AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
306 AM CDT FRI MAY 16 2008

.DISCUSSION...MODELS KEEP CLOSED UPPER LOW OVER NORTHERN MEXICO 
TODAY AND TONIGHT. THE LOW WILL SPIN EJECTING DISTURBANCES EAST
INTO THE WESTERN CWA WHILE CONVECTION WHICH FORMS OVER THE SIERRA
MADRES WILL TEND NORTHEAST IN THE UPPER FLOW TOWARDS THE MIDDLE
RIO GRANDE PLAINS AND SOUTHERN PORTIONS OF SOUTH CENTRAL TEXAS.
THUS PROBABILITIES WILL BE GREATEST TODAY ACROSS THESE AREAS AND
LESS OVER NORTH CENTRAL AND EASTERN AREAS OF THE CWA. UPPER LOW
FILLS (WEAKENS) SATURDAY WITH RAINS ENDING. A POLAR JET DIVES
SOUTH INTO TEXAS SUNDAY EFFECTIVELY CUTTING OFF SOUTHERN STREAM
MOISTURE AND DISTURBANCES, THUS AN EXTENDED PERIOD OF DRY WEATHER
WILL ENSUE. DYNAMIC SUBSIDENCE ALOFT WILL RESULT IN WARMER
TEMPERATURES SUNDAY WITH HIGHS APPROACHING 90 DEGREES WITH LOW TO
MID 90S POSSIBLE OVER WESTERN PORTIONS. UPPER RIDGING WILL BEGIN
BUILDING FROM THE WEST MONDAY MAKING FOR ANOTHER WARM DAY WITH
READINGS IN THE 90S. A BROAD SURFACE TROUGH WILL DEEPEN ACROSS
NORTHERN TEXAS MONDAY WITH SOUTHERLY FLOW ADVECTING GULF MOISTURE
BACK INTO THE REGION. THIS TREND TOWARD MILD NIGHTS TO WARM HUMID
AFTERNOONS WILL CONTINUE THROUGH WEDNESDAY. ANOTHER DEVELOPING
STORM SYSTEM WILL PUSH THROUGH THE SOUTHERN U.S. PLAINS THURSDAY
BUT AT THE PRESENT TIME DUE TO THE UPPER FLOW'S PROGRESSIVE
NATURE..AND SUBSEQUENT STRONG ZONAL WESTERLIES..WE BELIEVE IT WILL
COME THRU DRY.
