Area Forecast Discussion
National Weather Service Peachtree City GA
239 PM EST Tue Dec 12 2017



.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.
