Davenport, Iowa – Drivers across eastern Iowa and northern Illinois could face flooded roadways and strong crosswinds during the April 1–7 period as multiple storm systems move through the region, raising the risk of delays along I-80, I-88, and I-74.
According to the National Weather Service Climate Prediction Center, this region sits in one of the highest precipitation zones in the country, with up to an 80% probability of above-normal rainfall across eastern Iowa and much of Illinois. A slight risk of high winds also extends across both states, with stronger gust potential developing farther west but still impacting travel corridors here.
Rainfall totals between 2 and 4 inches are possible, especially in cities like Davenport, Rock Island, Peoria, and Chicago. Low-lying roads, underpasses, and poor drainage areas could see rapid water buildup, while rivers including the Mississippi may experience rising levels through the period. State transportation agencies including IDOT and Iowa DOT may issue alerts if standing water impacts key routes.
Wind gusts between 40 and 50 mph are possible at times, particularly across open stretches of highway. These gusts could create hazardous conditions for high-profile vehicles, especially on east-west routes like I-80.
Temperatures are expected to run above normal, keeping precipitation primarily rain and supporting repeated storm development.
This active pattern will persist through April 1–7, with additional advisories or localized flood warnings possible as conditions evolve.
