KEY MESSAGES

Updated at 935 PM CST Tue Nov 10 2026

- Medium chances (40-60%) for showers and thunderstorms Wednesday evening, primarily along and north of the TN River.

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

NEAR TERM

(Rest of tonight through Wednesday night) Issued at 935 PM CST Tue Nov 10 2026

As sfc high pressure remains dominant over the Tennessee Valley, dry conditions continue overnight with little cloud cover. Coupled with calm winds and low dew point depressions, a low chance of patchy fog exists once again primarily in sheltered valleys and along large bodies of water. Low temperatures are forecast to drop into the 40s through most of the area with some isolated spots dropping into the upper 30s.

Wednesday into Wednesday night, we will be monitoring an upper level trough pushing eastward into the Great Lakes region with an associate sfc low shifting eastward into the Ohio River Valley. A subsequent cold front will be the main talking point as it drops southeastward into the Tennessee Valley Wednesday night into Thursday. Ahead of this front, increased chances (40-60%) of showers with a low chance of thunderstorm development are forecast primarily along and north of the Tennessee River. The main variable to keep an eye on will be the speed of the frontal boundary. Recent CAMs continue to have the main precipitation chances moving through the area between 8-10 PM, with elevated instability and unimpressive lapse rates. If this were to shift into the area more quickly, a low chance of some stronger storms would be on the table with a primary threat of gusty winds. However, a nocturnal arrival continues to be the trend with a more favorable environment for severe weather remaining to our north.

SHORT TERM

(Thursday through Friday) Issued at 935 PM CST Tue Nov 10 2026

Post-frontal conditions bring dry conditions and strong CAA into the area from the northwest with afternoon highs capped in the upper 50s to lower 60s on Thursday. If you think that's chilly, be sure to bundle up on Friday because highs are forecast to remain in the upper 40s to lower 50s. Overnight lows during this short term period are forecast to drop into the 30s throughout the area. Even colder conditions are on the horizon this weekend, which is detailed in the long term forecast discussion below. Be sure to dress in warm layers if venturing outdoors!

LONG TERM

(Friday night through Tuesday) Issued at 935 PM CST Tue Nov 10 2026

Widespread freezes are expected both Saturday and Sunday mornings as a large upper low/trough over the eastern CONUS slowly shifts east. A negatively tilted trough axis will enter the Plains through the western Gulf of America by Sunday. The southern stream Jet will help to strengthen this trough over the Gulf, but also keep surface cyclogensis and the low track in the central Gulf. High pressure will remain a dominant feature over the eastern Great Lakes and OH valley. The combination of the high and low positions will maintain an easterly dry and cool flow across the TN valley. Only slight temperature modifications will result Monday and Tuesday, with highs in the upper 50s to around 60, and lows in the upper 20s to lower 30s in southern middle TN and lower to middle 30s in north AL.

AVIATION

(00Z TAFS) Issued at 516 PM CST Tue Nov 10 2026

VFR conditions are forecast overnight at both sites with calm winds. A low chance of patchy fog exists overnight into early Wednesday, however, confidence is too low to include this in the official TAF package at this time. Winds should increase during the afternoon hours, becoming southwesterly. Gusts up to 18 kts are forecast at KMSL beginning in the late afternoon. Just beyond the TAF period, there's a low chance of LLWS at KHSV. This may be added in future updates.
