AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
317 PM EDT SUN JUN 22 2008

.SHORT TERM /TONIGHT THROUGH TUESDAY NIGHT/...
THE WEAK SURFACE TROUGH HAS SHIFTED SOUTHWARD TO
ALONG A LINE FROM CARROLLTON TO MACON TO WINDER. THIS TROUGH IS
ACTING AS A FOCUS FOR CONVECTIVE DEVELOPMENT WITH SCATTERED
THUNDERSTORMS HAVE OVER CENTRAL GEORGIA THIS AFTERNOON AND ISOLATED
STORMS ACROSS PORTIONS OF NORTH GEORGIA. BOTH GFS AND NAM SHOWING
CAPES IN THE 1500-2000 RANGE AND LIFTED INDICES OF -3 TO -6 OVER
PORTIONS OF EAST AND CENTRAL GEORGIA THIS AFTERNOON. CONVECTION
SHOULD START TO DIMINISH WITH THE LOSS OF HEATING.

LONG WAVE TROUGH SHIFTS EASTWARD THROUGH FORECAST PERIOD. THE
SHORT TERM MODEL START OUT IN FAIRLY GOOD AGREEMENT AND START TO
DIVERGE AFTER 12Z MONDAY. GFS BRINGS THE BASE OF THE LONGWAVE
ACROSS NORTH GEORGIA SLIGHTLY FASTER TOMORROW AFTERNOON AND IS A
BIT STRONGER WITH THE STRENGTH OF THE VORTICITY MOVING ACROSS NORTH
AND EAST GEORGIA MONDAY NIGHT. THIS MAY BE BECAUSE OF CONVECTIVE
FEEDBACK. NAM DEVELOPS A SURFACE LOW ALONG THE BASE OF THE TROUGH
AND WILL CONTINUE SLIGHT CHANCE OF STORMS AS BETTER UPPER LEVEL
FORCING AND INSTABILITY ARE EAST OF THE FORECAST AREA...HOWEVER
THERE WILL STILL BE SOME MOISTURE PRESENT. WEAK RIDGING BEGINS
BUILDING INTO THE AREA ON TUESDAY WITH SOME DRYING NOTED.

GUIDANCE TEMPERATURES WERE RUNNING COLD THE LAST SEVERAL DAYS SO
HAVE GONE WARMER THAN GUIDANCE FOR OVERNIGHT LOWS. AFTERNOON HIGHS
WILL BE SLIGHTLY WARMER THAN NORMAL THROUGH MIDWEEK AND DID NOT
STRAY TOO FAR.

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
ALTHOUGH THE UPPER RIDGE BEGINS TO BREAK DOWN ON WEDNESDAY...DRY
CONDITIONS WILL PERSIST.  THE SURFACE HIGH ALSO SHIFTS EASTWARD
ALLOWING GULF MOISTURE TO RETURN ON THURSDAY.  DEEP MOISTURE SETS UP
ACROSS THE AREA THROUGH THE REMAINDER OF THE EXTENDED PERIODS...
WHICH WILL LEAD TO DIURNALLY DRIVEN THUNDERSTORMS ENHANCED BY WEAK
IMPULSES MOVING THROUGH THE UPPER LEVEL FLOW AS AN UPPER LOW TRACKS
ACROSS SOUTHERN CANADA INTO NORTHERN NEW ENGLAND BY SUNDAY.
