.DISCUSSION...
(Thursday through next Wednesday)
Issued at 1144 PM CST TUE DEC 23 2025

Deep ridging in place over the Gulf Coast region will contribute to
well above average temperatures over the next several days with a
significant airmass change expected early next week.

Tonight, advection fog is quickly spreading northward from the
Gulf Coast. Current obs are showing 1/4 mile visibilities across
southwestern AL. HREF probabilities also indicate high chances
(70-80%) of reaching Dense Fog Advisory criteria across our
southern counties, so I went ahead and issued the advisory through
9 AM. To our north, a weak front will stall east to west across
the Tennessee Valley, and we are seeing low-level cloud cover
across our northern counties associated with that, but the
boundary will remain well to our north and no rain in expected. In
fact, the airmass will remain quite dry through the week. We`ll
be in shorts and t-shirts for Christmas with daytime highs in the
mid 70s and overnight lows in the 50s.

Early signals indicate the ridge will break down by this weekend as
a more organized upper-level trough advances across the Northern
CONUS and towards the Great Lakes region. A surface low will develop
over the Central Plains and rapidly eject towards Ontario at the
start of next week, so we`re expecting an associated cold front to
bring rain to Central Alabama in the Sunday/Monday timeframe.
Behind the front, a strong northwesterly blast of Winter air will
bring a rapid end to our shorts and t-shirts weather.

.AVIATION...
(06Z TAFS)
Issued at 1144 PM CST TUE DEC 23 2025

Advection fog continues to move north towards MGM. VFR conditions
persist for now, but expect some impacts to develop within the next
several hours, primarily at the southern terminals. Low-level clouds
across the north are not expected to produce reductions in flight
criteria. Visibility will improve after sunrise, and VFR conditions
are expected through the day with a light westerly wind.

.FIRE WEATHER...

Southerly winds will continue to increase today, ushering in
plenty of moisture from the Gulf. MinRH values will generally
range above 50% into next weekend, with mixing heights adjusting with
the cloud cover. No organized rain chances are anticipated
through the workweek, with drought conditions persisting for the
foreseeable future. Lower RH are anticipated behind the front on
Monday and will need to keep an eye on the winds as RH values will
be in the 20s.
