.SHORT TERM...
(This afternoon through Tuesday)
Issued at 136 PM EST Mon Dec 8 2025

Could we see a break from the dreary conditions today? Maybe! Rain
from last night has made its way well out of the area, though
lingering cloudy conditions remains behind the front. The good news
is that winds have begun to pick up signally a change to post
frontal conditions and clouds should continue to lift and dissipate
over the coming hours. The rate at which we clear will determine
exactly how warm our temps get today, however we will likely remain
on the low end of forecast highs for today given how models tend to
handle the timing of regime changes like this.

No more precipitation is expected through Wednesday morning and
continued dry air will hopefully give us some sunny afternoons from
here out. Tomorrow morning could see a brief return to dreary cloudy
conditions with near surface winds briefly bringing weak wedge
conditions, however low level flow could quickly recover returning
to SW by tomorrow afternoon as the sfc high moves eastward. Dry
conditions and potentially sunny afternoons may drive greater
diurnal temperature swings with lows each night in the 30s and highs
climbing into the upper 50s tomorrow (depending how fast we shift
the wedge out of here). Either way, the weather will remain
relatively benign through the short term outlook.

.LONG TERM...
(Wednesday morning through next Sunday)
Issued at 136 PM EST Mon Dec 8 2025

To kick off the long term forecast period on Wednesday, much of
southern CONUS will be situated under northwesterly flow at the mid-
levels. Expect this pattern to continue well into the weekend, owing
to persistent troughing across eastern Canada and the Great Lakes. A
stronger shortwave traversing the broader flow around the base of
the trough will kick a (mostly) dry cold front across the forecast
area Wednesday into Thursday, ushering in a brief push of drier air.
Currently, rain chances with the aforementioned front are less than
5%, so expecting minimal impacts to sensible weather before it
fizzles out. Highs will be rather mild, topping out in the mid-50s
to lower 60s.

Dry conditions will linger through at least Friday, when a
disturbance trekking across the Northern Plains into the Midwest
will allow a swath of comparably moist air to clip portions of
northwest Georgia. Global model guidance still exhibits modest
disagreement on the strength of the disturbance (with the Euro
trending stronger and with a more substantial surface mass
response), and it remains be seen if any moisture can be squeezed
out from such weak forcing. For now, trends have favored a drier and
drier solution, with chances for showers at just 10-20% overnight
Friday into Saturday. After a brief return to slightly cooler than
average temperatures Thursday, Friday looks to be the warmest day of
the week, with highs in the mid-50s to mid-60s.

The bigger weather story as we move into the weekend is the
potential for the coldest weather of the season thus far, supported
by an Arctic surface high spreading across the midsection of the
country and settling atop the Southeast. Rather significant spread
exists amongst ensemble guidance, with 25th and 75th percentile high
and low temperatures differing by as much as 15-20 degrees. This
would mean the difference between lows in the teens to near 20
versus lows in the 30s, and highs in the 30s to lower 40s versus
highs in the 50s to lower 60s. For context: the deterministic NBM
forecast temperatures (both high and low!) for Saturday, Sunday, and
Monday are close to/exceed the 75th percentile. The catalyst for
this difference appears to be the proximity of north and central
Georgia to the core of the cold air -- the Euro drags the coldest
air atop the Mid-Atlantic, while the GFS favors the airmass becoming
more diffuse/ taking a more northward path. All this to say: despite
a fairly mild and seasonable work week, this weekend looks to be
cooler, and we may see a significant dip in forecast temperatures as
we approach the weekend as model guidance gets a better handle on
the location of key features.

.AVIATION...
(00Z TAFS)
Issued at 637 PM EST Mon Dec 8 2025

VFR conditions across much of the region as CIGs around 025-040
have finally thinned out. However, guidance has remained
consistent in conditions dropping back to IFR or even LIFR levels
overnight as a large area of 005-015 CIGs moves in from the east,
reaching the ATL area by around 10z and lingering through 15Z.
Conditions improve back to VFR after 16-17z with mostly clear
skies. NW winds currently at 8-10 kts weaken to light and variable
overnight, and turn generally out of the SW at 4-8kts by 18Z
Tuesday.

//ATL Confidence...00Z Update...
Medium to high confidence in the low CIGs overnight. High
confidence for all other elements.
