM CST WED JAN 28 2015

.AVIATION...
VFR CONDITIONS EXPECTED THE NEXT 24 HOURS. LIGHT WINDS WILL VEER
NORTHERLY OVERNIGHT IN WAKE OF A COLD FRONT AND BECOME BREEZY BY
EARLY THURSDAY MORNING...INCREASING TO 15-20 KNOTS WITH GUSTS TO
25-30 KNOTS. MID AND HIGH CLOUDS WILL CONTINUE TO INCREASE THROUGH
THE PERIOD...BUT ANY SUB-VFR CEILINGS AND PRECIPITATION SHOULD
REMAIN OFF TO THE SOUTHWEST THROUGH 06Z FRIDAY.

&&

PREV DISCUSSION... /ISSUED 227 PM CST WED JAN 28 2015/

SHORT TERM...
WE ARE IN THE MIDST OF AN ANOTHER UNSEASONABLY WARM LATE JANUARY DAY
WITH 1930Z TEMPERATURES MOSTLY IN THE 70S...EVEN A FEW LOWER 80S
AROUND CHILDRESS AND PADUCAH. IN ADDITION TO THE WARMTH...BREEZY
WESTERLY WINDS /GENERALLY SUSTAINED IN THE 15-25 MPH RANGE/ HAVE
DEVELOPED THIS AFTERNOON THANKS TO A TIGHTENING PRESSURE GRADIENT
SOUTH OF A SHORTWAVE MOVING THROUGH THE CENTRAL PLAINS. THE WINDS
WILL DROP OFF THIS EVENING AS THE PRESSURE GRADIENT WEAKENS AND
THERMALLY DRIVEN MIXING CONCLUDES. A COLD FRONT WILL THEN FOLLOW
AFTER MIDNIGHT WITH THE WINDS SWINGING AROUND TO THE NORTH. THESE
NORTHERLY WINDS WILL BECOME BREEZY /SUSTAINED AT 15-25 MPH/ THROUGH
MUCH OF THURSDAY AS THE PRESSURE GRADIENT TIGHTENS AGAIN AND COLDER
AIR ADVECTS INTO WEST TEXAS. THIS FRONT WILL BRING AN END TO THE
NEAR RECORD TO RECORD TEMPERATURES OF LATE...THOUGH READINGS SHOULD
STILL MAKE IT UP TO AROUND AVERAGE LEVELS THURSDAY AFTERNOON.
ADDITIONALLY...HIGH AND MIDDLE LEVEL CLOUDS WILL THICKEN THROUGH THE
DAY AS OUR NEXT STORM SYSTEM OF CONSEQUENCE BEGINS TO APPROACH FROM
THE SOUTHWEST...THOUGH ANY PRECIPITATION SHOULD HOLD OFF UNTIL AFTER
00Z.

LONG TERM...
FORECAST SYSTEM TO END THE WEEK STILL LOOKS TO END OUR SEASONABLY
WARM TEMPERATURES AND LEAD US INTO A BRIEF WET PERIOD. TOP DOWN
MOISTENING WILL BEGIN AS EARLY AS THURSDAY MORNING WITH EXTENSIVE
CLOUD COVER SPREADING OVER THE REGION. THE UPPER LOW CURRENTLY OFF
THE CALIFORNIA COAST IS FORECAST TO DIP A LITTLE FARTHER SOUTH
THAN PREVIOUSLY FORECAST SHIFTING SOME OF THE BEST LARGE SCALE
LIFT TO THE SOUTH OF THE AREA. THE BEST LIFT STILL LOOKS TO BE
FRIDAY NIGHT INTO SATURDAY. MOIST ISENTROPIC UPGLIDE WILL RAMP UP
AS EARLY AS FRIDAY MORNING WITH DEEP ISENTROPIC LIFT BY FRIDAY
NIGHT. WITH THE UPPER LOW NOT MOVING QUICKLY ONCE IN THE SOUTHWEST
US...PERSISTENT MOIST ISENTROPIC UPGLIDE WILL PERSIST THROUGH AT
LEAST SATURDAY EVENING. AREAS OFF THE CAPROCK WILL BE SLOWEST IN
SATURATING THE COLUMN. THE SREF LOOKS TO HAVE A GOOD HANDLE ON
THIS DELAYING THE ONSET OF PRECIPITATION UNTIL AFTER 00Z SATURDAY
FOR THESE AREAS.

PRECIPITATION PHASE REMAINS TRICKY WITH THE LATEST FORECAST
ITERATION. MOSTLY RAIN IS STILL EXPECTED OFF THE CAPROCK ALTHOUGH
A WET MIX OF RAIN AND SNOW LOOKS LIKELY ON THE CAPROCK. NEAR
SURFACE TEMPERATURES WILL BE CLOSE ENOUGH THAT PRECIPITATION PHASE
COULD GO EITHER WAY BETWEEN RAIN AND SNOW ON THE CAPROCK. THE
SOUTHWESTERN PANHANDLE HAS THE BEST CHANCE OF ACCUMULATING
SNOWFALL AS USUAL. MODELS ARE EERILY SIMILAR IN THEIR PLACEMENT OF
SNOWFALL IN THE SOUTHWESTERN PANHANDLE. AMOUNTS ARE NOT TOO VARIED
EITHER BUT SREF PLUMES STILL SHOW AN EXTREMELY LARGE RANGE OF
SNOWFALL AMOUNTS. DRY SLOTTING MAY BE A FORMIDABLE FORCE AS EARLY
AS SATURDAY AFTERNOON PREMATURELY SHUTTING DOWN PRECIPITATION. BUT
NORTHWEST FLOW ENTERING THE REGION ON SUNDAY WILL PERMANENTLY END
PRECIPITATION.

543 PM CST WED JAN 28 2015

.AVIATION...
VFR CONDITIONS TO PREVAIL THROUGH THE PERIOD. BREEZY
WEST/NORTHWEST WINDS WILL DECREASE BELOW 10 KNOTS THIS
EVENING...BEFORE INCREASING TO 15-20 KNOTS FROM THE
NORTH/NORTHEAST BY EARLY THURSDAY MORNING BEHIND A COLD FRONT SET
TO COME THROUGH OVERNIGHT. GUSTS TO 25-30 KNOTS WILL BE POSSIBLE
AT THIS TIME AS MID CLOUDS BEGIN TO INCREASE UNDERNEATH CONTINUED
CIRRUS.

&&

.PREV DISCUSSION... /ISSUED 227 PM CST WED JAN 28 2015/

SHORT TERM...
WE ARE IN THE MIDST OF AN ANOTHER UNSEASONABLY WARM LATE JANUARY DAY
WITH 1930Z TEMPERATURES MOSTLY IN THE 70S...EVEN A FEW LOWER 80S
AROUND CHILDRESS AND PADUCAH. IN ADDITION TO THE WARMTH...BREEZY
WESTERLY WINDS /GENERALLY SUSTAINED IN THE 15-25 MPH RANGE/ HAVE
DEVELOPED THIS AFTERNOON THANKS TO A TIGHTENING PRESSURE GRADIENT
SOUTH OF A SHORTWAVE MOVING THROUGH THE CENTRAL PLAINS. THE WINDS
WILL DROP OFF THIS EVENING AS THE PRESSURE GRADIENT WEAKENS AND
THERMALLY DRIVEN MIXING CONCLUDES. A COLD FRONT WILL THEN FOLLOW
AFTER MIDNIGHT WITH THE WINDS SWINGING AROUND TO THE NORTH. THESE
NORTHERLY WINDS WILL BECOME BREEZY /SUSTAINED AT 15-25 MPH/ THROUGH
MUCH OF THURSDAY AS THE PRESSURE GRADIENT TIGHTENS AGAIN AND COLDER
AIR ADVECTS INTO WEST TEXAS. THIS FRONT WILL BRING AN END TO THE
NEAR RECORD TO RECORD TEMPERATURES OF LATE...THOUGH READINGS SHOULD
STILL MAKE IT UP TO AROUND AVERAGE LEVELS THURSDAY AFTERNOON.
ADDITIONALLY...HIGH AND MIDDLE LEVEL CLOUDS WILL THICKEN THROUGH THE
DAY AS OUR NEXT STORM SYSTEM OF CONSEQUENCE BEGINS TO APPROACH FROM
THE SOUTHWEST...THOUGH ANY PRECIPITATION SHOULD HOLD OFF UNTIL AFTER
00Z.

LONG TERM...
FORECAST SYSTEM TO END THE WEEK STILL LOOKS TO END OUR SEASONABLY
WARM TEMPERATURES AND LEAD US INTO A BRIEF WET PERIOD. TOP DOWN
MOISTENING WILL BEGIN AS EARLY AS THURSDAY MORNING WITH EXTENSIVE
CLOUD COVER SPREADING OVER THE REGION. THE UPPER LOW CURRENTLY OFF
THE CALIFORNIA COAST IS FORECAST TO DIP A LITTLE FARTHER SOUTH
THAN PREVIOUSLY FORECAST SHIFTING SOME OF THE BEST LARGE SCALE
LIFT TO THE SOUTH OF THE AREA. THE BEST LIFT STILL LOOKS TO BE
FRIDAY NIGHT INTO SATURDAY. MOIST ISENTROPIC UPGLIDE WILL RAMP UP
AS EARLY AS FRIDAY MORNING WITH DEEP ISENTROPIC LIFT BY FRIDAY
NIGHT. WITH THE UPPER LOW NOT MOVING QUICKLY ONCE IN THE SOUTHWEST
US...PERSISTENT MOIST ISENTROPIC UPGLIDE WILL PERSIST THROUGH AT
LEAST SATURDAY EVENING. AREAS OFF THE CAPROCK WILL BE SLOWEST IN
SATURATING THE COLUMN. THE SREF LOOKS TO HAVE A GOOD HANDLE ON
THIS DELAYING THE ONSET OF PRECIPITATION UNTIL AFTER 00Z SATURDAY
FOR THESE AREAS.

PRECIPITATION PHASE REMAINS TRICKY WITH THE LATEST FORECAST
ITERATION. MOSTLY RAIN IS STILL EXPECTED OFF THE CAPROCK ALTHOUGH
A WET MIX OF RAIN AND SNOW LOOKS LIKELY ON THE CAPROCK. NEAR
SURFACE TEMPERATURES WILL BE CLOSE ENOUGH THAT PRECIPITATION PHASE
COULD GO EITHER WAY BETWEEN RAIN AND SNOW ON THE CAPROCK. THE
SOUTHWESTERN PANHANDLE HAS THE BEST CHANCE OF ACCUMULATING
SNOWFALL AS USUAL. MODELS ARE EERILY SIMILAR IN THEIR PLACEMENT OF
SNOWFALL IN THE SOUTHWESTERN PANHANDLE. AMOUNTS ARE NOT TOO VARIED
EITHER BUT SREF PLUMES STILL SHOW AN EXTREMELY LARGE RANGE OF
SNOWFALL AMOUNTS. DRY SLOTTING MAY BE A FORMIDABLE FORCE AS EARLY
AS SATURDAY AFTERNOON PREMATURELY SHUTTING DOWN PRECIPITATION. BUT
NORTHWEST FLOW ENTERING THE REGION ON SUNDAY WILL PERMANENTLY END
PRECIPITATION.

VFR CONDITIONS WILL PREVAIL FOR THE NEXT 24 HOURS. LIGHT S-SW
SURFACE WINDS WILL COME AROUND TO THE WEST EARLY WEDNESDAY
MORNING AND INCREASE AFTER DAYBREAK. THROUGH THE DAY A SURFACE
TROUGH WILL SLIDE ACROSS THE AREA AND MAINTAIN BREEZY CONDITIONS.
A WIND SHIFT TO THE NORTHWEST WILL WORK ACROSS THE AREA LATE IN
THE DAY.

PREV DISCUSSION... /ISSUED 247 PM CST TUE JAN 27 2015/

SHORT TERM...
RIDGING ACROSS THE AREA WILL QUICKLY TRANSITION TO
SOUTHWESTERLY FLOW ALOFT THIS EVENING AS AN UPPER LEVEL DISTURBANCE
TRANSLATES EASTWARD FROM NORTHERN NEVADA INTO THE CENTRAL PLAINS.
THIS WILL DRIVE ANOTHER DRY FRONT INTO THE REGION. AFTER A
PLEASANTLY COOL OVERNIGHT PERIOD...WESTERLY DOWNSLOPE WINDS WILL
HELP WARM THINGS UP ONCE AGAIN. AS GUIDANCE HAS BEEN
UNDERESTIMATING THE EFFECTS OF SUCH ADIABATIC WARMING AS OF
LATE...HAVE ELECTED TO INCREASE MAX TEMPS A FEW DEGREES FOR
WEDNESDAY AFTERNOON. OTHERWISE...A FAIRLY PLEASANT SHORT TERM IS
IN STORE.

LONG TERM...
A TROUGH IS STILL LOOKING LIKELY TO AFFECT THE REGION FROM FRIDAY
THROUGH SATURDAY. THE ATMOSPHERE WILL SATURATE FROM THE TOP DOWN
WITH THIS SYSTEM. UPPER LEVEL MOISTURE WILL ADVECT OVER THE REGION
AS EARLY AS THURSDAY UNDER ZONAL FLOW ALOFT. HOWEVER...AS THE FLOW
TRANSITIONS TO SHORTWAVE RIDGING THEN SOUTHWEST FLOW...DEEPER
MOISTURE WILL BE ALLOWED TO FLOW INTO THE AREA. INITIALLY ON FRIDAY
THE LOW LEVEL AIR WILL BE DRY WITH A SURFACE RIDGE STILL FLEXING ITS
MUSCLE OVER THE AREA. THIS WILL QUICKLY MOISTEN UP WITH AN INCREASE
IN MOIST ISENTROPIC LIFT. THE BEST LIFT WITH THIS SYSTEM WILL COME
OUT LATE FRIDAY THROUGH SATURDAY MORNING. DECENT LIFT WILL CONTINUE
THROUGH THE DAY ON SATURDAY UNTIL DRIER NORTHWEST DOWNSLOPING FLOW
MOVES IN LATE SATURDAY INTO EARLY SUNDAY. THE GFS STILL WANTS TO
PINCH OFF A CLOSED LOW OVER NORTHWESTERN MEXICO MOVING OUT EARLY
NEXT WEEK WHILE THE ECMWF STILL MOSTLY KEEPS A POSITIVELY TILTED
TROUGH. THE FORECAST WILL CONTINUE TO FAVOR THE ECMWF SOLUTION WHICH
IS MORE IN LINE WITH THE GFS ENSEMBLE MEAN.

PRECIPITATION TYPE IS STILL UNCERTAIN WHETHER SOME AREAS WILL SEE
ALL RAIN...ALL SNOW...OR A MIX OF RAIN AND SNOW. WITH A LACK OF A
COLD AIR INTRUSION AT THE SURFACE...MOST PRECIPITATION WILL LIKELY
BE RAIN OFF THE CAPROCK WITH A MIX ON THE CAPROCK AND MOSTLY SNOW IN
THE SOUTHWESTERN TEXAS PANHANDLE. IT IS ENTIRELY POSSIBLE THAT THE
SOUTHWEST PANHANDLE COULD EXPERIENCE SNOW THROUGHOUT OR NEARLY THE
ENTIRE EVENT. THE GFS IS BANKING ON THIS POSSIBILITY DEPICTING
NEARLY A FOOT OF SNOW IN THIS AREA. ALTHOUGH SURFACE TEMPERATURES
MAY BE CLOSE TO 0C FOR MUCH OF THE EVENT...ANALOG GUIDANCE DOES
SUGGEST AREAS ON THE CAPROCK COULD PICK UP A FEW INCHES OF SNOW WITH
GREATER VALUES IN THE SOUTHWEST PANHANDLE.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
534 PM CST TUE JAN 27 2015

.AVIATION...
VFR CONDITIONS WILL PREVAIL FOR THE NEXT 24 HOURS. LIGHT S-SW
SURFACE WINDS WILL COME AROUND TO THE WEST EARLY WEDNESDAY
MORNING AND INCREASE AFTER DAYBREAK. THROUGH THE DAY A SURFACE
TROUGH WILL SLIDE ACROSS THE AREA AND MAINTAIN BREEZY CONDITIONS.
A WIND SHIFT TO THE NORTHWEST WILL WORK ACROSS THE AREA LATE IN
THE DAY.

&&

.PREV DISCUSSION... /ISSUED 247 PM CST TUE JAN 27 2015/

SHORT TERM...
RIDGING ACROSS THE AREA WILL QUICKLY TRANSITION TO
SOUTHWESTERLY FLOW ALOFT THIS EVENING AS AN UPPER LEVEL DISTURBANCE
TRANSLATES EASTWARD FROM NORTHERN NEVADA INTO THE CENTRAL PLAINS.
THIS WILL DRIVE ANOTHER DRY FRONT INTO THE REGION. AFTER A
PLEASANTLY COOL OVERNIGHT PERIOD...WESTERLY DOWNSLOPE WINDS WILL
HELP WARM THINGS UP ONCE AGAIN. AS GUIDANCE HAS BEEN
UNDERESTIMATING THE EFFECTS OF SUCH ADIABATIC WARMING AS OF
LATE...HAVE ELECTED TO INCREASE MAX TEMPS A FEW DEGREES FOR
WEDNESDAY AFTERNOON. OTHERWISE...A FAIRLY PLEASANT SHORT TERM IS
IN STORE.

LONG TERM...
A TROUGH IS STILL LOOKING LIKELY TO AFFECT THE REGION FROM FRIDAY
THROUGH SATURDAY. THE ATMOSPHERE WILL SATURATE FROM THE TOP DOWN
WITH THIS SYSTEM. UPPER LEVEL MOISTURE WILL ADVECT OVER THE REGION
AS EARLY AS THURSDAY UNDER ZONAL FLOW ALOFT. HOWEVER...AS THE FLOW
TRANSITIONS TO SHORTWAVE RIDGING THEN SOUTHWEST FLOW...DEEPER
MOISTURE WILL BE ALLOWED TO FLOW INTO THE AREA. INITIALLY ON FRIDAY
THE LOW LEVEL AIR WILL BE DRY WITH A SURFACE RIDGE STILL FLEXING ITS
MUSCLE OVER THE AREA. THIS WILL QUICKLY MOISTEN UP WITH AN INCREASE
IN MOIST ISENTROPIC LIFT. THE BEST LIFT WITH THIS SYSTEM WILL COME
OUT LATE FRIDAY THROUGH SATURDAY MORNING. DECENT LIFT WILL CONTINUE
THROUGH THE DAY ON SATURDAY UNTIL DRIER NORTHWEST DOWNSLOPING FLOW
MOVES IN LATE SATURDAY INTO EARLY SUNDAY. THE GFS STILL WANTS TO
PINCH OFF A CLOSED LOW OVER NORTHWESTERN MEXICO MOVING OUT EARLY
NEXT WEEK WHILE THE ECMWF STILL MOSTLY KEEPS A POSITIVELY TILTED
TROUGH. THE FORECAST WILL CONTINUE TO FAVOR THE ECMWF SOLUTION WHICH
IS MORE IN LINE WITH THE GFS ENSEMBLE MEAN.

PRECIPITATION TYPE IS STILL UNCERTAIN WHETHER SOME AREAS WILL SEE
ALL RAIN...ALL SNOW...OR A MIX OF RAIN AND SNOW. WITH A LACK OF A
COLD AIR INTRUSION AT THE SURFACE...MOST PRECIPITATION WILL LIKELY
BE RAIN OFF THE CAPROCK WITH A MIX ON THE CAPROCK AND MOSTLY SNOW IN
THE SOUTHWESTERN TEXAS PANHANDLE. IT IS ENTIRELY POSSIBLE THAT THE
SOUTHWEST PANHANDLE COULD EXPERIENCE SNOW THROUGHOUT OR NEARLY THE
ENTIRE EVENT. THE GFS IS BANKING ON THIS POSSIBILITY DEPICTING
NEARLY A FOOT OF SNOW IN THIS AREA. ALTHOUGH SURFACE TEMPERATURES
MAY BE CLOSE TO 0C FOR MUCH OF THE EVENT...ANALOG GUIDANCE DOES
SUGGEST AREAS ON THE CAPROCK COULD PICK UP A FEW INCHES OF SNOW WITH
GREATER VALUES IN THE SOUTHWEST PANHANDLE.

AVIATION...
NARROW AND SHARP UPPER LEVEL HIGH PRESSURE RIDGE AXIS WILL
TRANSLATE OVERHEAD TONIGHT AND EARLY TUESDAY...PASSING TO THE EAST
TUESDAY AFTERNOON AS A WEAKENING IMPULSE LIFTS INTO THE CENTRAL
ROCKIES. SURFACE PRESSURES WILL FALL TO THE LEE OF THE ROCKIES
TUESDAY AFTERNOON...ALLOWING SURFACE FLOW TO BACK TO THE SOUTH-
SOUTHWEST THOUGH STILL WITH ONLY MODEST SPEEDS. VFR CONTINUING.

PREV DISCUSSION... /ISSUED 333 PM CST MON JAN 26 2015/

SHORT TERM...
A WARM DAY IS IN PROGRESS ACROSS THE SOUTH PLAINS AREA. SEVERAL
LOCATIONS IN THE EASTERN ROLLING PLAINS HAVE RISEN INTO THE UPPER
70S AT 2 PM PER THE WEST TEXAS MESONET...AND IT IS NOT OUT OF THE
QUESTION THAT WE COULD SEE A 80 DEGREE READING IN THAT AREA WHEN THE
FINAL TEMPS COME IN. SATELLITE IMAGERY THIS AFTERNOON SHOWS SOME NW
TO SE-ORIENTED BANDS OF CIRRUS STRETCHING FROM SRN CALIFORNIA TO
SOUTH TEXAS...AS SUBTROPICAL MOISTURE GETS PULLED NEWD IN THE
CIRCULATION AROUND AN UPPER LOW OFF THE BAJA COAST. THIS LOW WILL
WEAKEN AND LIFT N-NEWD TONIGHT AND TUESDAY...WHILE A SHORTWAVE RIDGE
SLIGHTLY AMPLIFIES DOWNSTREAM OVER WEST TEXAS. WE SHOULD SEE A FEW
BANDS OF HIGH CLOUDS ROTATE ACROSS THE REGION BUT OTHERWISE THE
WEATHER WILL BE QUIET AND MILD. LOW TEMPS TONIGHT SHOULD BE MAINLY
IN THE 30S...WITH SOME LOWER 40S OUT IN THE LOW ROLLING PLAINS. HIGH
TEMPS ON TUESDAY LOOK TO BE VERY SIMILAR TO TODAY...NAMELY MID TO
UPPER 60S ACROSS THE FAR SW TX PANHANDLE...TO MID TO UPPER 70S IN
THE ROLLING PLAINS. A SUBTLE SURFACE TROUGH SLIDING ACROSS THE AREA
WILL SHIFT WINDS TO THE NW THIS EVENING...THEN WILL GRADUALLY RETURN
TO THE SW BY TUESDAY AFTERNOON.

LONG TERM...
WEDNESDAY HIGH TEMPERATURES WILL BE WELL ABOVE NORMAL AS PREVIOUSLY
ADVERTISED WITH TEMPS IN THE 70S FOR MOST OF US...UPPER 60S IN OUR
FAR NORTHWESTERN COUNTIES. WEAK COLD FRONT ASSOCIATED WITH LOW
PRESSURE ACROSS THE MIDWEST GETS PUSHED SOUTH THROUGH WEST TEXAS
AS COLD AIR FILTERS IN FROM THE NORTH...WE`LL REMAIN DRY THURSDAY
WITH A RETURN TO MORE SEASONABLE TEMPS...OFF TO OUR WEST ENERGY
SPLITTING OFF NORTHERN JET MEANDERS SOUTH AND EAST WITH A FAIR
AMOUNT OF DISCREPANCIES BETWEEN THE ECMWF AND GFS...THE ECMWF
PUSHES THE ENERGY FARTHER SOUTH NOT ALLOWING FOR MUCH ORGANIZATION
EAST OF THE SACRAMENTO`S AND ULTIMATELY BECOMING MORE DIFFUSE AS
IT TRACKS EASTWARD THROUGH OLD MEXICO. BEFORE DOING SO
THOUGH...PACIFIC MOISTURE DOES SPREAD ACROSS OUR REGION AND A COLD
FRONT EXTENDING SOUTH FROM SURFACE LOW PRESSURE ASSOCIATED WITH
THE UPPER TROF IN THE NORTHERN JET MOVES ACROSS WEST TEXAS.
SURFACE TEMPERATURES WILL HOVER AROUND THE FREEZING MARK AND HAVE
PUT A MIX OF RAIN AND SNOW FOR THE OVERNIGHT AND EARLY MORNING
HOURS...AS OF THIS TIME THE COLD AIR DOES NOT SEEM DEEP ENOUGH TO
SUPPORT ANY ACCUMULATING SNOWFALL. HIGHEST RAINFALL TOTALS FOR THE
EVENT WOULD BE IN OUR SOUTHERN MOST COUNTIES WITH ANYWHERE TO 0.5"
TO AN 1.00" OF RAINFALL POSSIBLE FOR THAT AREA FROM FRIDAY THROUGH
SATURDAY. THE ECMWF HAS US DRYING OUT PAST T.SHORT TERM...

LONG TERM...

GFS KEEPS REMNANT UPPER LEVEL ENERGY TO OUR SOUTHWEST TO BRING
ANOTHER POTENTIAL FOR RAINFALL EARLY NEXT WEEK.

548 PM CST MON JAN 26 2015

.AVIATION...
NARROW AND SHARP UPPER LEVEL HIGH PRESSURE RIDGE AXIS WILL
TRANSLATE OVERHEAD TONIGHT AND EARLY TUESDAY...PASSING TO THE EAST
TUESDAY AFTERNOON AS A WEAKENING IMPULSE LIFTS INTO THE CENTRAL
ROCKIES. SURFACE PRESSURES WILL FALL TO THE LEE OF THE ROCKIES
TUESDAY AFTERNOON...ALLOWING SURFACE FLOW TO BACK TO THE SOUTH-
SOUTHWEST THOUGH STILL WITH ONLY MODEST SPEEDS. VFR CONTINUING.

.PREV DISCUSSION... /ISSUED 333 PM CST MON JAN 26 2015/

SHORT TERM...
A WARM DAY IS IN PROGRESS ACROSS THE SOUTH PLAINS AREA. SEVERAL
LOCATIONS IN THE EASTERN ROLLING PLAINS HAVE RISEN INTO THE UPPER
70S AT 2 PM PER THE WEST TEXAS MESONET...AND IT IS NOT OUT OF THE
QUESTION THAT WE COULD SEE A 80 DEGREE READING IN THAT AREA WHEN THE
FINAL TEMPS COME IN. SATELLITE IMAGERY THIS AFTERNOON SHOWS SOME NW
TO SE-ORIENTED BANDS OF CIRRUS STRETCHING FROM SRN CALIFORNIA TO
SOUTH TEXAS...AS SUBTROPICAL MOISTURE GETS PULLED NEWD IN THE
CIRCULATION AROUND AN UPPER LOW OFF THE BAJA COAST. THIS LOW WILL
WEAKEN AND LIFT N-NEWD TONIGHT AND TUESDAY...WHILE A SHORTWAVE RIDGE
SLIGHTLY AMPLIFIES DOWNSTREAM OVER WEST TEXAS. WE SHOULD SEE A FEW
BANDS OF HIGH CLOUDS ROTATE ACROSS THE REGION BUT OTHERWISE THE
WEATHER WILL BE QUIET AND MILD. LOW TEMPS TONIGHT SHOULD BE MAINLY
IN THE 30S...WITH SOME LOWER 40S OUT IN THE LOW ROLLING PLAINS. HIGH
TEMPS ON TUESDAY LOOK TO BE VERY SIMILAR TO TODAY...NAMELY MID TO
UPPER 60S ACROSS THE FAR SW TX PANHANDLE...TO MID TO UPPER 70S IN
THE ROLLING PLAINS. A SUBTLE SURFACE TROUGH SLIDING ACROSS THE AREA
WILL SHIFT WINDS TO THE NW THIS EVENING...THEN WILL GRADUALLY RETURN
TO THE SW BY TUESDAY AFTERNOON.

LONG TERM...
WEDNESDAY HIGH TEMPERATURES WILL BE WELL ABOVE NORMAL AS PREVIOUSLY
ADVERTISED WITH TEMPS IN THE 70S FOR MOST OF US...UPPER 60S IN OUR
FAR NORTHWESTERN COUNTIES. WEAK COLD FRONT ASSOCIATED WITH LOW
PRESSURE ACROSS THE MIDWEST GETS PUSHED SOUTH THROUGH WEST TEXAS
AS COLD AIR FILTERS IN FROM THE NORTH...WE`LL REMAIN DRY THURSDAY
WITH A RETURN TO MORE SEASONABLE TEMPS...OFF TO OUR WEST ENERGY
SPLITTING OFF NORTHERN JET MEANDERS SOUTH AND EAST WITH A FAIR
AMOUNT OF DISCREPANCIES BETWEEN THE ECMWF AND GFS...THE ECMWF
PUSHES THE ENERGY FARTHER SOUTH NOT ALLOWING FOR MUCH ORGANIZATION
EAST OF THE SACRAMENTO`S AND ULTIMATELY BECOMING MORE DIFFUSE AS
IT TRACKS EASTWARD THROUGH OLD MEXICO. BEFORE DOING SO
THOUGH...PACIFIC MOISTURE DOES SPREAD ACROSS OUR REGION AND A COLD
FRONT EXTENDING SOUTH FROM SURFACE LOW PRESSURE ASSOCIATED WITH
THE UPPER TROF IN THE NORTHERN JET MOVES ACROSS WEST TEXAS.
SURFACE TEMPERATURES WILL HOVER AROUND THE FREEZING MARK AND HAVE
PUT A MIX OF RAIN AND SNOW FOR THE OVERNIGHT AND EARLY MORNING
HOURS...AS OF THIS TIME THE COLD AIR DOES NOT SEEM DEEP ENOUGH TO
SUPPORT ANY ACCUMULATING SNOWFALL. HIGHEST RAINFALL TOTALS FOR THE
EVENT WOULD BE IN OUR SOUTHERN MOST COUNTIES WITH ANYWHERE TO 0.5"
TO AN 1.00" OF RAINFALL POSSIBLE FOR THAT AREA FROM FRIDAY THROUGH
SATURDAY. THE ECMWF HAS US DRYING OUT PAST T.SHORT TERM...

MINOR UPDATE TO NUDGE OUR HIGH TEMPS FOR THIS AFTERNOON UP A FEW
DEGREES. 1 PM WEST TEXAS MESONET OBS SHOW THAT MANY LOCATIONS HAVE
REACHED OR ARE WITHIN A DEGREE OF THEIR FORECAST HIGHS.

.PREV DISCUSSION... /ISSUED 1137 AM CST MON JAN 26 2015/

AVIATION...
VFR WITH STEADY W-NW WINDS AROUND 10 KNOTS.

PREV DISCUSSION... /ISSUED 333 AM CST MON JAN 26 2015/

SHORT TERM...
LONG WAVE RIDGE EXTENDING FROM THE PACIFIC NW TO THE RIO GRANDE WILL
MIGRATE SLOWLY EAST TODAY ACCOMPANIED BY UNSEASONABLY MILD AIR. MEAN
WESTERLY FLOW AT THE SURFACE WILL SERVE TO BOOST LL THICKNESSES
LOCALLY...SO HAVE EDGED MAX TEMPS CLOSER TO THE MILDER MAV NUMBERS.
MAV REMAINS FAVORED FOR MIN TEMPS IN THIS PATTERN AS THE MET HAS
PROVEN TOO COOL AS OF LATE.

LONG TERM...
MILD AND DRY CONDITIONS WILL CONTINUE THROUGH MID WEEK AS THE
UPPER LEVEL RIDGE MIGRATES EASTWARD ACROSS WEST TEXAS. WEAK FRONT
MOVING SOUTH INTO THE PANHANDLE WILL HAVE LITTLE EFFECT ON
TEMPERATURES AS DEEP DRY AIR AND DOWNSLOPE WARMING CONTRIBUTE TO
VERY WARM TEMPS FOR LATE JANUARY...ESP WEDNESDAY WITH 70S
EVERYWHERE EXCEPT THE SOUTHWEST PANHANDLE.

FRONT AND ASSOCIATED COOLER TEMPS WILL ARRIVE WED NIGHT...REVERSING
THE WARMING TREND AND KNOCKING BACK TEMPERATURES AROUND 10 DEGREES
THURSDAY FROM WEDNESDAY/S HIGHS. SHORTWAVE RIDGING AGAIN THURSDAY
WILL BE FOLLOWED BY SURGE OF SUBTROPICAL MOISTURE AND POSSIBLE
RAIN THURSDAY NIGHT INTO FRIDAY. BOTH ECM AND GFS ARE BULLISH
WITH THIS IDEA...AND GIVEN SIMILARITY OF SOLUTIONS AND PRESENCE OF
DEEPER MOISTURE MOVING NE AHEAD OF UPPER LOW/TROUGH ACROSS THE
GREAT BASIN THROUGH SRN CALIFORNIA. CONTINUED TREND OF UPPING
POPS FURTHER IN THIS TIME FRAME. DON`T THINK GFS HIGHER AMOUNTS
ARE NECESSARILY UNREASONABLE GIVEN PATTERN.

ALTHOUGH THERE ARE MODEL DIFFERENCES WITH NEXT FRONT WHICH WILL
MOVE SOUTH IN WAKE OF NORTHERN STREAM SHORTWAVE...THERE IS
AGREEMENT ON COLDER AIR SATURDAY...WHICH COULD CHANGE PRECIP. TO
SNOW OR A RAIN/SNOW MIX SATURDAY NIGHT/SUNDAY MORNING. A BREAK IN
THE ACTION LIKELY SUNDAY AS UPPER LOW HEADS SOUTH ALONG

TEMPERATURES HAVE WARMED WELL INTO THE 50S ACROSS THE SOUTH PLAINS
REGION THIS AFTERNOON...WITH LOCATIONS IN THE SOUTHEAST SOUTH PLAINS
AND ROLLING PLAINS BREACHING INTO THE 60S ON BREEZY NORTHWEST WINDS.
THIS WARMING TREND WILL CONTINUE ALOFT TONIGHT AS AN APPROACHING
WESTERN CONUS RIDGE BRINGS A TRANSITION TO ANTICYCLONIC FLOW IN WAKE
OF A STOUT UPPER DISTURBANCE PUSHING INTO THE TENNESSEE VALLEY. LOWS
TONIGHT SHOULD REMAIN IN THE 30S ON MOST OF THE CAPROCK AND MID 30S
TO LOW 40S IN THE ROLLING PLAINS.

WEAK SURFACE RIDGING IN THE LOWER ROCKIES WILL PROMOTE NORTHWEST
WINDS IN THE 10-15 MPH RANGE MONDAY AS AFOREMENTIONED RIDGING MOVES
OVERHEAD...BRINGING EVEN WARMER TEMPERATURES TO BEGIN THE FINAL WEEK
OF JANUARY. FULL INSOLATION AND H85 THERMAL RIDGING ACROSS THE HIGH
PLAINS WILL RESULT IN 10-20 DEGREE ABOVE NORMAL
TEMPERATURES...REACHING WELL INTO THE 60S ACROSS THE SOUTH PLAINS
WITH UPPER 60 TO LOW 70 DEGREE READINGS IN THE FAR SOUTHEAST
PANHANDLE AND ROLLING PLAINS.

LONG TERM...
.INCREASING CONFIDENCE IN PRECIPITATION CHANCES LATE IN THE
WEEK INTO NEXT WEEKEND...

THE FIRST PART OF THE WEEK WILL BE WARM AND DRY. TEMPERATURES
SHOULD PEAK WEDNESDAY AFTERNOON AS A WEAK SHORTWAVE SKIRTS WEST
TEXAS TO THE NORTH...TIGHTENING THE PRESSURE GRADIENT AND
RESULTING IN BREEZY...WESTERLY DOWNSLOPING WINDS. HIGHS SHOULD BE
IN THE 60S AND 70S BOTH TUESDAY AND WEDNESDAY. A COLD FRONT WILL
PASS THROUGH THE AREA WEDNESDAY NIGHT OR EARLY THURSDAY MORNING.
THURSDAY/S HIGHS SHOULD FALL BACK INTO THE 50S AND 60S AS WE SEE
INCREASING CLOUD COVER FROM THE WEST...DOWNSTREAM OF A UPPER LOW
DIGGING INTO AND CUTTING OFF ACROSS THE DESERT SOUTHWEST. MEDIUM-
RANGE GUIDANCE IS IN DECENT AGREEMENT THAT PRECIP CHANCES WILL
EXPAND FROM THE SOUTHWEST THURSDAY NIGHT AS ISENTROPIC UPGLIDE
DEVELOPS IN SWERLY MID-LVL FLOW ATOP LOW-LEVEL UPSLOPE FLOW.
FRIDAY INTO SATURDAY...THE UPPER LOW IS NOT EXPECTED TO MOVE A
WHOLE LOT...PERHAPS DRIFTING TO THE SOUTH OR SOUTHEAST. THIS
SHOULD ALLOW A STEADY STREAM OF MID-LVL MOISTURE NEWD ACROSS WEST
TEXAS AND KEEP US IN A COOL...CLOUDY AND MOIST PATTERN. THE BEST
PRECIP CHANCES AND HIGHEST PRECIP TOTALS MAY END UP TO OUR
SOUTH...BUT A BROAD AREA OF LIGHT TO MODERATE PRECIP LOOKS
INCREASINGLY LIKELY FOR THE SOUTH PLAINS AREA. POPS HAVE BEEN
RAISED INTO THE 40 TO 60 PERCENT RANGE. THERE IS STILL SOME
UNCERTAINTY REGARDING THE TRACK OF THE SYSTEM BEYOND
SATURDAY...IT COULD DRIFT FARTHER SOUTH OR SOUTHWEST...BRINGING A
DECREASE IN PRECIP CHANCES BY SUNDAY. OR IT COULD ADVANCE EAST
ACROSS NRN MX AND TX...WHICH COULD KEEP PRECIP CHANCES GOING INTO
EARLY NEXT WEEK. AS FOR TEMPS AND PRECIP TYPE...WE EXPECT TEMPS TO
REMAIN ABOVE FREEZING THROUGH THE DAY FRIDAY...BUT COULD DIP BELOW
FREEZING FOR MUCH OF THE AREA BY EARLY SATURDAY MORNING...WITH
COLDER TEMPS EXPECTED SAT NIGHT/SUN MORNING. THUS IT LOOKS LIKE
SNOW POTENTIAL COULD ENTER THE MIX EARLY SAT AND ESPECIALLY SAT
NIGHT IF THE PRECIP LINGERS...ALTHOUGH IT IS TOO EARLY TO TELL IF
TEMPS WILL BE COLD ENOUGH TO SUPPORT SIGNIFICANT ACCUMULATIONS.
