AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
258 PM CDT WED MAY 23 2012

.DISCUSSION...
THE UPPER LEVEL RIDGE OVER NORTHEAST MEXICO WILL BUILD ACROSS
SOUTH CENTRAL TEXAS ON THURSDAY AND PERSIST INTO FRIDAY. THE
UPPER LEVEL HIGH WILL THEN MIGRATE EASTWARD BECOMING CENTERED
OVER THE MISSISSIPPI VALLEY BY SUNDAY. THE UPPER LEVEL RIDGE
WILL THEN BUILD BACK TO THE WEST EARLY NEXT WEEK ACROSS SOUTH
CENTRAL TEXAS. THIS UPPER LEVEL PATTERN WILL KEEP SOUTH CENTRAL
TEXAS WARM AND DRY. THE EXCEPTION WILL BE SATURDAY THRU MONDAY
WHEN ISOLATED AFTERNOON CONVECTION IS POSSIBLE ACROSS OUR
SOUTHERN TIER OF COUNTIES. THE WEAKENING OF THE RIDGE ALOFT
COMBINED WITH AFTERNOON HEATING AND LOW LEVEL CONVERGENCE
ALONG THE SEA-BREEZE BOUNDARY MAY BE ENOUGH TO TRIGGER ISOLATED
CONVECTION.

THE LOW-LEVEL FLOW WILL BE OFF THE GULF SO THE PATTERN OF LATE
NIGHT AND MORNING LOW CLOUDS CAN BE EXPECTED BEGINNING TONIGHT.
LOW CLOUDS MAY BE SLOW TO MIX OUT OVER THE BALCONES ESCARPMENT
THURSDAY AND FRIDAY DUE TO A STRONG CAPPING INVERSION ALOFT.
AFTERNOON HIGHS AND MORNING LOWS WILL RUN SLIGHTLY ABOVE NORMAL
THRU THIS FORECAST CYCLE.

ACROSS PORTIONS OF THE EDWARDS PLATEAU. MINIMUM RELATIVE HUMIDITIES
