KEY MESSAGES

Updated at 1026 AM CST Wed Dec 10 2025

- Breezy winds 10-15 mph with gusts up to 35 mph will occur today.

NEAR TERM

(Tonight) Issued at 100 PM CST Wed Dec 10 2025

It's been a mild and quite breezy day. West southwesterly winds have remained below Wind Advisory criteria with gusts reaching 20-30 kts. Overcast skies are scattering out in NW AL and that trend will spread eastward into this afternoon. Wind gusts will weaken as we go through the late afternoon and evening, but won't diminish until after midnight when they veer to become northerly behind the passage of a cold front. Temps will be about 10 degrees colder than last night, falling into the mid to upper 20s.

SHORT TERM

(Thursday through Saturday) Issued at 1026 AM CST Wed Dec 10 2025

Off to a cold start Thursday morning with temps in the mid to upper 20s. Behind the cold front that will pass through Wednesday night, higher pressure will spread in and keep northwesterly winds around for most of the day on Thursday. This will provide a brief cool down with highs in the low to high 40s despite mostly sunny skies. Friday will see the warm up as high pressure glides through and returns southwesterly flow 5-10 kts with gusts up to 15-20 kts. While we sit in high pressure on Friday, a sfc low will ride through the OH Valley and pull a weak front into the TN Valley Friday night and return northerly flow. Winds will be light, however overnight lows will be around freezing. Saturday will be tranquil and mild with highs in the low to mid 50s, however precip chances return Saturday night along with a blast of arctic air. More on that in the Long Term below, and stay updated with the latest forecast for this weekend as we get closer.

LONG TERM

(Friday night through Tuesday) Issued at 1052 PM CST Tue Dec 9 2025

High pressure at the surface will promote fairly tranquil conditions Friday night into Saturday, with zonal flow continuing aloft. This will result in another fairly mild day on Saturday with high temperatures reaching the mid to upper 50s once again. A weak shortwave will bring another cold front through the area. Modest moisture return ahead of this feature should allow for some low chances (20-30%) for light precipitation Saturday night, before rapidly tapering off between 09-12z Sunday morning. Depending on the timing there could be a brief window for precipitation to mix with snow (with no impacts), but for a vast majority of locations think this will remain a cold rain -- with precipitation ending by the time the subfreezing air arrives.

A much colder air mass will arrive on Sunday, with highs struggling to climb much above the 40 degree mark. Then, a clear, cold, dry night will knock lows into the upper Teens to lower 20s Sunday night. This colder air mass will quickly begin to modify monday and Tuesday as high pressure builds in and winds veer back to a southerly direction. This will allow highs to climb back to seasonable norms.
