.SHORT TERM /Tonight through Wednesday Night/...
Short term forecast relatively benign. Cold front moving through the 
state will bring drier and cooler air to the state into late week. 
Increased cloud cover this afternoon is already starting to 
dissipate over north Georgia as the front makes forward progress. 
Tight pressure gradient is producing high winds, and Wind Advisory 
remains in effect until 10 PM tonight. Expect wind speeds to 
diminish somewhat overnight, and more significantly Wednesday as the 
gradient relaxes. Temperatures will make a return to the 20s 
Wednesday morning, with highs in the 40s to low 50s. A gradual warm 
up is expected into the long term, with lows on Thursday in the 30s.

.LONG TERM /Thursday through Tuesday/...
A dry cold front will move slowly south across the CWFA during the 
day on Thursday, and finally push into the Florida panhandle by late 
Friday. High pressure will briefly build in for Saturday, but the 
high center should move offshore by early Sunday as a low pressure 
center from the western GOM moves onshore. Abundant moisture is 
expected just ahead of the system, and rain chances should begin to 
increase late Sunday into Monday. There are still some differences 
in the models, but the ECMWF and GFS both show high PoPs across the 
NW corner of the CWFA by Sunday night. 

No major changes to most elements within the long term forecast 
period. However, did bump pops up Sunday night into Monday.
