AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
233 PM EDT TUE SEP 3 2013

.SHORT TERM /TONIGHT THROUGH WEDNESDAY/...
SLOW MOVING COLD FRONT ACROSS N GA IS EXPECTED TO STALL ACROSS THE
CENTRAL TO S GA AREA ON WEDNESDAY. AFTERNOON RADAR HAS ISOLATED TO
SCATTERED SHOWERS AND STORMS DEVELOPING FROM ABOUT ATL-AHN AND S AND
THIS SEEMS TO LINE UP WITH THE BEST INSTABILITY. ACTIVITY IS
EXPECTED TO ENDING THIS EVENING WITH THE LOSS OF DAY TIME HEATING.

BEST CHANCES FOR WEDNESDAY LOOK TO BE ACROSS CENTRAL GA WHERE AFTERNOON
HEATING WILL GENERATE SOME INSTABILITY...MOST SO ACROSS THE SOUTHERN
PORTION OF CENTRAL GA CLOSEST TO THE FRONT.

DURING THIS PERIOD THE MAIN UPPER LEVEL TROUGH AXIS WILL SHIFT EAST
OF THE AREA AND THIS SHOULD DECREASE THE POSSIBILITY OF SHORT WAVE
ENERGY HELPING ANY CONVECTION.

FORECAST LOW TEMPERATURES RUNNING NEAR NORMAL TONIGHT FAVORING A
MODEL BLEND. FORECAST HIGH TEMPERATURES RUNNING NEAR NORMAL FOR
WEDNESDAY FAVORING THE COOLER MET.

OVERALL CONFIDENCE IS MEDIUM TO HIGH

BDL

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
FOR THE EARLY PART OF THE LONG TERM...HAVE TAKEN OUT THE POPS FOR
THURSDAY OVER CENTRAL GA. IT APPEARS ALL THE MODELS ARE PUSHING THE
FRONT SOUTH OF THE CWA AND SPREADING THE DRY AIR FURTHER INTO THE
STATE. OTHERWISE...NO OTHER CHANGES PLANNED. PREVIOUS LONG TERM
DISCUSSION FOLLOWS...

LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
/ISSUED AT 357 AM EDT TUE SEP 3 2013/
MODELS CONSISTENT IN KEEPING DRY AIR ACROSS NORTH GEORGIA THROUGH
THE END OF THE WEEK AS THE FRONTAL BOUNDARY STALLS JUST SOUTH OF
THE CWA. DRYING ALOFT AND LOW PRECIPITABLE WATER SHOULD KEEP
CONVECTION OUT OF MUCH OF THE CWA THROUGH THURSDAY NIGHT...EXCEPT
FOR SLIGHT CHANCE AFTERNOON AND EVENING ALONG THE LAST ROW OR TWO
OF COUNTIES SOUTH OF COLUMBUS TO MACON. MOISTURE BEGINS SPREADING
BACK INTO THE FORECAST AREA ON FRIDAY AS LOW LEVEL WINDS TURN TO
THE EAST AND SOUTHEAST. HOWEVER WITH UPPER RIDGE BUILDING OVER THE
SOUTHEAST STATES THROUGH THE END OF THE PERIOD...EXPECTING ONLY
LOW CHANCE OR SLIGHT CHANCE AFTERNOON AND EVENING THUNDERSTORMS
ACROSS THE AREA.
