KEY MESSAGES

Issued at 508 AM CST FRI NOV 6 2026

- Fog: There's low to medium chances for patchy dense fog in valleys and along rivers late tonight into early Friday morning.

- 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

(Friday through next Thursday) Issued at 1025 PM CST THU NOV 5 2026

The cold front remains over our far SE counties this evening and will continue to push southeastward overnight. Dense fog has developed right along and ahead of the front, and a Dense Fog Advisory has been issued for Pike and Barbour Counties. Some improvement is expected behind the front, but with light winds, low dew point depressions, and recent rainfall, at least patchy ground fog is expected to develop across the forecast area overnight into Friday morning. A shortwave trough will also move through the area but only produce some high clouds, while an upper low moves southeastward over the eastern Great Lakes. A secondary, dry cold front associated with this feature will move through the area on Friday. This will result in cooler lows Friday night, but winds should stay up enough to prevent any frost concerns. A brief shot of slightly below normal high temperatures is then expected for Saturday. Surface high pressure will result in favorable radiational cooling conditions Saturday and Sunday nights. Chances for frost are medium to high across the far northern counties and Black Belt, with a low chance for a light freeze in the typically colder locations. Frost advisories will likely be needed when this gets closer.

No significant weather systems are forecast through early next week. The forecast area will generally be between the subtropical and polar jet streams. A southern stream shortwave does move across the area during the Tuesday/Wednesday timeframe. This may squeeze out some virga/sprinkles/very light rain, but low-level moisture return will be lacking and probabilities of measurable rain will remain at 10 percent or less. A strengthening ridge across the western and central CONUS will lead to amplification of a longwave trough across the eastern CONUS later in the week.
