.DISCUSSION...

SEE AVIATION DISCUSSION BELOW.

.AVIATION...

VISIBLE SATELLITE IMAGERY/SFC OBS SHOW MOST TERMINALS SOCKED IN
THIS AM...UNDER MVFR-LIFR CIGS/VISBYS. DON/T EXPECT THINGS TO
IMPROVE MUCH OVER THE NEXT 24 HOURS AS ISENTROPIC LIFT
CONTINUES...AND UPPER TROUGH CURRENTLY IN CHIHUAHUA PASSES TO THE
SOUTH. THIS FEATURE WILL OPEN UP A DIFLUENT ZONE ALOFT...BRINGING
SHRA FIRST INTO KMAF...AND THEN TO OTHER TERMINALS OVERNIGHT AS
SHOWERS WRAP AROUND THE TROUGH. LATEST NAM BRINGS IN THE HEAVIEST
SHRA AT 12-15Z...WHEN CIGS/VSBYS WILL RANGE FROM MVFR AT KCNM...TO
LIFR/VLIFR AT KMAF/KFST. BEGINNING AROUND 10Z...A COLD FRONT WILL
SHIFT/INCREASE SFC WINDS TO THE NORTH.

&&

.PREV DISCUSSION... /ISSUED 643 AM CST TUE JAN 8 2013/

A STRONG UPPER LEVEL STORM SYSTEM MOVING OVER THE AREA WEDNESDAY
LOOKS TO IMPART WINTER WEATHER TO LOCATIONS ALONG AND WEST OF A
GUADALUPE MOUNTAINS TO ALPINE TO BIG BEND LINE TONIGHT THROUGH
WEDNESDAY NIGHT. IN ADDITION...MODERATE TO HEAVY RAINFALL WILL BE
POSSIBLE OVER THE PERMIAN BASIN...WESTERN LOW ROLLING PLAINS AND
LOWER TRANS PECOS FOR THE SAME TIME FRAME.

A LARGE UPPER LOW TRAVERSING NORTHERN MEXICO THIS MORNING WILL
LIKELY RESULT IN A WIDE VARIETY OF PRECIPITATION ACROSS SOUTHEAST
NEW MEXICO AND WEST TEXAS THROUGH WEDNESDAY NIGHT.  THIS MORNING...
LOW LEVEL MOISTURE IS STEADILY FLOWING TOWARD THE REGION FROM THE
SOUTHEAST AS HEIGHT FALLS AHEAD OF THE SAID LOW BACK AND INCREASE
EASTERLY LOW LEVEL WINDS.  THESE WINDS AND THE INCREASE IN MOISTURE
WILL SERVE TO KEEP SURFACE TEMPERATURES WHERE THEY ARE THE NEXT FEW
HOURS...IF NOT INCREASE THEM.  OVER THE WESTERN AND NORTHERN CWA
THOUGH...SURFACE TEMPERATURES ARE IN THE 20S TO LOW 30S.  LIGHT
PRECIPITATION MAY BREAK OUT OVER PORTIONS OF THE GUADALUPE AND DAVIS
MOUNTAINS THIS MORNING...SOME OF WHICH COULD BE FREEZING DRIZZLE OR
RAIN.  IT APPEARS PRECIPITATION IS COMING ABOUT MORE SLOWLY THAN THE
MORE AGGRESSIVE MODELS...AND WILL BE VERY LIGHT IF IT OCCURS AT
ALL...SO WILL MAKE A MENTION IN THE HWO FOR NOW.  IT APPEARS SURFACE
TEMPERATURES RISE ABOVE FREEZING AROUND 08/15Z...SO THE THREAT FROM
FREEZING PRECIPITATION APPEARS TO BE SHORT LIVED FOR TODAY.  BY THIS
AFTERNOON...ASCENT AHEAD OF THE UPPER LOW WILL INCREASE ENOUGH FOR A
GOOD CHANCE OF LIGHT RAIN OVER THE PERMIAN BASIN...ALTHOUGH AN
ISOLATED RUMBLE OF THUNDER OR TWO COULD OCCUR AS MID LEVEL LAPSE
RATES STEEPEN DUE TO THE ONSET OF COLDER TEMPERATURES ALOFT.
RAINFALL AMOUNTS MAY BE ENHANCED A LITTLE...BUT ANY WEAK
THUNDERSTORMS SHOULD BE FEW AND FAR BETWEEN.  ALSO...RAIN MAY MIX
WITH SNOW OVER THE HIGHER ELEVATIONS OF THE DAVIS MOUNTAINS WHERE
COOLER TEMPERATURES ALOFT AND AT THE SURFACE WILL EXIST.  LITTLE
ACCUMULATIONS IS EXPECTED THOUGH.

PRECIPITATION WILL INCREASE ACROSS THE REGION TONIGHT AS THE UPPER
LOW NEARS.  ISOLATED THUNDERSTORMS WILL STILL BE POSSIBLE...BUT ALSO
DUE TO A MARKED INCREASE IN LIFT AHEAD OF A POTENT VORTICITY MAXIMA
SWINGING AROUND THE BASE OF THE UPPER LOW AND INTO THE REGION.
PWATS WILL INCREASE TO AROUND 0.75 INCH EAST...AND 0.5 INCH WEST.
THIS WILL BE SIGNIFICANT...ESPECIALLY OVER THE WEST WHERE THE COLUMN
COOLS DUE TO DYNAMIC COOLING.  WOULD HAVE CONSIDERED KEEPING THE
FREEZING RAIN INHERITED IN THE PREVIOUS FORECAST...BUT SURFACE
TEMPERATURES MAINLY STAY ABOVE FREEZING THROUGH THE EVENING.
HOWEVER....THE ATMOSPHERIC COLUMN WILL COOL...ALONG WITH SURFACE
TEMPERATURES...AS RAIN TRANSITIONS TO A BRIEF PERIOD OF SLEET...THEN
SNOW LATE TONIGHT AS ENHANCED LIFT WITHIN THE DENDRITIC SNOWFLAKE
GROWTH REGION AROUND -15C OCCURS WEST OF THE PECOS.  HAVE ISSUED A
WINTER STORM WATCH FOR TONIGHT INTO WEDNESDAY NIGHT SINCE THE
ENHANCED LIFT PERSISTS THROUGH THE DAY WEDNESDAY OVER THE WESTERN
CWA AND INTO WEDNESDAY NIGHT.  COLDER AIR WILL ALSO BEGIN TO FUNNEL
SOUTH INTO THE FORECAST AREA AROUND THE UPPER LOW...AND A SURFACE
LOW OVER SOUTHERN...THEN CENTRAL TEXAS.  PWATS WILL ALSO INCREASE TO
0.75 INCH OVER MUCH OF THE AREA DURING THE DAY WEDNESDAY...POSSIBLY
LEADING TO SIGNIFICANT SNOWFALL AMOUNTS.  A MIX OF RAIN AND SNOW
WILL BE POSSIBLE OVER SOUTHEAST NEW MEXICO WEDNESDAY AFTERNOON...IF
NOT ALL SNOW BY EARLY EVENING.  HAVE INCLUDED SOME LIGHT AMOUNTS FOR
NOW...BUT SOUTHEAST NEW MEXICO IN PARTICULAR COULD BE ADDED TO THE
WINTER STORM WATCH...OR WARNING LATER TODAY IF THE CURRENT TRENDS IN
THE MODELS HOLD UP.

IT APPEARS PRECIPITATION WILL FALL AS RAIN OVER THE PERMIAN BASIN
..WESTERN LOW ROLLING PLAINS AND LOWER TRANS PECOS SINCE LOW LEVEL
MOISTURE WILL INCREASE ENOUGH TO PREVENT TEMPERATURES FROM DROPPING
ENOUGH WITHIN THE ATMOSPHERIC COLUMN OR AT THE SURFACE.  THE MAIN
WINDOW OF OPPORTUNITY WILL BE TONIGHT THROUGH WEDNESDAY EVENING AS
THE UPPER LOW SKIRTS THE AREA.  MODERATE TO HEAVY RAINFALL COULD
YIELD ANYWHERE FROM 0.5 INCH NEAR THE PECOS RIVER TO NEAR 1.5 INCHES
OVER THE PERMIAN BASIN AND WESTERN LOW ROLLING PLAINS.  IT WILL BE
CHILLY AND RAW AREAWIDE TODAY...BUT IT WILL FEEL MUCH MORESO
TONIGHT...WEDNESDAY AND WEDNESDAY NIGHT AS THE DIURNAL TEMPERATURE
RANGE WILL BE SMALL.  TEMPERATURES WILL WARM SOMEWHAT THURSDAY AS
THE CUTOFF LOW FINALLY MOVES AWAY FROM THE REGION.   EVEN WARMER
TEMPERATURES ARE EXPECTED FRIDAY DUE TO INCREASED SOUTHWESTERLY
DOWNSLOPE WINDS AHEAD OF ANOTHER LARGE UPPER TROUGH OVER THE WESTERN
CONUS.  PRECIPITATION CHANCES DO NOT LOOK GOOD WITH THIS UA
TROUGH...BUT COLD AIR WILL DROP INTO THE AREA SATURDAY WITH ONLY
COLDER TEMPERATURES EXPECTED THROUGH THE REST OF THE FORECAST PERIOD
AS ADDITIONAL SHORTWAVE TROUGHS KEEP A LONGWAVE TROUGH OVER THE
CONUS INTO NEXT WEEK.
