KEY MESSAGES

Updated at 816 PM CDT Tue Mar 17 2026

- A Freeze Warning remains in effect through 9 AM Wednesday.

- A warming trend will begin Wednesday and continue through this weekend.

NEAR TERM

(Rest of tonight and Wednesday) Issued at 816 PM CDT Tue Mar 17 2026

Dry conditions are forecast to continue tonight under the influence of sfc high pressure residing over the Ohio River Valley. However, a weak upper level shortwave is forecast to push north of the area - bringing an increase in cloud cover overnight into Wednesday morning. Incoming cloud cover will likely keep low temperatures a few degrees warmer than previously forecast, remaining in the low to mid 30s. A Freeze Warning remains in effect for all of northern AL through 9 AM Wednesday, the aforementioned shortwave allows low chances (15% or less) of rainfall through portions of the area (primarily NW AL) during the morning to early afternoon hours. Conditions should improve during the late afternoon as cloud cover departs the area gradually from west to east. High temperatures are forecast to reach the mid to upper 50s.

SHORT TERM

(Wednesday night through Friday) Issued at 816 PM CDT Tue Mar 17 2026

A gradual warming trend is forecast through the short term period as upper level ridging begins to shift eastward into the area. Highs are forecast to reach the upper 60s to lower 70s on Thursday and will be comfortably in the mid 70s by Friday afternoon. The only feature to watch in the short term will be a weak frontal system Thursday, which will likely remain dry due to lack of forcing as well as dry conditions.

LONG TERM

(Friday night through Tuesday) Issued at 816 PM CDT Tue Mar 17 2026

Upper level ridging and subsequent sfc high pressure continue to influence the region through the weekend into early next week. In turn, dry conditions are forecast to continue along with above- normal temperatures. High temperatures this weekend will likely be in the upper 70s to low 80s (potentially reaching the mid 80s in some spots Sunday) under sunny skies. These temperatures are around 15 degrees above normal for this time of year, however, no record breaking temperatures are expected. The high temperature records for March 22nd are 88 degrees at HSV and 89 degrees at MSL, both set in 1907. A cold front will likely form and shift southward through the area Sunday night into Monday morning, which will allow relatively cooler temperatures early next week with highs in the 60s-70s.

AVIATION

(06Z TAFS) Issued at 1240 AM CDT Wed Mar 18 2026

Surface high pressure situated over the Appalachians will move off of the Mid Atlantic coast today. Thus, light winds overnight will becoming southerly today. Expect S-SW winds of 5-10kt with a few stronger gusts in the afternoon. Greater mid and higher altitude moisture moving in from the NW will produce mainly broken, to at times overcast conditions from higher altitude clouds. VFR weather otherwise should continue for the TAF.
