DISCUSSION

(Sunday through next Saturday) Issued at 1039 PM CST SAT NOV 7 2026

We are cooling off nicely this evening with temperatures already down into the upper 40s to mid 50s. Lows in the mid 30s, light winds, and narrowing dew point depressions will promote patchy frost across the region late tonight through roughly 7 AM Sunday morning. Similar conditions are expected Sunday night into Monday morning so we will likely see another Frost Advisory issued as we wrap up the weekend.

Dry air and surface high pressure will keep us dry as we head through the first half of the work week. The upper level pattern starts to pick up a bit by mid week with a southern stream trough lifting across the Southern Plains. Enough moisture looks to pool across the region ahead of this feature to warrant a low chance of rain late Wednesday through Thursday afternoon. A stronger upper level trough quickly rips across much of the eastern US Thursday through the weekend. An associated cold front will be sent our way on Thursday with a reinforcing surge of high pressure arriving over the weekend. Limited moisture will lead to a dry FROPA with this late week system.

Temperatures will slowly warm through the work week with highs rebounding into the low to mid 70s by Tuesday/Wednesday. Thursday's cold front will bring another shot of cooler air to the region with highs struggling to break out of the 50s. Lows will plummet into the low to mid 30s next week. Latest NBM probabilities hint at 50-70% chance of seeing freezing temps across our northern counties Saturday and Sunday mornings.

FIRE WEATHER

Afternoon RH values through early next week will remain in the 30- 40% range. A slight uptick in moisture will increase min RH values into the 40-50% range for most of the region. Rain chances briefly return late Wednesday through Thursday. Otherwise, we will remain dry. Light winds will help negate fire weather concerns.
