Des Moines, Iowa – Drivers across Iowa could encounter water-covered roads and strong crosswinds during the April 1–7 period as repeated storm systems track through the region, increasing the risk of travel disruptions on I-35, I-80, and I-29.
According to the National Weather Service Climate Prediction Center, Iowa sits in a corridor with up to an 80% probability of above-normal precipitation, one of the highest signals in the country during this stretch. A slight risk of high winds also extends across the state, with stronger wind zones developing just to the west across Nebraska and the Plains.
Rainfall totals may exceed 2 inches in parts of central and eastern Iowa, including Des Moines, Cedar Rapids, and Davenport. Low-lying roads, intersections, and rural areas with poor drainage could see temporary flooding. The Iowa Department of Transportation may issue alerts if standing water begins to impact key highways.
Wind gusts between 40 and 45 mph could develop at times, especially across open areas of western and northern Iowa. These conditions may create difficult travel for semis and high-profile vehicles, particularly along north-south routes like I-35.
Temperatures are expected to run above normal, keeping precipitation primarily rain and supporting an active storm pattern. Cities like Ames and Iowa City will see mild conditions, but with an increased chance of repeated rainfall.
This unsettled pattern will persist through April 1–7, with additional advisories or localized warnings possible as each system moves through the state.
