SPECIAL WEATHER STATEMENT
Issue Date: 549 AM CST THU DEC 3 2009
Expiration: 330 PM CST THU DEC 03 2009
...THE POTENTIAL FOR WINTRY PRECIPITATION WILL EXIST FOR MOST AREAS
FRIDAY NIGHT...
A STRONG UPPER LEVEL TROUGH WILL MOVE ACROSS THE DEEP SOUTH FRIDAY
AND FRIDAY NIGHT. A COLD AIRMASS IS ALREADY ESTABLISHED OVER THE
REGION AND WILL PROVIDE THE POTENTIAL FOR AREAS OF SNOW OR A
WINTRY MIX OF PRECIPITATION FRIDAY NIGHT.
AN ALL SNOW LINE WILL BEGIN TO MOVE INTO THE AREA FROM THE
NORTHWEST AROUND SUNSET FRIDAY AND SHOULD BE LOCATED ALONG A LINE
FROM BAYOU SORREL TO HATTIESBURG MISSISSIPPI BY MIDNIGHT. THIS
INCLUDES THE BATON ROUGE METROPOLITAN AREA. A SNOW SLEET MIX
SHOULD EXIST ALONG A LINE FROM THIBODAUX TO SAUCIER MISSISSIPPI AT
MIDNIGHT INCLUDING THE NORTHSHORE OF LAKE PONTCHARTRAIN. A RAIN
SLEET MIX SHOULD EXIST ALONG A LINE FROM HOUMA TO OCEAN SPRINGS
MISSISSIPPI BY MIDNIGHT...INCLUDING THE SOUTHSHORE AREA OF
METROPOLITAN NEW ORLEANS...GULFPORT AND BILOXI. ACCUMULATIONS OF
ANY WINTRY MIXED PRECIPITATION ARE EXPECTED TO BE NO GREATER
THAN ONE INCH WITH THE BEST CHANCES FOR ACCUMULATIONS ALONG AND
NORTHWEST OF A LINE FROM THIBODAUX TO SAUCIER MISSISSIPPI.
THE LARGEST PROBLEM ASSOCIATED WITH THIS EVENT WILL BE THE POSSIBILITY
OF PRECIPITATION FREEZING ON ELEVATED ROADWAYS BECOMING A TRAVEL
HAZARD. WINTER WEATHER ADVISORIES MAY BE NECESSARY LATER TODAY OR
EARLY FRIDAY.
