Issue Date: 1045 AM EST THU DEC 24 2009
Expiration: 700 AM EST FRI DEC 25 2009
THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH AND CENTRAL GEORGIA.
.DAY ONE...THIS AFTERNOON AND TONIGHT...
STRONG WINDS ARE EXPECTED TO DEVELOP ACROSS NORTH AND CENTRAL
GEORGIA THIS AFTERNOON AND CONTINUE TONIGHT. SCATTERED
THUNDERSTORMS ARE EXPECTED ACROSS PORTIONS OF CENTRAL GEORGIA
TONIGHT. AN ISOLATED SEVERE THUNDERSTORM WILL ALSO BE POSSIBLE
ACROSS THIS AREA.
.SYNOPSIS...
A STRONG LOW PRESSURE SYSTEM IN THE SOUTHERN PLAINS WILL DEEPEN AS
IT MOVES NORTH THROUGH TONIGHT. A COLD FRONT EXTENDING FROM THE
LOW WILL MOVE EAST THROUGH GEORGIA LATE TONIGHT.
.PRIMARY HAZARDS...
STRONG WINDS FROM THE EAST MAY CAUSE SOME DAMAGE TO TREE LIMBS OR
WEAKENED TREES. HIGH PROFILE VEHICLES SHOULD USE CAUTION ON NORTH
TO SOUTH HIGHWAYS AND ROADS. SCATTERED THUNDERSTORMS IN CENTRAL
GEORGIA MAY CAUSE CLOUD TO GROUND LIGHTNING. THE BEST LOCATION
FOR THUNDERSTORMS IS GENERALLY ALONG AND SOUTH OF A LINE FROM
HAMILTON...TO FORSYTH...TO ATHENS.
.DISCUSSION...
THE PRESSURE GRADIENT BETWEEN HIGH PRESSURE TO THE NORTHEAST AND THE
DEEPENING LOW WILL INCREASE THIS AFTERNOON...LEADING TO WIND SPEEDS
AROUND 20 MPH WITH GUSTS UP TO 40 MPH THROUGH TONIGHT.
AS THE COLD FRONT APPROACHES TONIGHT...CAPES WILL INCREASE UP TO
300 ACROSS PORTIONS OF CENTRAL GEORGIA. WITH THE UPPER-LEVEL SUPPORT
PROVIDED BY THE APPROACHING SYSTEM...THUNDERSTORMS MAY DEVELOP
ACROSS CENTRAL GEORGIA. STRONG VERTICAL WIND SHEAR WITH EAST WINDS
AT THE SURFACE AND SOUTHWEST WINDS ALOFT...MAY ALLOW AN ISOLATED
THUNDERSTORM TO BECOME BRIEFLY SEVERE. STRONG DAMAGING WINDS AND
LIGHTNING WILL BE THE MAIN THREATS...BUT WITH THE STRONG SHEAR AN
ISOLATED BRIEF TORNADO CANNOT BE RULED OUT.
ANY PROLONGED OR STEADY RAINFALL THAT DEVELOPS THIS AFTERNOON AND
TONIGHT MAY LEAD TO ADDITIONAL RISES ON ALREADY FULL CREEKS AND
RIVERS. A FEW LOCATIONS MAY EXPERIENCE SOME MINOR FLOODING.
.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY...
NO HAZARDOUS WEATHER IS EXPECTED AT THIS TIME.
.SPOTTER INFORMATION STATEMENT...
