KEY MESSAGES

- Continued dry ground conditions, gusty winds, and drier air will result in Limited fire danger conditions today and tomorrow. - A light freeze is likely Friday night and Saturday night for areas north of I-20 and east of I-55 especially, but areas of frost are possible across much of the area.

DISCUSSION

Issued at 350 AM CST Thu Nov 12 2026

The predominant feature in the synoptic pattern is a deep upper- level low stretched over the Great Lakes and Canadian Maritimes. A steep ridge centered over the Rockies is therefore resulting in northerly/northwesterly flow into the Gulf South to start out today. Shortwave troughs pivoting through the jet stream around the upper-level low will continue to reinforce cooler and drier air in our region with successive cold fronts into the weekend. The coldest air is likely to arrive by Friday night as a 1025+ mb surface high slips into the Central Plains.

Depending on low-level flow and any cloud cover, a Light Freeze is likely for at least parts of Mississippi north of I-20 and east of I- 55 Friday night and/or Saturday night. Areas of frost are possible farther south and west across most of the area either night with any light winds and clear skies. A Freeze Warning is likely to be issued, though this weekend also marks the climatological average first freeze for may locations. Any headlines would likely be the last for the season as drought has already brought the local growing season to an end. Local hazard graphics have been updated to include an "Elevated" threat for freezing temperatures to highlight the potential for several hours below freezing both nights. Be sure family, neighbors, and pets have a warm place to stay if heating is not available.

Breezy and dry weather in the wake of this morning's cold front will result in Limited fire danger conditions today, and expect drier conditions still tomorrow as winds persist. Local hazard graphic for fire danger was extended through Friday. Heed any local burn bans in place, and avoid open flames or sparks near dry grass and vegetation.

The pattern looks to break down early next week, with a bit of southern jet stream energy carrying a closed low out of the Southern Plains and along the Gulf Coast Sunday into Monday. This will bring some low-end chances for rain on the northern edge of the surface low, but primarily act to disrupt the radiational cooling pattern from the weekend. Confidence in any widespread frost or freeze Sunday night onward is low at this time. /NF/
