AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
309 AM CDT TUE SEP 23 2014

.SHORT TERM (TODAY THROUGH WEDNESDAY)...
MOIST AIR CONVERGENCE IN THE 925-850MB LAYER HAS RESULTED IN
ISOLATED SHOWERS ALONG THE COASTAL PLAINS. DRIER AIR FILTERING IN
FROM THE NORTH SHOULD KEEP THESE SHOWERS ISOLATED AND SOUTH OF
U.S. 90 THROUGH THE MORNING. THE POOLED MOIST AIR WILL BE ALONG
THE RIO GRANDE PLAINS THIS AFTERNOON AS AFTERNOON PEAK HEATING IS
REACHED...RESULTING IN SCATTERED SHOWERS AND THUNDERSTORMS FOR
THAT AREA. HOWEVER...WE EXPECT THESE TO BE RELATIVELY LIGHT AND
SHORT-LIVED...AS THEY SHOULD QUICKLY MOVE WESTWARD INTO MEXICO.
THE REST OF THE AREA WILL BE DRY TODAY...AND ALL OF SOUTH CENTRAL
TEXAS WILL REMAIN DRY THROUGH THURSDAY. TEMPERATURES WILL BE
SLIGHTLY BELOW NORMAL THROUGH WEDNESDAY NIGHT.

&&

.LONG TERM (WEDNESDAY NIGHT THROUGH MONDAY)...
THE MEDIUM RANGE MODELS ARE STILL IN FAIR TO POOR AGREEMENT WITH
THE PLACEMENT AND STRENGTH OF THE CUT-OFF LOW PROJECTED TO BE OVER
TEXAS BY FRIDAY...THEN EVENTUALLY EJECTING OUT INTO THE MID-
MISSISSIPPI VALLEY AS A DEEPER SHORTWAVE TROUGH PROGRESSES ACROSS
THE COUNTRY THIS WEEKEND. DESPITE THE VARIETY OF MODEL SOLUTIONS...ALL
GENERALLY POINT TOWARD MINIMAL POPS AND NEAR NORMAL TEMPERATURES
FRIDAY THROUGH SUNDAY. THE BEST CHANCE FOR RAIN IS FRIDAY ALONG
AND SOUTH OF U.S. 90...BUT ONLY A SLIGHT CHANCE AND MANY AREAS
WILL REMAIN DRY. THERE APPEAR TO BE INCREASING PROSPECTS FOR A
COLD FRONT THE MIDDLE OF NEXT WEEK...BUT STILL A LOT OF
UNCERTAINTY AND BEYOND THE SEVEN-DAY FORECAST TO DISCUSS MORE
THAN THIS BRIEF MENTION.
