Weather Story

Showers and Storms Increasing Overnight

Slow moving Heavy Rain Tonight & Monday

Severe Weather Risk Wednesday & Thursday

Heat and Humidity Build Around Midweek

Showers and storms will continue to expand across SE Iowa, NE Missouri and WC Illinois through 3 AM. Rainfall rates of an inch or more per hour are likely. This will lead to ponding water on roads. A localized flash flood threat will exist for areas that see repeated rounds of heavy rainfall.

After several rounds of heavy rain earlier Sunday, additional showers and storms are expected Sunday night through Monday evening. Abundant moisture and slow movement means that extended periods of heavy rain will occur, leading to localized flash flooding. Some gusty winds may also be possible with stronger storms.

A strong cold front plowing into a hot and humid airmass will set the stage for a risk of severe storms Wednesday and Thursday. Many details are still unknown at this time, but continue to check the forecast for updates on this risk in the coming days!

A period of hot and humid conditions is likely Tuesday and Wednesday. Heat index readings could be around or over 100 degrees. There will also be a chance for storms later Tuesday night that will bring some uncertainty in the temperature forecast for Wednesday, so stay tuned for updates regarding this potential period of very hot weather.
