Area forecast discussion 
National Weather Service Peachtree City Georgia 
312 PM EDT sun Sep 7 2008 


Short term /tonight through Tuesday night/... 
remnants of a weak cold front continue to dissipate over central 
Georgia this afternoon. Isolated to scattered convection firing up 
south of this boundary where moisture is a bit more abundant. 
Precipitation chances should be confined to the southern third of the 
forecast area this evening. Monday...the old front has washed out and 
moisture is at least marginal for isolated afternoon convection 
across the entire forecast area. Better rain chances appear to be on 
tap for Tuesday as the tail end of another cold front...associated 
with a low in the more active northern branch of the upper level 
flow over the upper Midwest and Great Lakes...slips into north 
Georgia. Still... with the region under the western end of the large 
western Atlantic ridge...anything over chance probability of precipitation seems to be 
wishful thinking. 


Long term /Wednesday through Sunday/... 
models keep the basic upper level pattern over the U.S. Relatively 
unchanged through the majority of the extended forecast period with 
the southeastern states under the western end of the large western 
Atlantic ridge. A much more active...although shallow...northern 
branch has little effect on our weather outside of dragging the weak 
tail ends of a couple of cold fronts into the region. This pattern 
also keeps Ike on a more westerly path where it should have little to 
no effect on Georgia until possibly very late in the extended 
forecast period when the upper level pattern amplifies somewhat and a 
relatively deep western U.S. Trough helps kick Ike rapidly northeast 
after landfall somewhere in the northwestern Gulf of Mexico. 
However...the models do seem to want to keep a moderate amount of 
low and middle level moisture over the region through the extended 
forecast period...so I will keep the current trends of seasonal 
temperatures and scattered showers and thunderstorms relatively 
unchanged in the extended forecast.
