AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
305 PM EDT TUE SEP 27 2011

.SHORT TERM /TONIGHT THROUGH THURSDAY/...
WEAK SLOW MOVING COLD FRONT ACROSS CENTRAL GA THE MAIN CONCERN.
PLENTY OF MOISTURE AND INSTABILITY ASSOCIATED FOR SCATTERED SHOWERS
AND THUNDERSTORMS ACROSS CENTRAL GA INTO TONIGHT. OVERALL ACTIVITY
SHOULD DIMINISH OVERNIGHT BUT MAY NOT COMPLETELY END DUE TO WEAK
SHORT WAVE ACTIVITY.

BEST CHANCES FOR SHOWERS/THUNDERSTORMS WILL BE OVER CENTRAL GA FOR
WEDNESDAY...MAINLY IN THE AFTERNOON/EVENING. THE BEST AREA WILL
GREATLY DEPEND ON HOW FAR S THE FRONT GETS OVER THE CWA AND WHEN.

MOISTURE AND INSTABILITY LOOK TO DIMINISH FOR THURSDAY WITH THE
AFFECTS OF THE FRONT SHIFTING EAST AND SOUTH OF THE AREA...SO NO
POPS WILL BE IN THE FORECAST FOR THURSDAY. A DRY OR MOSTLY DRY COLD
FRONT MOVES INTO N GA THURSDAY NIGHT. AT THIS TIME...NO POPS WILL BE
IN THE FORECAST.

FORECAST LOW TEMPERATURES RUNNING 4 TO 7 DEGREES ABOVE NORMAL
TONIGHT GENERALLY FAVORING THE WARM SIDE OF GUIDANCE....AND CLOSE TO
NORMAL WEDNESDAY NIGHT. FORECAST HIGH TEMPERATURES RUNNING 3 TO 5
DEGREES ABOVE NORMAL FOR WEDNESDAY AND THURSDAY GENERALLY TAKING A
MODEL BLEND.

OVERALL CONFIDENCE IS MEDIUM.

.LONG TERM /FRIDAY THROUGH TUESDAY/...
NO CHANGES PLANNED TO THE LONG TERM. A DRY/MOSTLY DRY COLD FRONT
MOVES ACROSS THE AREA FRIDAY WITH DRY HIGH PRESSURE MOVING TO/OVER
THE AREA SATURDAY THROUGH TUESDAY. LOOK FOR TEMPS TO BE NEAR TO 10
DEGREES BELOW NORMAL MOST PLACES.
