KEY MESSAGES

Updated at 121 PM CST Sun Nov 8 2026

- A Frost Advisory has been issued for all counties in northern Alabama and southern middle middle Tennessee from 11 PM tonight through 7 AM CST on Monday. Low temperatures will fall into the low to upper 30s tonight.

- A low chance of patchy frost is also forecast Monday night into early Tuesday morning.

NEAR TERM

(Tonight) Issued at 121 PM CST Sun Nov 8 2026

Tranquil weather across the Tennessee Valley this afternoon with high pressure building into the region. Current satellite imagery does show some high cirrus moving into portions of the area (mainly south of the AL/TN border), but these clouds will have little impact on our sensible weather as ample heating today has warmed temperatures into the low to mid 60s in most spots. These clouds may stick around for most of the evening and portions of the overnight hours, but they won't do anything to stunt radiational cooling due to the dry air mass and light winds. This will allow temperatures will fall into the mid to upper 30s in most locations (with a few localized valleys reaching the freezing mark). These cool temperatures will likely result in areas of frost late tonight into early Monday morning and for this reason we have opted to issue a Frost Advisory for the entire Tennessee Valley from 11 PM tonight to 8 AM Monday. Those with sensitive plants should take precautions to cover them or bring them inside.

SHORT TERM

(Monday through Wednesday) Issued at 1057 AM CST Sun Nov 8 2026

The upper low/associated surface low over Texas will be slow to move east on Monday. Models continue to show slight upper level ridging building over the area. The guidance also keeps cloud cover southwest of the area through much of the day. The result should be sunny skies (not even many high clouds more likely) and warming temperatures with highs climbing into the upper 60s to lower 70s.

As the upper low/associated surface low moves further east into Arkansas and northern Louisiana Wednesday night, thicker cloud cover should move into the area ahead of it. Not expecting any precipitation at this time, due to a very dry boundary layer remaining in place. Frost is not out of the question given current guidance, so kept with NBM lows in the 35 to 45 degree range mainly (particularly southern middle Tennessee and NW AL). However, this may end up being too cold as we receive future guidance.

As the upper low weakens and broadens out to an open trough axis feature aloft, stronger forcing continues to push into the area. Low and mid level moisture/warm air advection continues. However, with more cloud cover expected, highs may stay in the upper 60s to lower 70s.

LONG TERM

(Tuesday night through Saturday) Issued at 937 PM CST Sat Nov 7 2026

A powerful trough will be digging into the eastern CONUS Wednesday into Thursday. This will bring a sharp cold front through Wednesday night or Thursday. Only a low chance of a shower or thunderstorm exist with the front before blustery north-northwest winds occur behind the front. After highs in the 60s Thursday, overnight lows will dip into the lower to middle 30s Thursday Night. Highs on Friday will only reach the lower 50s in valleys and upper 40s atop the Cumberland Plateau. This will be about ~15 degrees below normal. The first widespread freeze of the season will take place Friday night into Saturday morning with lows in the upper 20s to around 30. High pressure will shift southeast into the Gulf States late Saturday, with overnight lows in the upper 20s to lower 30s.

AVIATION

(00Z TAFS) Issued at 456 PM CST Sun Nov 8 2026

VFR conditions are forecast through the TAF period at both KMSL and KHSV with calm winds. A low chance of patchy fog is forecast in portions of the area early Monday morning. There is too low of confidence to include this in the official TAF package at this time.
