KEY MESSAGES

Updated at 1018 AM CST Tue Nov 25 2025

-Strong to severe storms will be possible this afternoon for areas east of I-65 with a threat for damaging winds and a tornado.

-Cooler conditions will build in behind the cold front and remain for the remainder of the week.

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!

AVIATION

(00Z TAFS) 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.
