Davenport, Iowa – Scattered thunderstorms are sweeping across the Iowa-Illinois border this morning, bringing lightning, small hail, and slick roads to early commuters through 9 a.m. Tuesday. Drivers from Waterloo to Rockford should be alert for wet pavement and brief downpours during peak travel hours.
According to the National Weather Service Quad Cities, showers are moving east at 40 mph and are expected to impact areas including Cedar Rapids, Iowa City, and the Quad Cities region. Stronger cells may produce small, non-damaging hail and frequent lightning, especially along I-80 and U.S. 30.
A second wave of storms is likely later this afternoon into the evening, with isolated severe threats. While the chance of widespread severe weather is low, the strongest storms may bring large hail and gusty winds, particularly in communities like Galesburg and Sterling. Any heavy rain is expected to be localized, mainly where storms repeat over the same area.
Residents are urged to stay weather-aware and have multiple ways to receive alerts. Marginal severe risk continues through tonight, with more scattered storms possible into midweek.
