Area forecast discussion, Aug 15, 1:53 PM CST, 4 hours 7 minutes before
SOUTH CENTRAL TEXAS FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
253 PM CDT THU AUG 15 2002

A WARBLE IN THE MOVEMENT OF A SMALL MID-LEVEL LOW OVER SOUTHEAST TX
AND RAIN COOLED OUTFLOW FROM NUMEROUS THUNDERSTORMS HAS RESULTED IN
AN INCREASE IN THUNDERSTORMS OVER EASTERN SECTIONS OF SOUTH CENTRAL
TX THIS AFTERNOON. SOME LOCALLY HEAVY RAINFALL CAN BE EXPECTED OVER
FAYETTE AND LAVACA COUNTIES THROUGH THIS EVENING, BUT THE CHANCE OF
RAIN WILL BE ONLY IN THE 10-30 PERCENT RANGE WESTWARD TO THE AUSTIN
AND SAN ANTONIO AREAS.

UPPER SHEAR AXIS ABOVE THE MID-LEVEL LOW SHOULD GRADUALLY WEAKEN SO
CONVECTION WILL RETURN TO A SEABREEZE VARIETY OVER THE WEEKEND. THE
NEXT WEATHER FEATURE TO WATCH IS AN UPPER LOW FORECAST TO MOVE INTO
SOUTH CENTRAL TEXAS ON MONDAY BY THE AVN/MRF. IF THIS FEATURE HOLDS
THERE COULD BE A CHANCE FOR MORE HEAVY RAINS. THE ETA MODEL HAS THE
SAME FEATURE AT 60 HOURS IN THE FORM OF A SHEAR AXIS OVER NW/WRN TX
MATCHING UP WITH THE AVN/MRF NICELY. FOR NOW, WILL CONTINUE TO KEEP
THE FORECAST POPS OVER SOUTHEAST COUNTIES AND SOME ISOLATED POPS AT
AUS/SAT THROUGH THE EXTENDED. THE LATEST MRF HAS THE STRONGEST PART
OF THE UPPER RIDGE SHIFTING EAST INTO THE SERN US BY TUESDAY OTHER
MEDIUM RANGE MODELS AGREE. THUS EXPECT ENOUGH WEAKNESS IN THE UPPER
RIDGE TO ALLOW FOR FARTHER PENETRATION OF SEABREEZE CONVECTION NEXT
WEEK. WILL ALSO KEEP HIGH TEMPS IN THE MID 90S FOR THESE AREAS WITH
THE ASSUMPTION THAT THERE WILL BE MORE MOISTURE. EXPECT HOT AND DRY
WEATHER TO CONTINUE THROUGH THE NEXT 7 DAYS FOR WESTERN SECTIONS OF
SOUTH CENTRAL TEXAS.
