Area Forecast Discussion
National Weather Service Peachtree City GA
235 PM EST Sun Nov 28 2021



.SHORT TERM /Tonight through Monday Night/...

Large trough is located over the eastern CONUS with several embedded 
shortwaves within the northern and southern portions of the jet. 
Southern disturbance is currently responsible for very light echos 
on radar over central Georgia, most of which isn't reaching the 
ground. Some is reaching, however, so have maintained slight chance 
PoPs through the evening across central Georgia. Otherwise, cold 
front associated with northern disturbance in the jet is progged to 
move into the area through this evening bringing a reinforcing shot 
of cold air, with lows tonight down into the 20s and 30s CWA-wide. 
This front should push any remaining showers or cloud cover out with 
it.

Tomorrow, biggest weather story will be very dry airmass in place 
leading to potential fire weather issues. Thin post frontal surface 
airmass will have very dry air aloft that should be able to mix down 
during the afternoon. This will bring gusty winds, though not likely 
strong enough to warrant full red flag conditions, and very dry air 
to the surface. See fire weather discussion section for more info.

.LONG TERM /Tuesday through Sunday/...

Mid and upper level flow will remain dry and northwesterly for the 
better part of the extended as strong mid level ridging remains 
anchored over the west coast. Will gradually see moisture return as 
surface ridging slides east Tuesday into Wednesday allowing for a 
slight southerly component to the wind and thus a slight increase in 
dewpoints through the week.

Models start to diverge a bit by the weekend, but suggest that 
the west coast mid-level ridge breaks down by Friday allowing the 
flow across the US to become more zonal. Meanwhile a weak 
disturbance approaching by Saturday within the flow allows for the
introduction of low end pops. Still some uncertainty in the model
solutions with the ECMWF a tad wetter than the GFS for Saturday 
with the GFS a little faster to break down the ridge and a little 
dryer with timing differences on the approaching shortwave. 
Nonetheless, sensible weather will be running above average 
through the extended and mostly dry outside of the low end chances
on Saturday.
