KEY MESSAGES

Issued at 212 PM CST SAT NOV 7 2026

- Frost and Freeze Potential: Chances are medium to high for frost development across portions of the area Sunday and Monday mornings, especially across the far northern counties and the Black Belt. There will be a low chance for a light freeze in the typically colder locations.

DISCUSSION

(This afternoon through Friday) Issued at 212 PM CST SAT NOV 7 2026

Mostly clear and calm conditions will allow for prime radiational cooling overnight tonight. Lots of forecast lows tonight in the 30s across central Alabama, including mid 30s in many areas. Decided to pull the trigger on a Frost Advisory overnight across the whole area, as there are bound to be microclimates that will see near ground air temperatures near freezing. We'll probably see a repeat of these conditions tomorrow night as well.

We will remain dry through the start of the upcoming work week, with surface high pressure in control. An upper level shortwave trough is forecast to scoot across the southern tier of the nation on Wednesday, which could help squeeze out a few showers Wednesday into early Thursday. This is quickly followed by another larger upper shortwave that digs into the southeast states and helps drive a cold front through our area late Thursday. More cold temperatures filter in behind this front, perhaps even colder than the present system by a few degrees.

AVIATION

(18Z TAFS) Issued at 1142 AM CST SAT NOV 7 2026

Visual meteorological conditions are forecast across central Alabama over the 24 hours. I suppose there is a low chance of some transient light fog in the usual areas (namely TCL) overnight tonight, but the computer model guidance suggests even that chance is too low to include in the TAFs for now. Thus, we are left with primarily a wind forecast with no cloud expected below 12000 ft.

FIRE WEATHER

High pressure will keep conditions free from rain through Tuesday. A fast moving disturbance will bring low rain chances Wednesday through early Thursday. Another cold front passage will lower temperatures and increase wind speeds the end of the week.
