Storms and Heat Hit Central U.S. 09-15 to 09-17

Updated Tue Sep 15th 2026, 8:34am PDT

The next few days will bring widespread showers and thunderstorms across the Southern Rockies, Plains, and Missouri Valley. A slow-moving cold front is interacting with a moist and unstable airmass due to a deep cyclone in Ontario, leading to heavy rainfall here. Be prepared for possible flash flooding in areas from northeast Kansas to central Iowa, with a Flood Watch in effect. Severe wind gusts could accompany the most intense storms in the Plains today.

Rain in the Southwest

Southwest and Southern Rockies regions will also see heavy rainfall as monsoonal moisture moves ahead of a strong upper-trough. Keep an eye on local forecasts as conditions can change rapidly.

Florida Rain Showers

A stationary front over the Florida Peninsula means daily downpours, but excessive rainfall isn't expected. Just keep an umbrella handy if you're in that area.

Dangerous Heat Continues

Across the South-Central U.S., late-summer heat persists, particularly in the Southern Plains and Mid/Lower Mississippi Valley. Temperatures will soar into the upper 90s and low 100s. Unfortunately, this hazardous heat will stick around, with Heat Advisories in place from the Texas coastline to the Missouri Bootheel. Expect record-challenging highs in some areas.

Temperature differences today will be notable as well, with cooler air behind the front (70s and upper 60s) contrasted by the hotter temperatures ahead of it.
