AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE AUSTIN/SAN ANTONIO TX
326 PM CDT TUE SEP 2 2014

.SHORT TERM (TONIGHT THROUGH WEDNESDAY NIGHT)...
TROPICAL STORM DOLLY WILL MAKE LANDFALL IN NORTHEASTERN MEXICO
THIS EVENING. A SOUTHEASTERLY FLOW HAS ALLOWED A DEEPER MOIST
AIRMASS WITH PWS NEAR 2 INCHES TO MOVE INLAND ACROSS THE COASTAL
PLAINS. WIDELY SCATTERED AND AN OCCASIONAL THUNDERSTORM HAVE
DEVELOPED ALONG AND EAST OF I-35. THESE WILL CONTINUE TO MOVE TO
THE NORTHWEST BEFORE DISSIPATING THIS EVENING BY A LITTLE AFTER
SUNSET. AS DOLLY MOVES FURTHER INLAND AND WEAKENS...THIS DEEPER
MOISTURE SPREADS FURTHER WEST ACROSS SOUTH CENTRAL TEXAS. EXPECT
SHOWERS AND THUNDERSTORMS TO DEVELOP EARLY IN THE MORNING NEAR THE
COASTAL PLAINS AND THEN SPREAD WEST ACROSS THE AREA DURING THE DAY
WITH DISSIPATION MOST AREAS BY SUNSET. COVERAGE WILL BE SCATTERED
IN THE SOUTH AND BECOME MUCH MORE ISOLATED IN THE NORTH CLOSER TO
SUBTROPICAL RIDGE. LOCALLY HEAVY RAINFALL IS POSSIBLE DUE TO PWS
NEAR 2 INCHES. HAVE MAINTAINED LOW CHANCE POPS WEDNESDAY NIGHT
MAINLY ACROSS THE RIO GRANDE PLAINS DUE TO UPSLOPE FLOW ENHANCING
LIFT AND CLOSER PROXIMITY TO THE NIGHTTIME RAINS ASSOCIATED WITH
THE CENTER OF THE REMNANT LOW OF TROPICAL STORM DOLLY. A SLIGHT
COOLING OF HIGHS IS EXPECTED ACROSS SOUTHERN PARTS OF OUR AREA ON
WEDNESDAY DUE TO MORE CLOUDS AND RAIN.

&&

.LONG TERM (THURSDAY THROUGH TUESDAY)...
THURSDAY INTO FRIDAY...THE REMNANT LOW OF DOLLY WILL DISSIPATE.
HOWEVER...MOISTURE LEVELS ARE SLOW TO DECREASE AS THE SUBTROPICAL
RIDGE BECOMES MORE DOMINANT. ISOLATED TO SCATTERED ARE EXPECTED
DURING THE DAYTIME HOURS...RETREATING TO THE RIO GRANDE PLAINS
THURSDAY NIGHT AND FRIDAY NIGHT. SATURDAY THROUGH MONDAY...THE
SUBTROPICAL RIDGE SETTLES OVER OUR AREA. ISOLATED SHOWERS AND
THUNDERSTORMS ARE POSSIBLE ALONG THE SEABREEZE NEAR THE COASTAL
PLAINS. IN ADDITION...ON SUNDAY...A WEAK SURFACE BOUNDARY BRIEFLY
MOVES INTO CENTRAL TEXAS. ISOLATED SHOWERS AND THUNDERSTORMS ARE
POSSIBLE ACROSS OUR NORTHERN COUNTIES. BY TUESDAY...THE BOUNDARY
DISSIPATES AND THE RIDGE BECOMES MORE DOMINANT ENDING THE RAIN
CHANCES. HIGH TEMPERATURES WARM SLIGHTLY UNDER THE RIDGE...EXCEPT
A BRIEF DIP ACROSS THE FAR NORTHEAST ON SUNDAY DUE TO CLOUDS AND
RAIN. LOW TEMPERATURES WILL BE NEAR TO SLIGHTLY ABOVE SEASONABLE
LEVELS.
