AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE LUBBOCK TX
328 PM CDT TUE OCT 11 2011

.SHORT TERM...
LOW CLOUDS TOOK A WHILE TO BURN OFF THIS MORNING AND WHEN THEY DID
WE QUICKLY TRANSITIONED OVER TO A PRETTY GOOD CU FIELD OVER THE
AREA.  20Z SURFACE ANALYSIS SHOWS A SURFACE LOW CENTERED OVER THE
OKLAHOMA PANHANDLE WITH A BROAD TROF TRAILING OFF TO THE SOUTH THEN
SOUTHWEST ACROSS THE WESTERN PORTIONS OF THE SOUTH PLAINS.  THIS
TROF HAS BEEN TRYING TO SHARPEN UP A DRYLINE ACROSS THE AREA WITH
DEWPOINTS JUST EAST OF THE TROF AXIS IN THE MID TO UPPER 50S WITH
UPPER 30S TO NEAR 40 WEST OF THE AXIS.  LATEST SATELLITE LOOP SHOWS
SOME ENHANCED CUMULUS DEVELOPING SOUTH OF LUBBOCK INTO THE NORTHERN
PERMIAN BASIN...AND A FEW STORMS HAVE ALREADY STARTED TO DEVELOP
SOUTH OF MIDLAND.

W/V SATELLITE LOOP INDICATES THAT A STRONG JETSTREAM AT 250 HPA
FOUND ON THE 12Z UPA ANALYSIS IS LIKELY STARTING TO PUSH INTO THE
REGION AND THIS IS CONFIRMED LOOKING AT THE TUCUMCARI WIND PROFILE
AS SPEEDS ALOFT ARE STARTING TO INCREASE.  COMBINATION OF THE
SURFACE DRYLINE/TROF AND STRONGER UPPER LEVEL SUPPORT SHOULD RESULT
IN AT LEAST SCATTERED SHOWERS AND STORMS...ESPECIALLY ACROSS THE
ROLLING PLAINS.  NAM CONTINUES TO HIGHLIGHT AREAS AROUND CHILDRESS
WHILE THE GFS TRIES TO DEVELOP PRECIPITATION FURTHER SOUTH INTO THE
CENTRAL SOUTH PLAINS.  THE HRRR AND OPERATIONAL RUC BOTH HAVE
CONSISTENTLY FAVORED THE NORTHEASTERN ROLLING PLAINS /AREAS AROUND
CHILDRESS/ FOR CONVECTIVE DEVELOPMENT THIS AFTERNOON.  HOWEVER...
LAST THREE RUNS OF THE HRRR HAVE ALSO STARTED TO DEVELOP ISOLATED
STORMS CLOSER TO LUBBOCK BY 23Z THIS AFTERNOON.  ISOLATED SEVERE
WEATHER REMAINS IN PLAY AS SPEED SHEAR INCREASES WITH THE JET MOVING
OVER THE AREA BUT DIRECTIONAL SHEAR REMAINS RATHER MEAGER.  BULK
SHEAR VALUES ARE HIGH ENOUGH THAT SOME STORM ORGANIZATION COULD TAKE
PLACE AND THE HRRR HAS BEEN HINTING AT THIS IN THE COMPOSITE
REFLECTIVITY FIELDS.  BEST CHANCES FOR SEVERE WEATHER WILL REMAIN
OVER THE NORTHERN ROLLING PLAINS WHERE SHEAR VALUES LOOK TO BE THE
HIGHEST.

WITH ALL THIS IN MIND...WILL KEEP SLIGHT CHANCE/ISOLATED POPS ACROSS
THE CENTRAL ZONES BUT WILL BUMP UP POPS TO 50 PERCENT ACROSS THE
NORTHERN ROLLING PLAINS WHERE CONVECTIVE SIGNAL HAS BEEN STRONGER IN
THE MODELS.  EXPECT TO SEE ANY STORMS THAT DO DEVELOP DISSIPATE
SHORTLY AFTER MIDNIGHT WITH ZERO POP CHANCES AFTER THAT INTO THE DAY
WEDNESDAY.  A WEAK COLD FRONT PUSHING INTO THE AREA TOMORROW MORNING
WILL ALSO HELP TO LOWER RAIN CHANCES AS SLIGHTLY DRIER AIR WORKS IN
FROM THE NORTH AND ANY MID/UPPER LEVEL SUPPORT PUSHES WELL EAST OF
THE AREA.  TEMPERATURES SHOULD BE CLOSE TO OR A TAD BIT WARMER THAN
WHAT WE HAVE SEEN SO FAR TODAY MAINLY DUE TO THE LACK OF LOW CLOUDS
EXPECTED TOMORROW MORNING.

.LONG TERM...
UPPER LEVEL TROUGH MENTIONED IN THE SHORT TERM DISCUSSION ABOVE WILL
BE EAST OF THE SOUTHERN PLAINS BY THURSDAY...AS UA RIDGING
COMMENCE TO AMPLIFY ACROSS THE WESTERN CONUS THUS INDUCING NW
FLOW ALOFT. SFC WINDS WILL RETURN TO THE SOUTH BY LATE THURSDAY
AFTERNOON/EVENING THANKS TO A SFC HIGH SE OF THE REGION. MODEL
SOUNDINGS DISPLAYED DRYING ATMOSPHERIC LEVELS /PWATS AOA 0.60
INCHES/...HENCE PRECIP CHANCES ARE SLIM DESPITE NW FLOW ALOFT.
THEREAFTER...SFC LEE TROUGHING NORTH OF THE REGION MAY INDUCE
SLIGHTLY BREEZY SOUTHERLY WINDS DURING THE AFTERNOON HOURS
THROUGHOUT THE WEEKEND...WHILE CONCURRENTLY THE UA RIDGE SLOWLY
TRANSLATES EAST ACROSS THE SOUTHERN PLAINS. THOUGHTS OF HURRICANE
JOVA AND ITS ASSOCIATED MOISTURE NEARING THE SOUTH PLAINS DO NOT
LOOK VERY OPTIMISTIC...AS ITS PROJECTED NORTHWARD TRAJECTORY
ACROSS THE MOUNTAINOUS TERRAIN OF SOUTHWESTERN OLD MEXICO WILL AID
TO DIMINISH IT TO TROPICAL DEPRESSION STRENGTH BY FRIDAY. ANY
HINTS OF SFC MOISTURE ADVECTION APPEARS TO QUICKLY SCOUR OUT AS
SUBSIDENCE TAKES OVER.

BOTH THE GFS AND ECMWF APPEARS TO BE IN BETTER AGREEMENT IN REGARD
TO SHOWING THE UA RIDGE SLOWLY PROPAGATING EAST ACROSS THE SOUTH
PLAINS THIS WEEKEND...WHERE THEREAFTER DE-AMPLIFICATION OCCURS NEXT
WEEK THANKS TO A  NORTHWESTERLY DISTURBANCE MOVING ACROSS THE
NORTHERN PLAINS. THIS SAID DISTURBANCE HAS AN ASSOCIATED FROPA THAT
IS PROGGED TO MOVE SOUTH ACROSS THE CWA TUESDAY. LATEST GFS HAS
BACKED OFF SIGNIFICANTLY IN REGARD TO PRECIP DEVELOPMENT ALONG THE
FRONT...WHILE THE CURRENT RUN OF THE ECMWF DEVELOPS PRECIP MAINLY
ACROSS THE NORTHERN LOCALES. THUS WILL MAINTAIN SILENT POPS AS THE
ANALYZING OF FUTURE MODEL RUNS FOR CONSISTENCY IS HIGHLY DESIRED.
WILL ALSO SHOW TEMPS SLIGHTLY ABOVE AVG THROUGHOUT THE WEEKEND...WITH
A DIP BELOW SEASONAL NORMS BY NEXT WEEK...ESPECIALLY IF THE
TEMPORAL DISTRIBUTION OF THE ANTICIPATED FRONT REMAINS IN TACT.
