AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE PEACHTREE CITY GA
731 AM EDT THU OCT 3 2013



.PREV DISCUSSION... /ISSUED 341 AM EDT THU OCT 3 2013/ 

SHORT TERM /TODAY THROUGH FRIDAY/...
EARLY MORNING CLOUD COVER KEEPING FOG DEVELOPMENT POTENTIAL LOW 
ACROSS NORTH GEORGIA...BUT IN THE CLEAR AREAS IN THE CENTRAL AND 
EASTERN PORTIONS OF THE STATE...SEEING PERIODS OF PATCHY FOG 
REPORTED. EXPECT ANY FOG TO DIMINISH JUST AFTER SUNRISE.

THROUGH THE SHORT TERM...THE SURFACE HIGH AND UPPER LEVEL RIDGE LOSE 
CONTROL OVER THE REGION. MODEL SOLUTIONS AGREE WITH DAMPENING OUT 
HIGH ALOFT...AND WITH SURFACE HIGH EAST OF THE STATE...WILL SEE 
DECENT MOISTURE MOVING INTO THE NORTHWESTERN AND NORTHERN PORTIONS 
OF THE STATE. WITH SOUTHEASTERLY FLOW PERSISTING ACROSS THE 
REGION...OROGRAPHIC INFLUENCE SHOULD BE ENOUGH TO SQUEEZE OUT SOME 
LIGHT SHOWERS ACROSS THE NORTHERN CWA. AS A RESULT...HAVE CONTINUED 
WITH MENTION OF SLIGHT CHANCE POPS ACROSS THE AREA. 

EXPECT ABOVE NORMAL TEMPERATURES AGAIN TODAY AND FRIDAY. HAVE 
GENERALLY GONE WITH A BLEND OF THE MODEL GUIDANCE...WHICH CONTINUES 
TO DO WELL IN THIS ENVIRONMENT.

31

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
THE MAIN FOCUS WILL BE ON THE POTENTIAL FOR A TROPICAL SYSTEM TO
AFFECT THE CWA DURING THE LATTER HALF OF THIS COMING WEEKEND. THE
ECMWF IS THE WEAKEST WITH THE GFS BEING THE STRONGEST. THE LATEST
ECMWF IS COMING IN LINE WITH THE GFS AS FAR AS LOCATION IS
CONCERNED. THE CANADIAN APPEARS TO BE A GOOD COMPROMISE...ALTHOUGH
JUST SLIGHTLY TO THE WEST OF THE GFS/ECMWF POSITION. AT THIS
POINT...WHATEVER MODEL IS CHOSEN IT STILL IS POINTING TO A VERY
WET SUNDAY/SUNDAY NIGHT FOR MOST OF THE CWA AND WILL RAISE POPS TO
HIGH LIKELY CATEGORY FOR SUNDAY/SUNDAY NIGHT. DRYING CONDITIONS
SHOULD SPREAD ACROSS THE ENTIRE CWA BY THE MIDDLE OF NEXT WEEK AND
IT SHOULD REMAIN DRY FOR THE REST OF THE LONG TERM AS THE H5 RIDGE
DEVELOPS OVER THE EASTERN U.S.
