DISCUSSION

(Thursday through next Wednesday) Issued at 1141 PM CST WED NOV 4 2026

This trough and cold front will continue to slowly push through the region, with some lingering showers in the forecast in our SE zones through today. Winds behind the front are already going calm, with areas of fog developing given the recent rainfalls. This fog is expected to be very dense at times, with a Dense Fog advisory in effect until 9 AM Thursday.

Temperatures this weekend behind the front will quickly begin to drop, as cool dry air filters down from the Midwest. Afternoon highs will generally range in the upper-60s and low-70s, with overnight lows dropping into the low to mid-40s. Lows in some locations are even expected to drop into the mid and upper-30s in the coming days, with frost confidence increasing to medium during this time. This frost will not be a "one off" either, as the pattern will likely support frost potential into the middle of the new workweek.
