KEY MESSAGES

Updated at 1010 AM CST Thu Nov 12 2026

- Freeze Watch issued for all of northern AL Saturday morning for temperatures below freezing.

- Hard/killing freeze conditions expected over the weekend with low temperatures in the upper 20s.

NEAR TERM

(Rest of Today and Tonight) Issued at 1010 AM CST Thu Nov 12 2026

A cooler and drier airmass is slowly moving in behind the cold front that pushed through the local forecast area last night. Current temperatures in the lower 50s will warm into the low to mid 60s by this afternoon under mostly sunny skies. Satellite imagery this morning shows another shortwave over the Upper Midwest dropping southward along the western side of an upper level trough. A cold front associated with this shortwave will bring breezy conditions and an increase in cloud cover to the Tennessee Valley with a very low chance of some light rain or drizzle across southern middle Tennessee this afternoon/evening. As the cold front clears the area to the south tonight, a much colder airmass advects in behind it bringing the coldest temperatures of the season. Overnight lows tonight will drop down near freezing across northern AL with upper 20s in southern middle TN. Winds should remain between 5-10 mph through the overnight hours, preventing widespread frost across the area.

SHORT TERM

(Friday through Saturday) Issued at 1010 AM CST Thu Nov 12 2026

Chilly northerly flow sets up across the area on Friday as the post-frontal airmass continues to filter into the area. Under a mix of sun and clouds temperatures will struggle to climb above 50 on Friday afternoon, but it will feel a bit colder with winds gusting 15-20 mph at times. As the winds diminish by Friday night, temperatures begin to plummet down into the upper 20s across southern middle TN to lower 30s in northern AL overnight. The biggest question is will we see our first widespread freeze of the season? NBM probabilities show medium to high chances (50-80%) across most of the forecast area with some lower probabilities near the larger metros and along the TN river. However, REFS probabilities for below freezing temperatures are quite a bit lower with the higher chances along and west of I-65. The reason for these differences is a combination of how fast the cold airmass can move into the area and how quickly the winds weaken to allow temperatures to drop. Given the model run to run consistency of at least part of the area dropping below freezing we have issued a Freeze Watch from midnight through 8 AM Saturday morning. Dry and chilly again on Saturday with afternoon highs only reaching the lower 50s.

LONG TERM

(Saturday night through Wednesday) Issued at 1013 PM CST Wed Nov 11 2026

Bottom line up front: the extended forecast will be dry and pretty cold. Ensure you take care of the 4 P's: People, Pipes, Plants and Pets before, and during the cold.

Later this weekend, the longwave trough that encompasses most of the eastern CONUS will side eastward and a southern stream shortwave will start to undercut it from the Southern Plains. This shortwave will slide eastward and early next week a weak sfc low will develop in the northern Gulf with an inverted trough. Right now, models are keeping rain chances pretty far to our south, providing a dry forecast through Wednesday.

As for temps, they will drop into the 20s Saturday night/Sunday morning, providing a widespread freeze. Sunday afternoon most likely will not reach 60 degrees before falling below freezing again Sunday night/Monday morning. From here we will be on a very gradual warming trend into mid week, reaching the 60s Wednesday afternoon and most of us above freezing Wed night.

AVIATION

(18Z TAFS) Issued at 1121 AM CST Thu Nov 12 2026
