.SHORT TERM...
(This afternoon through Wednesday)
Issued at 141 PM EST Tue Dec 23 2025

Forecast Considerations through Christmas Eve:

The main point of interest in the forecast through Christmas Eve
will be the unusual warmth. Tonight`s low temperatures will be in the
50s, meaning that most of north and central Georgia will start off
Christmas Eve with temperatures that are already close to average
high temperatures. Westerly winds will bring WAA during the day and
by the time the afternoon arrives 70 degree temperatures will be
widespread. The record high for Atlanta is 73 degrees (set in 2016),
and this should get replaced with a new record (90% chance). Daily
record highs are more robust at the rest of the regional climate
sites (Athens 77 degrees, Columbus 79 degrees & Macon 77 degrees),
but several of these could fall as well. Of the three Macon has the
best odds of reaching a new record, right around an 84% chance. All
the probabilities here are derived from NMB guidance. The primary
bust factor in the forecast is cloud cover. More clouds than
forecast would reduce the potential for record highs, while fewer
would increase in the potential for multiple records to fall.

Some patchy dense fog is possible tonight south of Columbus, but in
general the westerly surface flow should keep the needed Gulf
moisture focused over south Georgia. Impacts are possible for
anyone traveling to southern Georgia tomorrow morning.

.LONG TERM...
(Thursday morning through next Monday)
Issued at 141 PM EST Tue Dec 23 2025

The long term period will pick up on Christmas Day with continued
warm temperatures across the region. A broad 500 mb ridge over the
Great Plains will advance towards the eastern CONUS while surface
high pressure moves across the northern Gulf coast. This high
pressure regime will keep unseasonably warm temperatures in place
into the weekend. Lows on Christmas morning will largely start
out in the low to mid 50s across north and central Georgia. Aside
from highs in the mid to upper 60s in the highest elevations,
highs will then rise into the mid to upper 70s in the afternoon.
These high temperatures will be 15-23 degrees above daily normals,
and could furthermore push record high temperatures at our four
main climate sites (Atlanta, Athens, Macon, and Columbus). These
low and high temperatures will remain fairly consistent through at
least Saturday. Late Friday into Saturday, a shortwave and
associated surface low will move across the Ohio Valley region,
which could spread isolated to scattered light showers into
portions of far north Georgia, though rainfall amounts are
expected to be negligible.

By late Saturday, the persistent mid/upper level ridge will have
broken down and will be replaced by a more progressive flow pattern.
Ensemble guidance continues to indicate the merging of the
subtropical and polar jet streams, which could bring a jet streak
across the Great Lakes and Ohio River Valley on Sunday. A quickly
developing surface low will then extend a cold front through
Tennessee  and towards the Lower Mississippi River Valley during the
daytime on Sunday. As the low moves northeastward, the front is
anticipated to push into far north Georgia Sunday night, advancing
southward through the overnight hours into Monday morning. Scattered
showers will be ongoing ahead of the front, with chances diminishing
early Monday as the front weakens in central Georgia. Model
uncertainty remains on how much instability will be present in the
warm sector overnight, which will determine the chances of
thunderstorms along with these showers. Noticeably colder air will
set up on the back side of the front, first in far northwest
Georgia by Monday morning, then across the entire forecast area by
Monday afternoon.

.AVIATION...
(18Z TAFS)
Issued at 1221 PM EST Tue Dec 23 2025

Patchy MVFR ceilings (1000 to 3000 ft AGL) will be possible in
north Georgia through 18Z Wednesday, but in general VFR
conditions with ceilings above 4000 ft AGL should prevail. Winds
will continue to be out of the west (220 to 300 degrees) at 2 to 8
kt through 18Z Wednesday as well. Patchy fog is possible south of
KCSG after 09Z Wednesday, but the odds of occurrence at KCSG are
very low (less than 10%).

//ATL Confidence...18Z Update...
Moderate confidence in the ceiling forecast, with the uncertainty
focused on the potential for MVFR ceilings between 09Z and 15Z
Wednesday.
High confidence in all other elements of the forecast.
