Area forecast discussion, Jun 28, 2:23 AM EDT, 1 hour 39 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
223 AM EDT TUE JUN 28 2011

.SHORT TERM /TODAY THROUGH THURSDAY/...
GUIDANCE A LITTLE MORE GENEROUS WITH POPS TODAY AHEAD OF THE COLD
FRONT ALTHOUGH FEEL POPS ARE STILL TOO LOW AND WILL BUMP UP TO
CHANCE/LIKELY WITH THE HIGHEST ACROSS NORTH GEORGIA. A WEAK WAVE IS
CURRENT MOVING ACROSS THE SOUTHERN APPALACHIANS INCLUDING THE
NORTHEAST MOUNTAINS. THIS HAS DEVELOPED A FEW THUNDERSTORMS ACROSS
OUR NORTHEAST MOUNTAIN COUNTIES AND THESE ARE MOVING EAST. THIS WAVE
SHOULD NOT BE A FACTOR BY 12Z. MODELS IN AGREEMENT WITH TIMING AND
LOCATION OF THE SURFACE COLD FRONT...DROPPING INTO NORTH GEORGIA
THIS AFTERNOON...AND MOVING INTO CENTRAL GEORGIA BY WEDNESDAY
MORNING. THIS WILL KEEP THE RISK OF CONVECTION GOING THROUGH
TONIGHT. THE FRONT STALLS ACROSS SOUTH GEORGIA AS A WEAK BACKDOOR
FRONT MOVES ACROSS NORTH GEORGIA ON THURSDAY. THIS WILL BE ENOUGH TO
KEEP SLIGHT CHANCE OF THUNDERSTORMS IN THE MOUNTAINS AND ALSO THE
EXTREME SOUTHEAST PART OF THE CWA DUE TO SEA BREEZE IN THE LATE
AFTERNOON.

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
GFS/ECWMF BUILD A 595 HIGH OVER THE MID MISSISSIPPI VALLEY AT THE
END OF THIS WEEK...SHIFTING THE HIGH INTO KY/TN FOR THE WEEKEND.
THIS WILL BRING THE HOT TEMPERATURES BACK INTO THE CWA. DUE TO THE
PROXIMITY OF THE CENTER OF THE HIGH...THERE SHOULD BE ENOUGH
SUBSIDENCE TO KEEP THUNDERSTORM DEVELOPMENT TO A MINIMUM. THE RIDGE
BREAKS DOWN AND IS REPLACED BY A WEAKNESS IN THE PATTERN WHICH COULD
BE ENOUGH TO BRING A SLIGHTLY HIGHER CHANCE OF PRECIP BY THE END OF
THE LONG TERM.

&&

.AVIATION...
06Z UPDATE...
VFR CONDITIONS SHOULD CONTINUE THROUGH LATER THIS AFTERNOON. MAY
SEE SOME BRIEF PERIODS OF MVFR VSBYS AROUND DAYBREAK BUT IT WILL
BURN OFF BY 13-14Z. EXPECTING MORE AFTERNOON CONVECTION BETWEEN
18Z-00Z WITH CEILINGS AND VSBYS DROPPING TO MVFR LEVEL IN AND
AROUND THUNDERSTORM DEVELOPMENT. WINDS SHOULD STAY MAINLY OUT OF
THE WEST IN THE 5-12KT RANGE.

//ATL CONFIDENCE...06Z UPDATE...
CONFIDENCE HIGH ON ALL ELEMENTS.
