Des Moines, Iowa – Severe storms are expected to develop after sunset Sunday, with the first round bringing large hail and damaging winds to western Iowa before expanding statewide into Monday.
According to the National Weather Service in Des Moines, storms will intensify after dark Sunday, especially west of I-35, where isolated severe storms are possible through the overnight hours. The primary threats include large hail and strong wind gusts, with activity moving east into central Iowa by early Monday morning.
By Monday, the risk increases significantly across central and eastern Iowa, including Des Moines, Ames, Cedar Rapids, and Davenport. Multiple rounds of storms are expected, with the most intense activity likely during the afternoon and early evening hours. Damaging winds, large hail, and a few tornadoes are all possible, particularly along major corridors like I-80 and I-380 where travel could be impacted.
Drivers should prepare for sudden downpours, reduced visibility, and debris on roadways during peak travel times. Secure outdoor items and ensure mobile devices are charged ahead of the storms, especially before going to sleep Sunday night.
Storms may continue into Monday evening before gradually weakening, but additional alerts are likely as timing and severity become more certain across Iowa.
