Area forecast discussion...updated 
National Weather Service Peachtree City Georgia 
655 PM EDT Thursday Aug 21 2008 


Short term /tonight through Saturday night/... 
GFS/NAM/sref in general agreement through the short term and are 
just a little faster than tpc's track of Fay which has the center 
moving west across North Florida and along the coast of the Florida 
Panhandle and then eventually into Mississippi. The ridge of high 
pressure nosing into north Georgia appears to be strong enough to 
keep Fay from moving into the County Warning Area. However the County Warning Area will not escape 
its effects as we will be caught between the ridge and Fay which is 
creating a strong pressure gradient. This will keep a strong and 
moist easterly flow over the County Warning Area through the short term. The best 
chances of rain from Fay will be along the southern part of the County Warning Area 
through Saturday. It appears the only chance of rain in the northern 
part of the County Warning Area is during the day and a spiral band moves off the 
coast and rotates through the County Warning Area...however on Friday there could be 
some drizzle during the morning hours with the low clouds. With that 
in mind will need to keep a chance of rain over the County Warning Area during the 
day...mainly afternoon...and across the southern part of the County Warning Area at 
night as the precipitation shield pulls toward the center of Fay. Dewpoint 
will remain warm as we will have a tropical atmosphere over the County Warning Area 
which will mean warm overnight lows. Expect mostly cloudy skies due 
to the proximity of Fay...whether it be low level clouds or cirrus 
blow off from Fay. This will keep daytime highs in the 70s and 80s. 


Long term /Sunday through Thursday/... 
long term heavily dependent on the future path of Fay. Models still 
not in agreement of Fay after the weekend. For that reason will not 
change the long term at this time in order to keep consistency.

Aviation...Fay starting to move slowly west...with center expected 
to stay near the Florida Panhandle. Ceilings will be lowering to
