.NEAR TERM...
(Tonight)
Issued at 205 PM CST Tue Nov 25 2025

Model trends continue to decrease our severe threat through the
remainder of the afternoon. Cloud cover has been slow to clear in
NE AL prompting some CIN to remain through mid day and dissuading
the NE progression of CAPE from central AL. As such, despite our
significant shear, our severe potential will be greatly limited
through the afternoon due to the overall lack of instability. From
12Z-18Z CAMS have decrease our forecast surface CAPE through the
afternoon from near 1000 J/KG to below 500. While this is still
enough to support some rumbles of thunder and gusty winds, the
probability in seeing a severe warning issued has decreased
significantly. Even with the decreasing severe threat, showers and
storms will still progress through NE AL along a pre frontal
trough axis and exit around 6 PM.

Overcast conditions will likely prevail through the night keeping
our overnight lows in the high 40s. Winds will veer slightly to
the west with surface high pressure approaching. This will begin
our CAA with dew points and temps slowly dropping through the
night.

.SHORT TERM...
(Wednesday through Friday)
Issued at 1018 AM CST Tue Nov 25 2025

Surface high pressure will build behind the front and remain
dominant through the short term forecast. This will present a
significant pattern change from or recent warm days as NNW flow
along the base of high pressure will usher in much cooler and
drier continental air. As high pressure builds in the northern
Plains, NNW flow will be maintained through the end of the week.
This will significantly drop both temperatures and dew points. Dew
points look to drop through the day on Wednesday from the 50s to
the high 20s. Temperatures will see a similar drop through the day
on Wednesday with our high temps in the low 50s likely being
observed before noon with temps steadily dropping through the
afternoon. The remainder of the week will maintain these cool
temps with highs in the 40s on Thursday and Friday and overnight
lows in the 20s and 30s.

.LONG TERM...
(Friday through Monday)
Issued at 1010 PM CST Mon Nov 24 2025

As we dive into the weekend, dry and warming conditions are forecast
under the influence of sfc high pressure residing over the Southeast
US. High temperatures are forecast to reach the 40s on Friday before
warming into the mid 50s by Sunday. Saturday night, sfc high
pressure begins to shift eastward as an upper level trough begins to
slowly push into the Mississippi Valley, bringing medium chances of
showers on Sunday and Monday. As an upper level closed low pushes
more eastward towards our area, a cold front is forecast to bring
increased shower chances (50-60%) ahead of it Monday evening into
Tuesday. Due to this system being almost a week out, we will have to
continue to monitor trends throughout the week. However, as of now,
looks to be showers with potentially heavy rainfall. If you have
post- holiday travel plans early next week, check back in for
forecast updates as we approach the weekend!

Issued at 504 PM CST Tue Nov 25 2025

VFR conditions are forecast to continue, however, they will be
relatively short-lived as low cloud cover pushes into the TN
Valley from the west overnight. This will result in MVFR
conditions at both KMSL and KHSV during the early morning hours on
Wednesday. VFR conditions are forecast to return by the late
morning. Additionally, there is a low chance of fog impacting both
terminals overnight and it may be added to the next update.
