.SHORT TERM...
(This afternoon through Tuesday)
Issued at 116 PM EST Mon Dec 15 2025

Current satellite loop shows clear skies across north and central
GA as high pressure settles in across the area. The models show
this ridge becoming centered over GA/SC by 00z Tue and staying
fairly stationary through Tue afternoon. This ridge does begin to
shift off the GA/Carolina coast by 00z Wed but the ridge axis is
still laying across central GA dominating the weather pattern as
far west as MS. Because this ridge stays across the area for the
next few days it will allow things to warm up. Temps tonight are
still expected to dip back down into the 20s with some teens in
the north GA mountains but highs Tuesday are expected to get back
up to near seasonal norms with highs in the 50s. Lows Wednesday
morning will be in the upper 20s to lower 30s.

.LONG TERM...
(Wednesday morning through next Sunday)
Issued at 116 PM EST Mon Dec 15 2025

Dry conditions and the gradual warm trend continue on Wednesday
as a shortwave ridge slides across the region within low to mid
level southwest flow. The day will start off with morning temps
in the low to mid 30s, which will warm to the mid to upper 50s by
the afternoon despite increasingly overcast skies. This cloud
cover and increased moisture will be an indicator of whats to
come, as our next rain threat will be from mid-day Thursday
through Thursday night. The system driving this will be a strong
mid-level trough and associated frontal boundary ejecting out of
the Plains and sliding across much of the eastern US. As has been
the case with the storm track in recent weeks, the surface low
will remain well off to the north over the Great Lakes region, so
our impacts will be restricted to widespread rain showers and a
few rumbles of thunder. Severe weather is not expected. While we
could see a few areas of light rain Thursday morning, the bulk of
the moisture will surge in Thursday afternoon and evening ahead
of the frontal boundary. Rain will taper off during the overnight
hours on the backside of the front, with dry and cool air
building in on Friday. Rainfall totals for the event look to be
around 0.25-0.5" for most of the area, with a reasonable worst
case of 1.5" across the mountains of north GA.

With the cooler air spreading over the area behind the front,
high temps will only rise to the mid to upper 40s across north
GA, and low to mid 50s in central GA. Friday night into Saturday
morning the surface high will centered over the region, allowing
lows to fall to the upper 20s to low 30s under mostly clear skies
and light winds. As the high shifts off to the east on Saturday,
low to mid-level winds turn out of the southwest, pulling warmer,
moister air back into the region. High temps will warm each day
from Saturday into early next week, with highs on Sunday and
Monday in the mid to upper 60s. Isolated showers will be possible
Sunday and Monday given the moisture over the area.
