KEY MESSAGES

Updated at 1013 PM CST Wed Nov 11 2026

- A line of sub-severe showers and storms will continue moving east through the overnight hours.

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

NEAR TERM

(Rest of tonight and Thursday) Issued at 1013 PM CST Wed Nov 11 2026

A line of showers and embedded thunderstorms can be seen moving through the TN Valley currently by radar. Most of the thunderstorm activity has remained north of the TN/AL state line, and thunderstorm chances will stay low through the overnight hours due to a limited thermodynamic environment. As the cold front pushes through the area, breezy winds should keep any fog development at bay through the early morning hours. Overnight lows will be in the mid 40s.

Cooler air will continue to move into the area tomorrow in the wake of our first cold front, while a second, reinforcing cold front pushes south through the lower OH River Valley. Temps will be noticeably cooler on Thursday with highs about 10 degrees colder, topping out in the lower 60s. Northwest winds will also be breezy throughout the day with wind gusts up to 20-25mph at times.

SHORT TERM

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

Even colder air will arrive tomorrow evening/night as the reinforcing front pushes through the area. Overnight lows will fall to near or below the freezing mark by Friday morning, with northwest winds bringing wind chills down to the mid 20s in some locations. While some locations may reach 28 degrees or cooler, confidence in widespread hard freeze conditions is not high enough to warrant a Freeze Watch at this time.

Friday will be dry and mostly sunny, but temperatures will struggle to make it to the 50 degree mark in most locations due to the strong cold air advection. Hard freeze conditions are likely across much of the area Friday night and a Freeze Watch may be issued in future forecast updates. Similar conditions are forecast on Saturday, with sunny skies and highs in the lower 50s. Be sure to break out those winter jackets and protect the four Ps: People, pets, plants, and pipes!

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

(06Z TAFS) Issued at 1228 AM CST Thu Nov 12 2026

A cold front (and related thin band of low-topped convection) has exited the local forecast area as of 6Z, with WNW flow of 5-10 kts and few high-based Cu expected for the early morning period. Shortly after sunrise, a tight pressure gradient and steepening low-level lapse rates will support an increase in NW flow to 12G20 kts, with winds expected to veer to NNW after 2Z as a secondary, reinforcing cold front spreads southeastward through the region. Although VFR conditions will likely exist for the duration of the TAF period, the presence of cold air aloft will support development of a broken VFR stratocu field beginning after sunrise, with cigs expected to be in the 5-7 kft range thru the end of the period.
