AREA FOR CONVECTIVE DEVELOPMENT DUE TO WEAK LOW LEVEL CONVERGENCE.
PWS AROUND 2 INCHES...A WEAK VORT MAX WEST OF BIG BEND MOVING
EASTWARD AND DIFFERENTIAL HEATING ALONG THE SFC BOUNDARY WILL
ALSO AID IN THE DEVELOPMENT OF CONVECTION THIS AFTERNOON. HAVE

WIDESPREAD BKN-OVC MVFR CIGS/MVFR VSBYS IN BR THIS MORNING AS
VERY WARM MOIST GULF AIR HAS PUSHED INTO S TX. AN INCREASING SLY
PRESSURE GRADIENT AND HIGH DEW POINTS THIS MORNING BEHIND THE WARM
FRONT...CAUSED THE QUICK FORMATION OF THE STRATUS OVERNIGHT...WHICH
DID NOT ALLOW FOR ANY DENSE FOG FORMATION. A FEW LIGHT STREAMER
SHRA ARE POSSIBLE OFF THE GULF MAINLY EAST OF I35 THIS MORNING.
OTHERWISE THE STRATUS DECK WILL SLOWLY LIFT AND BREAK OR SCATTER
OUT TO VFR MOST AREAS BY 17Z. SCT CU AT 35-45 HND FEET THIS
AFTERNOON. AN APPROACHING COLD FRONT FROM NORTH TX WILL MOVE TO
THE NRN HILL COUNTRY BY MID TO LATE AFTERNOON WITH SCT SHRA/TSRA
DEVELOPING ALONG AND AHEAD OF THE COLD FRONT. THE COLD FRONT WILL
MOVE TO NEAR A KDRT-25N KSAT-25E KAUS LINE BY 03Z. SCT-NMRS
SHRA/TSRA CAN BE EXPECTED WITH THE COLD FRONT...SOME SEVERE WITH
LARGE HAIL AND DAMAGING DOWN-BURST WINDS. SELY SFC WINDS OF 10 TO

.PREV DISCUSSION... /ISSUED 421 AM CDT TUE OCT 6 2009/

DISCUSSION...
WARM AND HUMID CONDITIONS ARE IN STORE TODAY AS MOIST SOUTHEAST
SFC FLOW CONTINUES AHEAD OF A COLD FRONT. SHOWERS AND
THUNDERSTORMS WILL DEVELOP ALONG THE FRONTAL BOUNDARY AND ARE
EXPECTED TO REACH THE HILL COUNTRY BY MID AFTERNOON. THE FRONT
WILL GRADUALLY DRIFT SOUTHWARD AND STALL ACROSS THE MIDDLE OF THE
CWA OVERNIGHT. RAIN CHANCES WILL INCREASE AHEAD OF AND ALONG THE
FRONT LATE IN THE AFTERNOON AND THROUGH THIS EVENING. SPC HAS
CONTINUED A SLIGHT RISK FOR SEVERE STORMS ACROSS THE NORTH AND
NORTHEASTERN PORTION OF OUR CWA WITH THIS SYSTEM. THE GREATEST
THREAT WILL GENERALLY BE ALONG AND NORTHEAST OF A LINE FROM
ROCKSPRINGS TO SAN ANTONIO TO LA GRANGE WITH CONCERNS OF LARGE
HAIL AND DAMAGING WINDS THIS AFTERNOON AND INTO THE OVERNIGHT
HOURS.

THE WEAKENED BOUNDARY WILL LINGER ACROSS THE REGION ON WEDNESDAY
INVITING A CONTINUED CHANCE FOR RAIN. THE FRONT WILL SHIFT OUT OF
THE REGION WEDNESDAY AFTERNOON WITH WARM AND HUMID CONDITIONS
RETURNING THURSDAY. HOWEVER...AN APPROACHING COLD FRONT SET TO
ARRIVE ON FRIDAY WILL REMEDY THE UNCOMFORTABLE CONDITIONS. RAIN
CHANCES WILL BEGIN TO INCREASE THURSDAY NIGHT AND WILL PEAK ON
FRIDAY AS THE FROPA PUSHES ACROSS THE REGION. COULD SEE ANOTHER
ROUND OF STRONG STORMS WITH HEAVY RAIN WITH THIS SYSTEM. RAIN
CHANCES WILL END FROM NORTHWEST TO SOUTHEAST LATE FRIDAY AS THE
FRONT REACHES THE COAST.

DRY AND MILD CONDITIONS ARE IN STORE FOR THE WEEKEND AND EARLY
NEXT WEEK. BOTH MAX AND MIN TEMPERATURES WILL GENERALLY BE A FEW
DEGREES COOLER THAN MID-OCTOBER NORMALS.

.AVIATION...
CURRENTLY THE SHOWERS THAT WERE MOVING NORTHEAST THROUGH SOUTH CENTRAL
TEXAS HAVE CLEARED THE AREA. AFTER BRIEF CLEARING... CU HAS
REFORMED AND ADDITIONAL SHOWERS ARE FORMING PARTICULARLY AROUND
AUSTIN. FOR THIS AFTERNOON AND INTO THE EVENING... ISOLATED TO
SCATTERED SHOWERS AND THUNDERSTORMS ARE POSSIBLE ESPECIALLY ALONG AND
EAST OF I-35. WINDS SHOULD STAY SOUTHEAST AROUND 12 KTS. CIGS
SHOULD STAY VFR... HOWEVER IF A SHOWER OR THUNDERSTORM COMES
THROUGH CIGS COULD DROP TO MVFR CONDITIONS. THE FRONT SHOULD MOVE
THROUGH KDRT AROUND 06Z AND ALONG THE I-35 CORRIDOR AROUND 12Z.
PRECIP SHOULD END PRIMARILY WITH THE FRONTAL PASSAGE WITH CIGS
SLOWLY RISING.

.PREV DISCUSSION... /ISSUED 1102 AM CDT WED OCT 21 2009/

UPDATE...
WARM/MOIST ADVECTION SHOWERS CONTINUED ACROSS EASTERN AREAS OF
SOUTH CENTRAL TEXAS. PWS HAVE INCREASED INTO THE 1.6 TO 1.8 INCH
RANGE THIS MORNING. TROPICAL STORM RICK HAS MADE LANDFALL NEAR
MAZATLAN. EXTRAPOLATION OF UPPER LEVEL VORTICITY ASSOCIATED WITH
MOVES ACROSS SOUTHERN AND CENTRAL TEXAS TONIGHT. MODELS SHOW
HEAVIEST RAINS OVERNIGHT. COLD FRONT MOVES ACROSS AREA THURSDAY
MORNING INTO EARLY AFTERNOON. PASSAGE OF THIS FEATURE WILL END
RAIN CHANCES. SOUTH CENTRAL TEXAS FORECAST IS ON TRACK WITH ONLY
MINOR ADJUSTMENTS TO THE SENSIBLE WEATHER GRIDS FOR THIS AFTERNOON
INTO THIS EVENING.

PREV DISCUSSION... /ISSUED 646 AM CDT WED OCT 21 2009/

DISCUSSION...
SEE AVIATION SECTION.

AVIATION...
MVFR TO VFR CEILINGS WILL HOLD WITH OCCASIONAL MVFR VSBY IN
SHOWERS OR THUNDERSTORMS. A COLD FRONT WILL MOVE FROM WEST TO
EAST, REACHING KDRT ARND 04Z AND KAUS/KSAT/KSSF ARND 12Z. ALONG
THE LEADING EDGE OF THE COLD FRONT WILL BE SCATTERED
THUNDERSTORMS. MOIST SOUTHEAST WINDS AT 10 TO 15 KTS WILL
PREVAIL. AS THE COLD FRONT PASSES THE TERMINALS, WINDS WILL SHIFT
TO THE NORTHWEST AT 15 GUSTING TO 25 KTS.

PREV DISCUSSION... /ISSUED 331 AM CDT WED OCT 21 2009/

DISCUSSION...
GULF MOISTURE WILL STREAM NORTH TODAY IN ADVANCE OF A PROGRESSIVE
UPPER LOW MOVING EAST INTO THE TEXAS PANHANDLE. TROPICAL PLUME FROM
TROPICAL STORM RICK WILL ADD INGREDIENT FOR HEAVIER RAINS. RICK
IS EXPECTED TO HIT MAINLAND MEXICO LATER TODAY. THE COMBINED
LOW LEVEL GULF AND MID/UPPER PACIFIC MOISTURE FROM RICK WILL
RESULT IN A DEEP MOIST AND MORE BUOYANT ATMOSPHERE. WEAK DISTURBANCES
ALOFT AND SURFACE CONVERGENCE WILL PRODUCE SCATTERED TO NUMEROUS
SHOWERS AND THUNDERSTORMS MAINLY OVER THE EASTERN HALF OF THE
CWA TODAY. PW (PRECIPITABLE WATER) VALUES WILL BE ON AVERAGE AN
INCH AND A HALF OR GREATER THROUGHOUT MUCH OF THE CWA TODAY SO
SOME MODERATE SHOWERS OR STORMS ARE NOT OUT OF THE QUESTION. AS
THE SYSTEM MOVES OUT OVER THE SOUTHERN U.S. PLAINS TONIGHT..THE
TROPICAL PLUME WILL TEND TO TRANSLATE SOUTHEAST OF THE CWA AS
DRIER WESTERLY WINDS SWEEP INTO THE AREA. THIS WILL LOWER PW`S
THROUGHOUT THE AREA AT THE SAME TIME THE FRONT PUSHES THROUGH
TOMORROW. THUS.. RICK`S IMPACT TO OUR REGION (IN TERMS OF HEAVIER
RAINFALL) MAY BE SOMEWHAT LIMITED WHEN THE FRONT PUSHES THROUGH.
THE FRONT WILL PUSH THROUGH RAPIDLY DURING THE DAY THURSDAY WITH
SHOWERS AND THUNDERSTORMS EXPECTED TO LINE THE FRONT. A FLASH
FLOOD WATCH WILL NOT BE ISSUED AT THIS TIME. SURFACE RIDGE WILL
BUILD IN THURSDAY NIGHT WITH MOSTLY SUNNY AND MILD WEATHER FOR
FRIDAY. THE GFS DEVELOPS AN UPPER LOW OVER BAJA IN 72 HOURS
(FRIDAY NIGHT) AND WILL MONITOR IN LATER RUNS FOR CONSISTENCY.
NONETHELESS..WILL KEEP DRY WESTERLIES ALOFT ACROSS REGION SATURDAY.
A SURFACE LOW WILL DEEPEN OVER THE TEXAS SOUTH PLAINS SATURDAY
(WITH ZONAL FLOW ALOFT) THUS..SOUTHERLY FLOW RETURNS TO OUR AREA
WITH WARMER NIGHTTIME LOWS FORECAST. AM DISCOUNTING UPPER LOW
FORMING FOR NOW ACROSS BAJA THUS THE WEAK DISTURBANCE ALOFT WILL
BE DISCOUNTED AS WELL ON SUNDAY. WILL SEE IF THIS FEATURE IS
CONTINUED ON SUBSEQUENT MODEL RUNS SO STAY TUNED. WESTERLIES ALOFT
(WITH SOUTH WINDS AT THE SURFACE) WILL DOMINATE THE FIRST HALF OF
THE WORK WEEK WITH WARM DAYS AND MILD NIGHTS MONDAY THROUGH
WEDNESDAY.
