.SHORT TERM...
(Tonight through Monday)
Issued at 713 PM CST SAT DEC 21 2024

With clear skies, diminishing northerly winds, and high pressure
extending across the area, temperatures have quickly begun to drop
this evening. Made some tweaks to the trends, but we`re well on
our way to another cold night with lows in the 20s. It will be
chilly again tomorrow despite the sunny skies, but temperatures
will warm into the lower 50s, and winds will be much lower than
they were today.

(This afternoon through Sunday)
Issued at 1058 AM CST SAT DEC 21 2024

This afternoon.

An amplified pattern aloft persists with longwave troughing over
much of the Eastern portion of the country while amplified ridging
extends from over the Four Corners States north to over much of
Montana. Expansive surface high pressure extends from North of
Lake Superior southward to across the Mid-South Region.

Some persistent low clouds have lingered over portions of our
north-central counties into late this morning, but this trapped
moist layer will erode with time as we head through early
afternoon. Skies will range from mostly sunny north to sunny south
by mid afternoon. Winds will remain from the north at 7-14 mph
and will be breezy at times through early afternoon. High
temperatures will range from around 40 far northwest to readings
in the lower 50s southeast.

Tonight.

Longwave troughing will become positioned further east just
offshore of the Eastern Seaboard overnight while amplified ridging
builds eastward over much of the Plains and Midwest. Expansive
surface high pressure becomes centered across the Eastern Great
Lakes.

Look for mostly clear skies overnight with winds decreasing form
the north to 3-6 mph. A widespread freeze is forecast with
readings from the lower 20s northeast to the mid 60s south. Some
of the normally colder sheltered valley locations north and
northeast could dip into the upper teens briefly before sunrise
Sunday morning.

Sunday.

The forecast area will remain under a northwest flow into Sunday
as amplified ridging to our west broadens out with time and as a
shortwave dives southeast out of Canada over the Dakotas during
the afternoon. Elongated surface high pressure will be centered
over Northern New York State and will extend southward into the
Carolinas. Winds will become northeast with speeds from 4-8 mph.
High temperatures will range from the upper 40s north and in the
higher elevations east to readings in the low to mid 50s south and
central.

.LONG TERM...
(Sunday night through next Friday)
Issued at 120 PM CST SAT DEC 21 2024

The surface and upper-air pattern will result in fair-weather
conditions until Tuesday. Through the rest of the week, a series
of shortwave troughs will transit the southern U.S. While models
differ regarding timing and breadth of activity, the general theme
will favor spells of showers Wednesday into the weekend.
Just to our east, persistent surface wedging is suggested by the
GFS/ECMWF/UKMET through Friday. If this setup pans out, it would
tend to limit the quality of moisture return across central
Alabama and, in turn, temper any severe threat. We`ll keep an eye
out for any changes since enhanced flow aloft will accompany these
troughs.

(06Z TAFS)
Issued at 1049 PM CST SAT DEC 21 2024

Calm and clear conditions continue at all terminals through the
morning. High pressure will remain centered over the Northeast, so
a light northeasterly wind around 5 kts will develop tomorrow
afternoon then winds go calm again by 01Z. VFR continues through
this period.

.FIRE WEATHER...

Afternoon minimum RHs will remain above critical thresholds,
generally bottoming out in the lower 30s for parts of central
Alabama over the next few days. 20-foot winds may gust upwards of
20 mph until sundown today from the north, becoming easterly on
Sunday around 5 mph, and southeasterly between 5-10 mph on Monday.
Rain-free weather continues through Tuesday before spells of
showers commence thereafter.
