SHORT TERM (TONIGHT THROUGH THURSDAY NIGHT)...
UPPER AIR ANALYSIS THIS MORNING SHOWED A TROUGH EXTENDING FROM THE
MIDDLE MISSISSIPPI VALLEY TO THE TEXAS COAST WITH A RIDGE BUILDING
OUT OF MEXICO INTO THE SOUTHERN PLAINS. AT THE SURFACE...HIGH
PRESSURE WAS CENTERED TO THE EAST. THE PRESSURE GRADIENT WAS
FAIRLY LOOSE AND WINDS WERE GENERALLY LIGHT FROM THE EAST TO
SOUTHEAST. THE UPPER LEVEL RIDGE WILL TRY TO RE-ESTABLISH ITSELF
OVER TEXAS DURING THIS PERIOD...BUT WILL INITIALLY BUILD OVER THE
TOP OF THE TROUGH. THIS WILL MEAN A WEAKNESS OVER SOUTH CENTRAL
TEXAS AND SOME CHANCE FOR THUNDERSTORMS THURSDAY. THE BEST CHANCES
WILL BE OVER THE EASTERN HALF OF THE CWA.

LONG TERM (FRIDAY THROUGH WEDNESDAY)...
THE UPPER RIDGE WILL PUSH THE TROUGH OFF TO THE EAST AND ONCE
AGAIN BECOME DOMINANT OVER THE REGION. THIS WILL RETURN MORE
TYPICAL LATE SUMMER WEATHER TO SOUTH CENTRAL TEXAS. THE LOW LEVEL
FLOW WILL BE FROM THE SOUTHEAST. THIS WILL BRING ENOUGH MOIST AIR
FROM THE GULF TO INCLUDE SLIGHT CHANCE POPS OVER THE COASTAL
PLAINS DURING THE AFTERNOON AND EARLY EVENING HOURS EACH DAY
THROUGH TUESDAY. TEMPERATURES WILL CONTINUE WITHIN A FEW DEGREES
OF NORMAL.
