.SHORT TERM...
(This afternoon through Sunday)
Issued at 153 PM EST Sat Dec 20 2025

With benign quasi-zonal flow aloft and exiting high pressure at the
surface, abundant sunshine and mild conditions are expected to
continue today. Under clear skies, expect highs today to be several
degrees warmer than yesterday, in the upper 50s to mid-60s areawide.
As the aforementioned surface high slides eastward across the Mid-
Atlantic and off of the Eastern Seaboard over the course of the day
today, surface winds will veer to the east, and then further to the
southwest overnight, ushering in a warmer, more moist airmass from
off of the Gulf. Slowly rebounding moisture will prevent
temperatures from dropping quite as much tonight, with Sunday
morning lows in the mid-30s to lower 40s.

To round off the weekend, a weak front riding along the leading edge
of a stronger surface high pressure system nosing southeastward
across the Northern Plains and into the Midwest will clip the
western half of the forecast area. Very low-end (15-20%) chances for
light rainfall and increased cloud cover are all that is expected
from the glancing blow. Currently not forecasting any meaningful
accumulation, and it`s possible that only some patchy drizzle is
realized for areas west of the Metro. With much drier air filtering
in behind the front, any rain chances should be contained within the
daybreak to midday timeframe, and most will remain completely dry.
Highs Sunday will be warmer still, generally in the 60s to near 70 --
about 5 to 10 degrees above average.

.LONG TERM...
(Monday morning through next Friday)
Issued at 153 PM EST Sat Dec 20 2025

The bulk of the forecast period will be characterized by abnormally
warm temperatures for December alongside continued mostly dry
conditions. The exception to the very warm conditions will be at
the start of the week on Monday as surface high pressure along the
Mid-Atlantic coastline will bring CAD-like easterly flow and keep
high temperatures closer to normal in the 50s to low 60s.

Beyond Monday, the big warmup begins as subtropical ridging builds
in earnest and becomes anchored across the center of the country
through the week. This will promote temperatures some 15-20 degrees
above normal, bringing highs in the 70s for the vast majority of the
area by Christmas Eve into Christmas Day. In fact, low temperatures
in the 50s will be closer to normal late December highs. While
current forecast highs are still a couple degrees below the records
for Christmas Eve and Christmas Day, at the very least we`re likely
looking at a top 5 warmest Christmas on record for the area.

.AVIATION...
(18Z TAFS)
Issued at 1234 PM EST Sat Dec 20 2025

VFR and SKC to continue thru the evening, with cigs gradually
deteriorating to BKN MVFR by 13-14Z. Lifting to FEW-SCT VFR is
then expected by 16-17Z. DZ and perhaps -RA may accompany lowest
cigs, but confidence is currently too low for TAF mention. Winds
initially light (<7kts) out of the SE will go CALM/VRB overnight,
but will generally favor the W side aft 05-06Z.

//ATL Confidence...18Z Update...
Medium confidence AM ceiling progression and low-end precipitation
chances.
High confidence all other elements.
