Des Moines, IA – Central Iowa is bracing for a stormy Sunday, with strong thunderstorms and heavy rain expected to push through by afternoon and continue into the evening. Some areas could see rainfall totals exceeding 2 inches, raising the risk of localized flooding, especially in low-lying neighborhoods and along smaller creeks.

According to the National Weather Service, rain chances jump to 70% on Sunday, with storms most likely between 1 p.m. and midnight. East to southeast winds will shift south later in the day, with gusts topping 25 mph in open areas. The heaviest downpours could affect travel along I-35 and I-80 during the evening commute, and lightning risk will be high for outdoor activities.

By Monday, skies begin to clear, with only a slight storm chance early in the day before drier conditions take hold. The rest of the week turns warmer and sunnier, offering a welcome break from the wet weather.

Residents should avoid driving through flooded streets and have alternate indoor plans for Sunday. Warnings could be extended if storms slow or intensify.
