KEY MESSAGES

Updated at 1145 AM CST Fri Nov 6 2026

- Low temperatures will fall between freezing and the middle 30s Sunday morning, with higher confidence Sunday night into Monday.

- Patchy to widespread frost is possible if winds can decouple early Sunday and Monday mornings, but confidence is low to moderate.

NEAR TERM

(Rest of Today and Tonight) Issued at 1145 AM CST Fri Nov 6 2026

An upper-level low near New York state and an attached cold front draped to the south and west is currently making its way across the forecast area. Current temps will not have much more time to warm ahead of the front and highs in most places will top out in the upper 60s to low 70s before CAA takes place area wide later this afternoon. For tonight, a pressure gradient will cause winds to be in the 5-10 mph range with possibly higher gusts. This in combination with some spotty cloud cover should keep frost out of the forecast for most areas with forecast lows expected to be 34-38 in sheltered locations with higher lows in the upper 30s to low 40s elsewhere. Winds should act to keep chances of fog formation low overnight.

SHORT TERM

(Saturday through Monday) Issued at 1145 AM CST Fri Nov 6 2026

During the day on Saturday, an area of surface high pressure is expected to build southeast toward the forecast area. With temps starting out in the 34-40 degree range and continued CAA from the north, daytime highs will only manage to reach the upper 50s to low 60s. With a relaxing pressure gradient, lighter winds are expected and low temps should drop into the low to mid 30s (with the lowest temps expected in southern middle TN and NW AL). This could result in fairly widespread frost in those locations with some areas possibly dropping below freezing. A Frost Advisory or Freeze Watch may eventually be needed for mainly NW AL.

Heading into Sunday temperatures are expected to get a little warmer with abundant sunshine and weaker CAA. Current highs are forecast to be around 65 degrees for most spots. With calm winds and clear skies forecast much of Sunday night, this will be another night we need to watch for possible widespread frost and localized freezing temps across the area. Further frost/freeze products may be needed. Further weakening of CAA and sunshine on Monday will allow temps to further moderate into the upper 60s to low 70s.

LONG TERM

(Monday night through Friday) Issued at 215 PM CST Fri Nov 6 2026

Most guidance forecasts weak upper level ridging to develop briefly over portions of central Alabama and much of Georgia Monday night in response to an upper low aloft moving through eastern Texas into NW Lousiana. Some weak westerly to slightly southwesterly low level flow will likely bring a bit more moisture in the area. This will likely help to limit further freeze potential. Cloud cover remains much closer and just east of the upper low. Thus, clear skies and light winds should allow for some frost to occur still, but should not be as widespread as previous nights. Currently, low temperatures are expected to drop into the mid 30s to lower 40s primarily.

During the day on Tuesday, models differ on how quickly the upper low pushes east and how much it weakens. Either way though, would expect general warm air advection in low levels to be in place ahead of it over northern Alabama. Cloud cover also is not very certain this far east. Given expected low level moisture and temperature advection expected, highs should continue to warm during the day into the 65 to 70 degree range in most locations (despite any cloud cover).

Models continue to diverge concerning the evolution of the upper low Tuesday afternoon through Wednesday. Expect more cloud cover Tuesday afternoon or evening and generally steady state temperatures during that period. Either way, the forecast looks precipitation free during that period.

Model guidance does start to converge more towards a stronger longwave trough axis rotating southeast from the Upper Midwest late Wednesday afternoon into Wednesday night. How much this phases with a secondary trough axis to its south over Texas is in question in guidance (which would lend itself to a wetter solution and more cloud cover further east later).

A large area of high pressure behind this longwave trough axis is shown in most guidance. This originates from north central Canada. This could bring even colder air southward into the area towards the end of the week into the following weekend. This looks like it could be the coldest air of the season so far.

AVIATION

(00Z TAFS) Issued at 456 PM CST Fri Nov 6 2026

BKN to OVC decks of low stratus will continue to push into the Tennessee Valley from the north this evening, creating borderline MVFR/low-end VFR conditions with ceilings around 3 kft. Winds will remain out of the NW around 10 kts. Clouds will gradually scatter out as ceilings lift to VFR levels by Saturday morning.
