THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTHEAST TEXAS.
.DAY ONE...THIS AFTERNOON AND TONIGHT
AN AREA OF LOW PRESSURE OVER THE NORTHWEST GULF OF MEXICO WILL
CONTINUE TO MOVE EAST NORTHEAST THROUGH THIS EVENING. STRONG EAST
TO NORTHEAST WINDS WILL BRING ELEVATED TIDE LEVELS TO THE COAST
THROUGH THIS EVENING. A COASTAL FLOOD ADVISORY HAS BEEN ISSUED
FOR LOW LYING AREAS ALONG THE IMMEDIATE COAST FOR THE THREAT OF
MINOR COASTAL FLOODING..
THIS SYSTEM WILL ALSO PRODUCE WIDESPREAD RAINFALL OVER MUCH OF
SOUTHEAST TEXAS THROUGH TONIGHT. MOST AREAS WILL GENERALLY
RECEIVE BETWEEN A HALF AND ONE INCH OF RAIN WITH AREAS NEAR THE
COAST RECEIVING BETWEEN 2 AND 3 INCHES OF RAIN.
.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY
A STRONG UPPER LEVEL DISTURBANCE COUPLED WITH UNSEASONABLY COLD
AIR WILL TRIGGER AN EPISODE OF WINTER WEATHER ON FRIDAY. AT THIS
TIME...IT APPEARS THAT A COLD RAIN WILL DEVELOP EARLY FRIDAY. THE
PRECIPITATION WILL TRANSITION TO A MIXTURE OF RAIN AND SNOW AND
THEN ALL SNOW BY AFTERNOON AS COLDER AIR CONTINUES TO FILTER INTO
THE REGION. THERE IS SOME POTENTIAL FOR SNOW ACCUMULATIONS ON
FRIDAY. THIS FORECAST IS UNCERTAIN DUE TO CHANGES OF WHEN THE
DISTURBANCE MOVES OVER SOUTHEAST TEXAS AND HOW MUCH MOISTURE WILL
BE AVAILABLE FOR WINTRY PRECIPITATION. MUCH CAN CHANGE BETWEEN
NOW AND FRIDAY SO IT IS IMPORTANT TO KEEP UP WITH THE FORECAST.
PLEASE SEE ANY SPECIAL WEATHER STATEMENTS FOR UPDATED DETAILS.
.SPOTTER INFORMATION STATEMENT...
SPOTTER ACTIVATION IS NOT EXPECTED.

SPECIAL WEATHER STATEMENT
Issue Date: 329 PM CST TUE DEC 01 2009
Expiration: 330 AM CST WED DEC 02 2009

...POSSIBLE WINTER WEATHER EVENT ON FRIDAY FOR SOUTHEAST TEXAS...
AN UPPER LEVEL DISTURBANCE IS EXPECTED TO MOVE ACROSS TEXAS AND
INTO SOUTHEAST TEXAS ON FRIDAY. MUCH COLDER AIR WILL ALSO FILTER
INTO THE REGION DURING THE DAY AS THIS DISTURBANCE MOVES OVER THE
AREA. STRONG LIFT ASSOCIATED WITH THE DISTURBANCE WILL COMBINE
WITH ENOUGH MOISTURE AND COLD AIR SO THAT WINTER PRECIPITATION
WILL BE POSSIBLE ACROSS SOUTHEAST TEXAS DURING THE DAY FRIDAY.
PRECIPITATION WILL POSSIBLY START AS RAIN BUT CHANGE TO SNOW
DURING THE DAY AS TEMPERATURES FALL. THIS SCENARIO REMAINS RATHER
UNCERTAIN SINCE THERE IS STILL SOME QUESTION AS TO WHEN THE
DISTURBANCE MOVES OVER THE REGION AND HOW MUCH MOISTURE WILL BE
AVAILABLE FOR WINTRY PRECIPITATION. FORECASTERS WILL CONTINUE TO
MONITOR FORECAST DATA AND MAKE CHANGES AS NECESSARY. RESIDENTS OF
SOUTHEAST TEXAS ARE ENCOURAGED TO MONITOR THE FORECAST AND LOOK
FOR UPDATES CONCERNING THE WINTER WEATHER THREAT.
