.DISCUSSION...
(Today through next Sunday)
Issued at 205 AM CST MON NOV 24 2025

Today:

Variable cloudiness is expected with high temperatures between
10-15 degrees above normal. A couple climate sites may mange to
reach, or at least come close to, their record for the day.

Tuesday`s rainy and stormy weather:

A shortwave trough located to our west as of early this morning is
forecast to quickly scoot by tonight and be in the vicinity of the
Ohio Valley to Mid-Atlantic region on Tuesday as it becomes
increasingly ill-defined. This will leave us without much in the way
of upper-level support/forcing as showers and thunderstorms affect
central Alabama late tonight through Tuesday; however, with broad
southwesterly jet stream flow arriving and persisting, sheared wind
profiles will be in place with weak to moderate instability
developing during the daytime hours on Tuesday. This setup could
produce a couple severe thunderstorms.

Ongoing showers and thunderstorms to our west today are projected
to arrive to northwest Alabama as early as around midnight and
continue their eastward progression during the overnight hours.
While forecast soundings show a nicely sheared wind profile and
strengthening low-level jet, surface-based instability is shown
to be nil with weak instability aloft. So, much of this activity
will be characterized by downpours and rumbles of thunder.
Considering the upper trough will be at its most conducive
proximity at any point during this event, a low severe risk could
occur along the southern fringe of the activity if sufficient
surface-based instability along the northward-advancing warm front
makes it in time. Should this occur, gusty winds, hail, and a
brief tornado are the potential hazards. This low likelihood
scenario seems to favor counties in the vicinity of Demopolis.

Through Tuesday, we are expected to transition to a speed shear
setup as surface and low-level flow veers. The low-level jet is
also shown to weaken a bit through the day. While ensemble data
show weak to moderate instability developing, the lack of
appreciable upper-level support, and relatively weak frontal
forcing, will temper the severe threat associated with the
multiple bands of showers and thunderstorms. Even so, it is
plausible that a couple severe thunderstorms could manifest given
other environmental parameters (shear, instability). Gusty winds
and hail are the primary hazards, with a lesser potential for a
brief tornado due to the degradation of the low-level flow. All
of this activity should be out of here by early Wednesday morning.

Late week into the weekend:

High pressure begins to build into the region on Wednesday and
will be in control Thursday and Friday. Dry weather is forecast
along with cold mornings and cool afternoons. Thanksgiving Day is
looking nice!

High pressure shifts to the east on Saturday with our next trough
on its approach to the region. The evolution of a broad troughing
pattern with a series of impulses could result in a few days
worth of shower and thunderstorm chances starting on Sunday.

(12Z TAFS)
Issued at 617 AM CST MON NOV 24 2025

Some IFR/LIFR VSBYs/CIGs are present generally across the SRN 1/3
of the state along with some river fog. This may affect TCL/MGM
over the next couple of hours. Otherwise, winds will turn back
around today to the SE/S ahead of our next system. Rain chances
return after 6z along with some MVFR/IFR cigs.

.FIRE WEATHER...

There are no concerns with MinRHs through Wednesday. A drier air
mass will be in place Thursday through Saturday with afternoon MinRHs
reaching the 30s for much, if not all, of central Alabama.
Locations near and south of the 80 corridor of south-central
Alabama may slip into the 20s during that stretch.

Winds will be near 10 mph with the potential for gusts around 20
mph from the south on Tuesday and from the northwest on Wednesday.

Widespread showers and thunderstorms are expected to affect
central Alabama overnight Monday through Tuesday. This activity
will vacate the region by early Wednesday morning with rain-free
weather forecast from the remainder of Wednesday through Saturday.
Additional rain chances return starting Sunday of next week.
