KEY MESSAGES

Issued at 532 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.
