KEY MESSAGES

Issued at 1243 PM CDT THU SEP 3 2026

- Significant Heat Risk: Heat indices will remain in the 105-108 degree range each afternoon through at least Saturday, and a Heat Advisory remains in effect.

DISCUSSION

(Thursday through next Wednesday) Issued at 1132 PM CDT WED SEP 2 2026

Upper-level ridging will remain steadfast to start this forecast period, as the center of it remains just to our north. This ridge, and in turn the heat, will remain the main weather story for most of the next week, as afternoon highs will continue to climb into the mid and upper-90s. Heat index values will remain above Heat Advisory criteria during this time, with peak afternoon numbers ranging between 105 and 108 degrees. The existing Heat Advisory remains in effect until 8 PM Saturday. The ridge will slightly break down into the weekend, allowing for a weak disturbance to move in from the Gulf. This should increase rain chances for a portion of the forecast area, but confidence here is low regarding the overall impact to heat index values.

By Sunday, the center of the ridge will slide to the west, allowing for at least low-end (20-30%) rain chances to return to the forecast. These rain chances will unfortunately be short lived, as a deep trough begins to take shape over the west coast come Tuesday. This trough will push the apex of the ridge back east, returning it to a location similar to where it currently resides. Afternoon highs should quickly rebound in this scenario, with additional periods of heat headlines running into next weekend.

FIRE WEATHER

Minimum RH values will generally remain above 40% through the work week. Low (10 to 20%) chances for showers and storms will continue daily. Fire weather concerns are currently low, but decreasing soil moisture will begin to raise these concerns by next week given a lack of forecast rainfall.
