KEY MESSAGES

Issued at 254 PM CDT Mon Sep 7 2026

- Chances are increasing for a weather pattern change that delivers cooler temperatures by this weekend.

DISCUSSION

Issued at 254 PM CDT Mon Sep 7 2026

Yet another day continues with ridging as the predominant weather influence over the Four State Region. Each day, convection continues to percolate along the patches of vorticity propagating in westward flow around and between ridge axes. Today's patch will ride along the edge of a weak frontal boundary with the ridge axis centered across the southern Great Plains. This frontal boundary will linger across the area into Tuesday before drifting back north as a warm front by the middle of the week, leaving a drier day for Wednesday before the next patch of moisture and vorticity lines up with an approaching frontal boundary by Thursday. A gradual cooldown ensues as a result of this activity (mid 90s), while long-range guidance suggests a pattern change by the end of this week (temperature maximums likely cooler in the low-to-mid 90s) as the aforementioned ridge finally breaks down, bifurcated by troughing with an attendant frontal boundary that is expected to arrive later next weekend with more widespread rain chances. Resulting WPC QPF Day 1-7 values reflect an overall a precipitation distribution that is trending wetter in southeasterly zones with 0.01 to 0.25 inch rainfall totals likely areawide and 0.25-0.50 inch totals more likely to the south where any additional convection can form. /16/
