KEY MESSAGES

- A drier airmass across the region will yield less humid conditions, with closer to normal highs, and cool lows.

DISCUSSION

Issued at 201 AM CDT Wed Sep 23 2026

Today through next Tuesday...A frontal boundary will continue to slowly sink south through the forecast area today. During the afternoon hours today, as highs warm into the middle 90s across mainly southern portions of the CWA, a stray shower or storm can't be ruled out in the vicinity of this boundary. The remainder of the forecast area will remain dry as highs warm into the low and middle 90s.

In the wake of the aforementioned frontal boundary, noticeably drier air will filter into the region and remain across the region into at least early next week. High pressure aloft and at the surface will also assert itself into the region through the beginning of the weekend. Rain chances will essentially be nil across the area during this time. High temperatures each day will be a bit less than they've been in recent weeks, as they range from the upper 80s to low 90s Thursday through Saturday. Some gradual warming will then ensue Sunday through Tuesday, as highs peak in the low and middle 90s. The result of the drier airmass across the region will especially be felt during the night time hours as lows fall into the 60s.

Once again, rain chances will remain tough to come by during most of this forecast period. Ridging aloft will weaken enough on Sunday, allowing a disturbance embedded in northwest flow to traverse the CWA. This will bring some isolated showers to the forecast area Sunday. Then late Monday into Tuesday, a shortwave dropping southeast into the region will yield another chance for rain across the forecast area Tuesday into Tuesday night. /19/
