Chicago, Illinois – Drivers across the Midwest could face water-covered roads and reduced visibility during the April 1–7 period as repeated rounds of rain combine with unseasonably warm temperatures, increasing the risk of travel disruptions along major corridors including I-90, I-94, I-80, and I-70.
According to the National Weather Service Climate Prediction Center, the Midwest sits in one of the most active precipitation zones in the country, with up to an 80% probability of above-normal rainfall across states including Illinois, Iowa, Missouri, Indiana, and Wisconsin. Multiple storm systems are expected to move through the region, producing steady rain and periodic heavier downpours.
Rainfall totals between 2 and 4 inches are possible in cities such as Chicago, Des Moines, St. Louis, Indianapolis, and Milwaukee. Low-lying roads, underpasses, and poor drainage areas could see rapid water accumulation during heavier rainfall. Rivers and tributaries throughout the Mississippi and Ohio Valley basins may also rise steadily through the period.
Temperatures are expected to trend above normal, with warm and humid air helping fuel a moisture-rich environment that enhances rainfall efficiency. Overnight temperatures will remain mild, limiting cooling and supporting repeated storm development.
Rain will occur in waves, with heavier bursts capable of slowing travel during peak commute hours and reducing visibility on key interstates.
This wet and warm pattern will persist through April 1–7, with additional advisories or localized flood warnings possible as conditions evolve across the Midwest.
