KEY MESSAGES

Updated at 935 AM CST Fri Nov 13 2026

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

NEAR TERM

(Tonight) Issued at 240 PM CST Fri Nov 13 2026

Surface high pressure situated over western Ontario was producing a northerly flow across much of the eastern Lower-48. Lower level moisture within the flow was also bringing lower altitude clouds across the region. Mostly cloudy to cloudy skies were more common north of the Tennessee River, while mostly sunny to partly cloudy conditions prevailed elsewhere. With cloud cover attenuating direct sun, area temperatures ranged from the low/mid 40s north to mid 50s south. A few echoes that were producing light showers were moving southward across middle and eastern Tennessee. This activity was fading as it moved further southward.

Overall cloud coverage should fade somewhat as we go into the evening. Colder air associated with the high will make its presence felt tonight, as lows fall into the upper 20s to lower 30s. This growing season ending cold snap help warrants a Freeze Warning, which continues for our Alabama counties tonight and Saturday night. Lighter winds than last night, and the fact that more cold air is in place will make for a chilly night. Cloud coverage diminishing should enhance a colder trend as well.

SHORT TERM

(Saturday through Sunday) Issued at 935 AM CST Fri Nov 13 2026

The upper level pattern this weekend shows a large trough across most of the CONUS east of the Rockies. With sfc high pressure settling into the Southeast, dry and cold conditions are in store this weekend. Afternoon highs will warm into the mid to upper 50s on Saturday and Sunday with overnight lows Saturday night in the mid to upper 20s. Once again a Freeze Warning has been issued for our northern AL counties due to a high chance for a hard freeze.

LONG TERM

(Sunday night through Thursday) Issued at 917 PM CST Thu Nov 12 2026

Upper troughing that was holding strong over the eastern third of the CONUS should begin moving off the East Coast, as upper ridging slowly builds in from the west. This will help bring a gradual warming trend far as temperatures for the new week. Expect another chilly Sun night with lows from the upper 20s to mid 30s, and highs Mon in the mid/upper 50s. A slow warming trend can be expected as we go further into next week. Lows will range in the 30s, with highs in the lower 60s Tue, and in the mid/upper 60s on Wed/Thu respectively. At this time, dry conditions should prevail into next Thu.

AVIATION

(18Z TAFS) Issued at 1143 AM CST Fri Nov 13 2026

Widespread stratus over the Great Lakes and Midwest will continue advecting southward across the TN Valley. Limited daytime heating has resulted in CIGs rising to above 3000' AGL (MVFR/VFR threshold) across northern AL, while MVFR CIGs continued over portions of southern Middle TN. Those CIGs should rise to VFR during the early afternoon. Cloud bases should remain above MVFR threshold into the late afternoon, with scattered low/id clouds expected afterwards. NNW winds of 5-15kt and some higher gusts will diminish to around 5kt tonight. NNE winds around 5kt are expected a few hours after daybreak Sat.
