...SHOWERS AND THUNDERSTORMS EXPECTED THANKSGIVING EVENING...

A VIGOROUS UPPER LEVEL DISTURBANCE LOCATED OVER WEST TEXAS WILL
CONTINUE ADVANCING EAST TOWARD THE COASTAL BEND TONIGHT. WARM MOIST
AIR AHEAD OF THIS SYSTEM WILL CONTRIBUTE TO THE DEVELOPMENT OF
SHOWERS AND A FEW THUNDERSTORMS THIS EVENING. SCATTERED SHOWERS AND
THUNDERSTORMS CAN BE EXPECTED INTO THE EARLY MORNING HOURS ON FRIDAY.
STRONG THUNDERSTORMS ARE LIKELY TO DEVELOP NORTH OF A LINE FROM TO
ALICE TO ARANSAS PASS AND EAST OF INTERSTATE 37.

THERE IS A SLIGHT RISK FOR SEVERE THUNDERSTORMS LATE TONIGHT MAINLY
NEAR AND TO THE NORTH OF THE VICTORIA AND CROSSROADS AREA. THE
GREATEST THREAT FROM THESE THUNDERSTORMS WILL BE LARGE HAIL AND
DAMAGING WINDS.

A COLD FRONT WILL MOVE WELL OFFSHORE BY LATE FRIDAY MORNING. BEHIND
THE FRONT...STRONG NORTH WINDS ARE EXPECTED TO DEVELOP. BY FRIDAY
EVENING...THE WINDS WILL BEGIN TO DIMINISH. FAIR...BUT COOL
CONDITIONS ARE THEN EXPECTED FOR THE REMAINDER OF THANKSGIVING
WEEKEND.

MOTORISTS TRAVELING ACROSS THE REGION...ESPECIALLY THIS EVENING AND
TONIGHT...SHOULD TAKE EXTRA PRECAUTIONS AND ALLOW EXTRA DRIVING
TIME TO REACH DESTINATIONS. SHOWERS AND THUNDERSTORMS WILL PRODUCE
BRIEF HEAVY RAINFALL...REDUCE VISIBILITIES AND CAUSING PONDING OF
WATER OVER FLATTER TERRAIN...IN ADDITION TO MAKING ROADWAYS SLICK AND
DANGEROUS.

RESIDENTS AND MARINERS ALIKE...SHOULD CONTINUE TO MONITOR THE LATEST
FORECASTS FROM THE NATIONAL WEATHER SERVICE...LOCAL TELEVISION OR
RADIO AND PREPARE ACCORDINGLY FOR THESE CHANGING WEATHER CONDITIONS.
