NATIONAL WEATHER SERVICE CORPUS CHRISTI TX
245 PM CDT WED SEP 5 2001

UPPER LOW OVER TX PROGD TO SLOWLY BE DRAWN NWD AND ABSORBED BY NEXT
UPPER LOW OVER PAC NW DIGGING SWD ACROSS THE SW U.S. AS A
RESULT...UPPER LEV DISTS WILL CONT ACROSS S TX.

WV SAT INDICATED DRY SLOT ROTATING ACROSS W FA WITH A 50-60 KNOT JET
DIGGING S ACROSS W TX. MODELS PROG PWATS TO INCREASE OVER W FA
OVERNIGHT. THE COMBINATION OF THE DIGGING JET OUT WEST...SFC MOIST
CONV MOVG INLAND AND THE INCREASING PWATS OUT WEST...SHOULD PRODUCE
AND MAINTAIN CONVECTION OVER RIO GRANDE PLAINS TONIGHT.  SATELLITE
AND LTG DATA INDICATED DEVELOPMENT OVER MEX W OF RIO GRANDE PLAINS.

PWATS ARE PROGD TO DECREASE OVER E FA OVERNIGHT. HOWEVER...WITH
CURRENT RADAR INDICATING TRAINING OVER NE FA...CONVECTION OFFSHORE
AND SE OF BRO MOVG NW...AND WITH VERY LOW FFG VALUES...AM INCLINED
TO KEEP FFA IN EFFECT FOR ALL ZONES TONIGHT. FFA MAY BE CANCELLED
LATER TONIGHT FOR COASTAL COUNTIES IF WARRANTED.

AS UPPER LOW BECOMES LESS OF AN INFLUENCE ON THU AND PWATS
DECREASE...FLOODING POTENTIAL ALSO DIMINISHES. SUFFICIENT MOISTURE
AND WEAKENING UPPER LEVEL LOW...WILL REMAIN IN PLACE TO WARRANT LOW
POPS WITH MAYBE SOME LOCALIZED FLOODING.

WITH LESS CLOUDS/RAIN ON THU AND FRI...MAX TEMPS WILL BE WARMER.
WINDS WILL INCREASE NEXT TWO DAYS AS SFC LOW DEEPENDS ACROSS THE
PLAINS.

ETA...AVN AND UKMET PROG AN UPPER LOW CURRENTLY OVER THE PAC NW TO
DIG S OVER THE SW U.S. AND INTO TX WITH AN ASSOC CF TO MOVE INTO N
TX BY LATE FRI. THE AVN BRINGS THIS FRONT THROUGH THE ENTIRE FA BY
SAT NIGHT/SUN MORN. THIS HIGHLY DEPENDS ON JUST HOW FAR S THE UPPER
LOW ACTUALLY DIGS. WILL NOT ENTIRELY JUMP ON THIS SCENARIO JUST YET
SO AS TO AVOID FLIP FLOPPING IF NEXT RUN IS NOT AS AGRESSIVE. WILL
ONLY GO WITH THE CF APPROACHING THE FA. THIS WILL FALL MORE IN LINE
WITH CURRENT EXTENDED AND MRF POPS IN THE 30-40 PERCENT RANGE
THROUGH WED.

MARINE...WEAKNESS IN THE UPPER RIDGE WILL CONTINUE.  H5 LOW
CURRENTLY OVER N TX IS FCST TO WEAKEN AND SLIDE NE.  THIS WILL ALLOW
SLIGHTLY DRIER AIR TO FILTER ACROSS THE REGION.  THERE WILL STILL BE
ENOUGH MOISTURE PRESENT TO MAINTAIN THE MENTION OF AT LEAST ISOLATED
CONVECTION.  RADAR THIS AFTERNOON HAS SHOWN AN INCREASE IN
CONVECTION OVER THE COASTAL WATERS.  SATELLITE PIX SHOW MOISTURE
CURRENTLY CROSSING THE YUCATAN AND ANOTHER AREA ALONG THE MEXICAN
COAST THAT COULD KEEP CHCS FOR PCPN HIGHER THAN FCST SHOWS.  WINDS
WILL BEGIN TO INCREASE AS PRESSURES LOWER ACROSS W TX.  HIGHEST
SPEEDS WILL BE NOTED OVER THE BAYS DURING THE AFTERNOON AND
EVENINGS..WITH OFFSHORE WATERS EXPERIENCING THE NOCTURNAL EFFECT AND
SEEING WINDS HIGHEST AT NIGHT.  EXTENDED IS THE BIGGEST PROBLEM THIS
AFTERNOON..WITH MODELS WANTING TO PUSH A COLD FRONT OFF THE TEXAS
COAST.  WILL AWAIT THE ARRIVAL OF ADDITIONAL DATA BEFORE CHANGING
THE CURRENT THINKING.  LATER SHIFTS WOULD NEED TO MAKE MAJOR CHANGES
IN THE EXTENDED IF THIS SOUTHWARD TREND CONTINUES.

.CRP...NONE.
