.SHORT TERM...
(This afternoon through Wednesday)
Issued at 226 PM EST Tue Dec 16 2025

Current satellite loop shows clear skies across north and central
GA as high pressure continues to dominate the weather pattern.
The ridge is still centered over central/south GA but it is
beginning to weaken and is still expected to slide off the GA/SC
coast tonight. Even through the ridge center will push off shore
the ridge axis will continue across the state through Wed evening.

As this ridge weakens, the next wave to move in across the state
is beginning to develop along the southern TX Gulf coast. This
next wave stays fairly stationary over the next 24 hours as the
ridge is not allowing it to push eastward. It just continues to
develop along the TX/LA gulf coast before ejecting NE Wed night.
This wave pushes into MS/AL early Thu morning bringing precip to
west GA just after sunrise Thu. For the short term we will mostly
see increased cloud cover Wed/Wed night with the precip moving in
during the extended periods.

With clear skies and the ridge still in control tonight temps
will dip back down to near freezing for most areas. With the ridge
pushing offshore we start to get into warmer southerly flow which
helps the temps to rebound Wed into the upper 50s to lower 60s
across north and central GA. The increased cloud cover Wed
night/Thu morning from the incoming wave will only allow temps to
to get down into the 40s.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 226 PM EST Tue Dec 16 2025

As the long term period begins Thursday morning, a longwave
trough will be moving across the Great Plains towards the
Mississippi Valley. A strong surface low associated with this
trough will meanwhile swing across the Great Lakes region,
extending a cold front towards the Southeast. Amplifying
southwesterly flow ahead of the trough combined with southerly low
level flow will combine to promote continued moisture advection
into central and north Georgia. Morning lows (and dewpoints) will
continue their warming trend from the short term period, starting
Thursday morning in the low to mid 40s across the area. These
dewpoints will increase over the course of the day into the 50s to
near 60 while precipitable water values climb to between 1.1-1.4
inches. Scattered showers will be possible during the morning
hours, becoming more widespread during the afternoon as the
frontal boundary draws closer to Georgia. In spite of these
showers and overcast skies, highs on Thursday will rise to between
5-10 degrees above normal, in the upper 50s to low 60s in north
Georgia and the mid to upper 60s in central Georgia.

The cold front itself is expected to push into the northwest
corner of the state on Thursday night, continuing southeast
through early morning hours on Friday. During the overnight hours,
the combination increased low-level shear ahead of the front and
marginal instability could allow for the development of isolated
thunderstorms. These storms could be capable of producing locally
heavy rain and gusty winds in portions of north Georgia. Rain and
thunderstorm chances will begin to diminish in the pre-dawn hours
on Friday as the front moves into central Georgia and frontal
forcing weakens. Rainfall totals associated with this system have
increased from the previous forecast package, ranging from 0.75-1
inch in the far northern tier and progressively lower to the
south, down to about 0.25-0.5 inch in central Georgia.

Colder air will set up behind this front on Friday, though not
quite to the extent we saw earlier this week. Highs on Friday are
forecast to be in the mid to upper 40s along and north of the I-85
corridor and in the 50s to the south. Low temperatures overnight
into Saturday morning will largely be in the upper 20s to low 30s.
As mid-level ridging slides over the eastern CONUS on Saturday, a
surface high is expected to traverse Georgia and could
potentially set up a a CAD wedge feature that keeps temperatures
in the 50s to near 60 in north Georgia, compared to mid 60s in
central Georgia. A quick- hitting disturbance is likely to swing
through the Tennessee Valley region and into north Georgia
Saturday night into Sunday. At this time, moisture that this
disturbance could tap into appears that it will be limited, with
dewpoints remaining in the 30s to low 40s for much of the
overnight and limited time on Sunday for moisture return.
Ensembles furthermore do not indicate much in the way of rainfall,
and PoPs have been limited to slight chance PoPs in portions of
north and west Georgia on Sunday, as a result.
