KEY MESSAGES

Updated at 837 PM CST Fri Nov 13 2026

- Freeze Warning issued for all of northern AL Saturday morning and Sunday morning for temperatures below freezing.

NEAR TERM

(Rest of tonight and Saturday) Issued at 837 PM CST Fri Nov 13 2026

A broad upper trough over the eastern CONUS continues to send shortwaves rippling SE from the Great lakes into the Ohio Valley and Mid South. These features are bringing some reinforcing shots of cool air into the Tennessee Valley. A broad area of stratus (ceilings 3-4 kft) have oozed into the region this evening and these clouds could persist through a good portion of the night (though drier air is eroding them somewhat in areas along and west of the I-65 corridor). As a result, temperatures may remain a degree or two high in some spots -- regardless though, it's going to be a cold night with temperatures falling into the upper 20s to lower 30s in most locations. Many areas will experience their first freeze of the season and as a result a Freeze Warning is in effect for all of northern Alabama from Midnight to 8 AM CST.

Drier air will erode what clouds are left by early Saturday morning and as a result a dry and sunny day will be in store for the area on Saturday. Despite the sunshine, it will be quite cool again thanks to the persistent northerly flow reinforcing this air mass. Daytime highs will resemble January instead of mid- November, with temperatures only peaking in the low to mid 50s and wind chills remaining in the 40s for most of the day. Make sure you bundle up if you have any outdoor plans.

SHORT TERM

(Saturday night through Monday) Issued at 837 PM CST Fri Nov 13 2026

Another good setup for radiational cooling Saturday night in this cool, dry air mass as temperatures should drop like a rock underneath a clear sky. As a result, a widespread hard, killing freeze is expected with lows in the mid to upper 20s being common. Another Freeze Warning is in effect Saturday night into early Sunday morning. This widespread freeze should be enough to end our Autumn Frost-Freeze program. High pressure will build in from the north early next week, resulting in mostly sunny and tranquil weather both Sunday and Monday. Despite the sunshine though, temperature will remain on the cool side with highs in the mid to upper 50s being common both days.

LONG TERM

(Monday night through Friday) Issued at 837 PM CST Fri Nov 13 2026

At the start of the new work week, a cut off low will be plunging through the southeast. The low looks to pass to our south on Monday, before dampening and dissolving into the larger scale troughing over Florida on Tuesday. We currently look to be too far north of this feature to see any significant impacts beyond just some increased cloud cover.

By Tuesday afternoon, mid level ridging will begin to build in from the southwest, accompanied by surface high pressure building over the Ohio Valley. Through the remainder of the week, subsidence from high pressure will work to keep skies dry and clear. Under mostly clear skies, temps will enter a weak warming patter rising from highs in the low 60s to start the week to the low 70s by Friday. Low will follow a similar rebound warming from the 30s on Monday night to the mid 40s by Thursday night.

AVIATION

(06Z TAFS) Issued at 1025 PM CST Fri Nov 13 2026

VFR flight weather conditions are forecast at both KMSL and KHSV. However, spotty MVFR ceilings will occur through the next few hours in southern middle TN and far northeast AL. Overall, the trend will be for ceilings to dissipate in the 10-14Z timeframe.
