AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
253 PM CDT THU AUG 13 2015

.SHORT TERM (TONIGHT THROUGH FRIDAY NIGHT)...
ISOLATED CONVECTION HAS DEVELOPED ACROSS AREAS MAINLY SOUTHWEST OF
A LINE FROM FREDERICKSBURG TO NEW BRAUNFELS TO HALLETSSVILLE. LIKE
WE SAW LAST NIGHT...SOME OF THE CONVECTION COULD PRODUCE STRONG
WIND GUSTS INTO THE EVENING HOURS AFTER WHICH WE SHOULD SEE THE
SHOWERS AND STORMS COME TO AN END. HAVE ENDED THE HEAT ADVISORY
FOR THE COASTAL COUNTIES AS AN INCREASE IN CLOUD COVER AND STORM
OUTFLOWS SHOULD KEEP THE TEMPS AND HEAT INDEX VALUES JUST BELOW
CRITERIA. CANT RULE OUT A FEW LOCATIONS HITTING CRITERIA FOR THE
NEXT FEW HOURS BUT THEY SHOULD BE FAIRLY ISOLATED.

SHOULD SEE A REPEAT TOMORROW WITH A BIT LESS COVERAGE OF
POP...WITH THE AREA BEING PUSHED FARTHER TO THE WEST AS DRY AIR
ALOFT TRIES TO COME IN FROM THE NE. MESO MODELS CONTINUE TO SHOW
SOME CONVECTION COMING DOWN FROM THE WEST CENTRAL TEXAS. SEEMS
LIKE A PLAUSIBLE SOLUTION BASED OFF WATER VAPOR AND THE POSITION
OF THE UPPER RIDGE TO THE WEST. NOT MUCH CHANGE IN DAYTIME TEMPS.

&&

.LONG TERM (SATURDAY THROUGH THURSDAY)...
SOME CHANGES START TAKING SHAPE OVER THE WEEKEND INTO EARLY NEXT
WEEK WHEN THE MODELS ARE SHOWING AN UPPER LOW MOVING INTO THE
CENTRAL AND WEST GULF...AND THEN INTO SOUTH TEXAS. THIS SHOULD
INCREASE THE POP CHANCES ESPECIALLY ALONG THE COAST ZONES AND
BRING IN LOWER HEIGHTS...MORE CLOUDS...AND SUBSEQUENT LOWER TEMPS.
HOPEFUL THAT TEMPS WILL DROP BELOW 100 IN MOST AREAS BY THE EARLY
PART OF NEXT WEEK WHEN POP IS THE HIGHEST. STAYED BELOW THE
LARGEST POP ADVERTISED BY THE GFS FOR NOW...BUT IF THE SYSTEM
DEVELOPS...AND DOES BRING A GOOD FETCH OF GULF MOISTURE WITH
IT...COULD SEE THE NEED TO INCREASE POPS...STAY TUNED. TOWARD THE
MIDDLE AND LATER PART OF NEXT WEEK...THE UPPER LOW GOES AWAY AND
WE RETURN TO A DRIER PATTERN ONCE AGAIN.
