AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
355 PM CDT MON MAY 11 2009

.DISCUSSION...
THE FORECAST IS TRENDING WETTER FROM THE PREVIOUS COUPLE OF
FORECAST CYCLES. A WEAKNESS IN THE UPPER RIDGE...COUPLED WITH
GREATER SURFACE-BASED INSTABILITIES TODAY (VS. YESTERDAY) IS
ALLOWING FOR ISOLATED CONVECTION OVER OUR COASTAL PLAINS. THIS
AREA OF SHOWERS AND THUNDERSTORMS IS CREEPING NORTHWARD OVER
SURFACE DEWPOINT TEMPERATURES IN THE 70S. AT THE SAME TIME...A
COLD FRONT IS CURRENTLY ORIENTED ALONG A LINE FROM TAYLOR...TO
AUSTIN...TO NEAR MASON AND MOVING SOUTH. THIS FRONT IS A RAIN-
COOLED AND OUTFLOW-ENHANCED AIRMASS FROM CONVECTION ACROSS NORTH
TEXAS EARLIER TODAY AND LAST NIGHT. THE SOUTHWARD PROGRESS OF THIS
BOUNDARY WILL SLOW DOWN OVER THE NEXT COUPLE OF HOURS...BUT MAY
HOOK UP AND ENHANCE THE CURRENT ROUND OF THUNDERSTORMS BETWEEN NEW
BRAUNFELS AND SAN MARCOS BEFORE INSTABILITIES ARE SPENT AND
DIURNAL CONVECTIVE TRENDS (DOWN) TAKE-OVER. THE 18Z RUC AND NAM12
DATA SHOW THE EXPANSION OF PRECIP OVER THE SOUTHERN HILL COUNTRY
AND SAN ANTONIO METRO AREA OVER THE NEXT FEW HOURS...BUT THE
WESTWARD DEVELOPMENT OF THIS ROUND SEEMS TO HAVE STOPPED.

A SHORTWAVE RIDGE IS FORECAST TO MOVE OVER OUR AREA TOMORROW AND
WILL KEEP A LID ON CONVECTION. THE WESTERLIES WILL PUSH BACK INTO
OUR AREA ON WEDNESDAY AND A SERIES OF WEAK SHORTWAVE TROUGHS ARE
FORECAST TO MOVE ACROSS TEXAS THROUGH SATURDAY...INTERACTING WITH
A JUICY GULF ATMOSPHERE AND PRODUCING SCATTERED SHOWERS AND
THUNDERSTORMS. A COLD FRONT IS FORECAST TO PUSH THROUGH SUNDAY AND
WILL BRING AN END TO OUR RAIN CHANCES AS IT PUSHES TO THE COAST
SUNDAY NIGHT AND THEN OFFSHORE. TEMPERATURES BEHIND THE FRONT NEXT
SUNDAY NIGHT AND MONDAY WILL BE CLOSE TO NORMAL.
