KEY MESSAGES

Updated at 1057 AM CST Sun Nov 8 2026

- Low temperatures will fall into the low to upper 30s tonight. 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.

- A low chance of frosty conditions is possible Monday night into early Tuesday morning.

NEAR TERM

(Rest of Today and Tonight) Issued at 1057 AM CST Sun Nov 8 2026

Some thin high cloud cover can be seen developing over much of Arkansas this morning. This is north of thicker cloud cover and deeper moisture producing rainfall near an upper low/associated surface low moving into south central Texas.

Closer to home mainly, we have seen mainly sunny skies accompanied by a chilly start this morning. Temperatures around daybreak dropped into the 30 to 35 degree range mainly in southern middle Tennessee. Further south lows were more variable and highs dropping into the 34 to 40 degree range mainly. Under continued sunny skies these temperatures have climbed back into the 52 to 57 degree range at 10 AM. Starting to see some mixing of drier air aloft down to the surface over the last hour or so as temperatures have climbed to around or above 55 degrees. Based on an average of 6 AM sounding data from BMX and OHX, think this mixing will continue into the afternoon hours. This will likely drop RH values into the 28 to 35 percent range this afternoon. Northeasterly winds should be fairly light maybe reaching 5 to 8 mph this afternoon. Guidance is hinting at some very thin high clouds continue to move east into northern Alabama through the day. This should have little impact on the forecast highs today given the thin nature of this cloud cover and limited coverage. Highs despite a continuing neutral to cold air advection setup should climb into the lower to mid 60s.

The center of a weak area of high pressure will continue to sink east southeast with time tonight. This will likely allow for very light or calm winds over the area later this evening into the daybreak hours on Monday. Though thin cloud cover will be in place this evening to near the AL/TN border, the east southeast push of the surface high should concentrate this cloud cover mainly south of the Tennessee River by the early evening hours. Whether these calm winds extend into far northeastern Alabama is a bit more of a question. Winds may stay up a bit between 3 and 6 mph there. However, if winds become light even for 2 hours or so, we could see fairly widespread frost develop that far east. Therefore, a Frost Advisory has been issued for all of our northern Alabama counties from 11 PM through 8 AM on Monday. Though we may see some lows in NW Alabama drop to or just below the freezing mark, this looks to isolated to warrant a Freeze Watch or Warning.

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

(18Z TAFS) Issued at 1131 AM CST Sun Nov 8 2026

VFR conditions are forecast through much of the TAF period. Northern winds around 5 knots will become calm this evening. For now, some lower VSBYS (MVFR) were included for patchy fog development. Will have to keep an eye out for the possibility of FZFG at KMSL towards daybreak, but confidence is extremely low that will occur.
