.PREV DISCUSSION... /ISSUED 300 PM CDT MON SEP 21 2009/
DISCUSSION...
A MAJOR PATTERN SHIFT IS CURRENTLY UNDERWAY ACROSS A LARGE PART OF
THE CENTRAL CONUS AS A STRONG EARLY SEASON CUTOFF LOW PRESSURE
CENTER CONTINUES TO CHURN ACROSS THE NORTHERN PLAINS. THE WELL
ADVERTISED COLD FRONT ACCOMPANYING THIS SYSTEM CONTINUES TO BEAR
DOWN ACROSS THE CENTRAL TX PANHANDLE EARLY THIS AFTERNOON WITH
BOUNDARY NOW MOVING THROUGH KLBB. A WEAK PRE-FRONTAL TROUGH HAS
NOW PUSHED THROUGH MUCH OF THE AREA WITH WEST-NORTHWESTERLY
DOWNSLOPE WINDS PREVAILING IN ITS WAKE. THIS HAS ALLOWED TEMPS TO
SOAR ONCE AGAIN THIS AFTERNOON WITH LATEST OBS SHOWING LOW TO MID
90S ACROSS MUCH OF THE AREA. BEST INSTABILITY THIS AFTERNOON
REMAINS WELL OFF TO THE EAST IN CLOSE PROXIMITY TO THE MAIN
MID-LEVEL THETA-E RIDGE ACROSS CENTRAL TX. KMAF RADAR SHOWING
SOME WEAK RETURNS ACROSS THE MARFA PLATEAU/LOWER TRANS PECOS.
ACTIVITY IS NOT EXPECTED TO BECOME TO ROBUST HOWEVER AS THE BEST
0-6KM SHEAR REMAINS WELL TO THE NORTH IN RESPONSE TO A DIGGING
MID-LEVEL JET MAX ACCOMPANYING THE MAIN POLAR VORTEX TO THE NORTH.
SURFACE COLD FRONT WILL PLOW THROUGH THE REGION TONIGHT LEADING TO
A STARK WIND SHIFT TOWARDS THE NORTH/NORTHEAST. SHORT TERM PROGS
ARE IN RELATIVELY GOOD AGREEMENT THAT A STRONG PRESSURE RISE
COUPLET WILL QUICKLY DESCEND ACROSS THE EASTERN NM HIGH PLAINS
FOLLOWING ITS PASSAGE...WHICH SHOULD RESULT IN THE STRONGEST
WINDS FROM THE SOUTHEAST NEW MEXICO PLAINS SOUTHWARD THROUGH THE
MARFA PLATEAU. HAVE DECIDED TO ISSUE A WIND ADVISORY FOR THESE
LOCATIONS IN ANTICIPATION OF THE STRONG ISALLOBARIC WIND RESPONSE.
WARNING CRITERIA WINDS WILL OCCUR ACROSS THE GUADALUPE PASS...AND
HAVE ALSO DECIDED TO ISSUE A HIGH WIND WARNING FOR THE DAVIS
MOUNTAINS ABOVE 6000 KFT. EXPECT STRONG WINDS TO PERSIST THROUGH
THE OVERNIGHT HOURS AND INTO THE EARLY MORNING BEFORE THE PRESSURE
GRADIENT SLOWLY BEGINS TO RELAX BY EARLY AFTERNOON. STRONG
ISENTROPIC LIFT ALONG THE 295-300K THETA SURFACES WILL HELP LEAD
TO SOME SHOWERS/ISOLATED THUNDER ACROSS THE AREA OVERNIGHT...AND
HAVE MAINTAINED THE HIGHEST POPS ACROSS THE EASTERN ZONES. BUFKIT
FORECAST SOUNDINGS STILL INDICATE SOME ELEVATED CAPE AND HAVE
DECIDED TO LEAVE AN ISO MENTION FOR THUNDER IN. REGARDING HIGHS
TOMORROW...MODEL GUIDANCE CONTINUES TO COME IN COOLER AND COOLER
WITH EACH SUCCESSIVE RUN. HAVE DECIDED TO FOLLOW THE COOLER MET
MOS NUMBERS AS IT APPEARS TO HAVE THE BEST HANDLE ON THE
SITUATION.
A COOL COUPLE OR MORNINGS EXPECTED BOTH WEDNESDAY THURSDAY AS
SURFACE HIGH PRESSURE NOSES INTO THE AREA. THIS SHOULD RESULT IN
RATHER WEAK SURFACE WINDS AND HAVE CONTINUED TO TREND LOWS DOWN
ACROSS THE BOARD. ONLY PROBLEM THAT IS READILY APPARENT IS THAT
SHORT TERM PROGS ARE STILL INDICATING SOME LOW-LEVEL MOISTURE
LINGERING AROUND WHICH MAY LEAD TO SLIGHTLY WARMER TEMPS THAN
CURRENTLY FORECAST. IN GENERAL...SUCCESSIVE SHORTWAVE TROUGHS
PASSING ACROSS THE REGION WILL LEAD TO CONTINUED SHOWER CHANCES
THROUGH THE WEEK.
EXTENDED (FRI-MON)...
MODELS HAVE COME INTO BETTER AGREEMENT DURING THE EXTENDED PERIOD
WITH THE 12Z GFS FARTHER EAST WITH THE PLACEMENT OF THE CENTRAL
PLAINS UPPER LEVEL LOW. THIS IS MORE IN LINE WITH THE ECMWF/CANADIAN
SOLUTION WHICH WOULD LEAD TO A GENERAL DRYING/WARMING TREND THROUGH
THE WEEKEND. ON FRIDAY HIGHER THETA E VALUES...UNSTABLE LI VALUES
AND SURFACE DEW POINTS IN THE LOW TO MID 50S SHOULD LEAD TO ISOLATED
DIURNALLY DRIVEN CONVECTION OVER THE HIGHER TERRAIN OF WEST TEXAS
AND SOUTHEAST NEW MEXICO. BY SATURDAY THE UPPER LEVEL LOW BEGINS TO
EJECT NORTHEAST TOWARD THE GREAT LAKES REGION AND AN UPPER LEVEL
RIDGE BEGINS TO MOVE INTO THE PACIFIC NORTHWEST AND GREAT BASIN
REGION. THIS WILL SET UP A BRIEF PERIOD OF NORTHWEST FLOW ALOFT
ACROSS THE REGION WHICH IS USUALLY CONDUCIVE TO CONVECTION ROLLING
IN FROM EASTERN NEW MEXICO OR THE TEXAS PANHANDLE. LOW
DEWPOINTS...MARGINAL INSTABILITY AND THE LACK OF A FORCING MECHANISM
ACROSS THE AFOREMENTIONED AREAS SHOULD LEAD TO MAINLY DRY
CONDITIONS. WE WILL INTRODUCE ISOLATED POPS ACROSS THE EXTREME
NORTHERN PERMIAN BASIN AND SOUTHEAST NEW MEXICO AS WELL AS OVER THE
MOUNTAINS ON SATURDAY. ON SUNDAY UPPER LEVEL RIDGING BUILDS IN FROM
THE WEST USHERING IN DRIER AIR AND SHUTTING OFF RAIN CHANCES ACROSS
MOST OF THE AREA. TEMPERATURES ARE EXPECTED TO BE ABOVE NORMAL
SAT-MON. AFTERNOON HIGHS WILL APPROACH THE UPPER 80S TO NEAR 90
ACROSS MUCH OF THE PERMIAN BASIN SUNDAY AS A LOW LEVEL THERMAL RIDGE
BUILDS IN FROM THE SOUTHWEST. UPPER LEVEL RIDGING WILL PERSIST
THROUGH EARLY NEXT WEEK CONTINUING THE DRY AND UNSEASONABLY WARM
CONDITIONS ACROSS THE AREA.

VISIBILITIES MAY BE BRIEFLY REDUCED TO AROUND 5 MILES IN BLOWING DUST...ESPECIALLY NEAR PLOWED FIELDS AND CONSTRUCTION SITES. MAINLY ISOLATED THUNDERSTORMS ARE EXPECTED ACROSS WEST TEXAS AND SOUTHEASTERN NEW MEXICO THIS AFTERNOON AND TONIGHT.
