.KEY MESSAGES...
Updated at 200 AM EST Fri Dec 12 2025

- Significant rainfall is not anticipated in the region through
the end of next week.

- An Arctic front will produce colder temperatures Sunday and
Monday with lows potentially in the teens. Temperatures rebound
quickly through the second half of the week.

.SHORT TERM...
(Today through Saturday)
Issued at 200 AM EST Fri Dec 12 2025

Dry conditions through the near term outlook. Upper level flow out
of the NW as a broad upper level trough traverses ECONUS. Mostly
clear conditions and drier air means temps will fall quickly
overnight with lows this morning crisply in the 30s. Highs each
day will rebound quickly, given the clear and dry conditions as
well as decent low level SW flow.

Conditions don`t change significantly going into the weekend. A
shortwave feature riding the subtropical jet may be enough to prime
some moisture ahead of our next system with some weak and very brief
southwesterly ll-flow. Any moisture that does make it`s way into the
area will be shallow and of highly dependent on the length of time
in which 950-700mb flow remains SW.

.LONG TERM...
(Saturday night through Thursday)
Issued at 200 AM EST Fri Dec 12 2025

On Saturday night, a closed mid-level low will be moving
southeastward through the Great Lakes region, with troughing on the
southern side swinging through the eastern CONUS. As this occurs, an
associated surface low over Southeast Canada will extend a cold
front through the Midwest and into the Tennessee Valley region.
Isolated to scattered showers are forecast to spread into northwest
Georgia on Saturday night. As the front advances southward into the
area, scattered showers (with PoPs between 25-45%) will overspread
much of the forecast area after midnight and through the morning
hours on Sunday. As this front pushes through we will see temps
begin to dip down into the upper 20s and low 30s over far north and
northwest Georgia in the early morning. Isolated precipitation (~10%
PoPs) lingering behind the front could thus potentially combine with
near freezing temperatures for a very light rain/snow mix. However,
we are not expecting any accumulations at this time as temps will
have been warm ahead of the front. Rain chances are then forecast to
diminish with the front weakening as it moves south and east into
central Georgia during the daytime. Rainfall amounts ahead of the
front appear to be negligible - at most about 0.10 inch. Rain
chances and totals are anticipated to be highest across the western
portions of the forecast area.

As mid-level troughing clears Georgia to the east and the front
exits the area, an Arctic surface high will move Missouri/Iowa
towards the Southeast. There is the potential for significantly
colder air to set up late Sunday into early next week in association
with this high. The extent of how much temperatures will drop will
depend on the movement of the high`s center and the proximity of
north/central Georgia to the core of the coldest air. Recent model
runs have been reasonably consistent in indicating the high`s center
will track across the Tennessee Valley region early Monday, and
towards the South Carolina/Georgia coast by early Tuesday. This
favors a greater drop in temperatures by by early Monday morning.
Low temperatures on Monday morning are forecast to drop into the
teens in north Georgia and low 20s in central Georgia. Wind chills
could furthermore drop into the single digits in the higher
elevations of far northeast Georgia. Confidence continues to
increase in these temperatures given more run to run consistency in
the guidance, though the evolution and track of the Arctic high will
still need to be monitored.

Monday will be a brisk day throughout, with highs being limited to
the low 40s across the majority of the area. With dewpoints in the
single digits on Monday afternoon, RH values will approach minimum
values of 25% or below on Monday afternoon, and thus a Fire Danger
Statement may be needed. Guidance also continues to indicate the
weakening of the high late Monday into Tuesday, which would serve to
moderate the airmass as it begins to move towards the Atlantic. Low
temperatures on Tuesday will still be well below normal, in the low
20s across much of the forecast area. Highs will then rise into the
upper 40s to low 50s in far north Georgia and mid 50s in central
Georgia. The influence of the high will furthermore inhibit
precipitation through mid-week, though a quick increase in
temperatures and dewpoints can be expected ahead of the next system,
which will bring a chance of showers late Wednesday into Thursday.
