Peoria, Illinois – A fast-moving thunderstorm complex is barreling toward central and northern Illinois early Tuesday, bringing the potential for damaging wind gusts north of Interstate 74 before sunrise.
According to the National Weather Service in Lincoln, the storm system is expected to weaken as it moves southeast from Iowa, but could still deliver wind gusts up to 60 mph, heavy rainfall, and frequent lightning—especially in areas north of I-74. The most intense weather is forecast to hit counties west of the Illinois River around 4 a.m., reaching the I-55 corridor closer to 5 a.m.
Cities including Peoria, Galesburg, Macomb, and the Quad Cities are under the highest threat window. Commuters and early risers should be alert for sudden power outages, hazardous road conditions, and possible tree or property damage. Major highways such as I-74 and I-55 may see reduced visibility and pooling water, increasing the risk for hydroplaning.
Residents are urged to seek shelter indoors as storms approach and ensure mobile devices are charged in case of outages. The National Weather Service also recommends having a reliable way to receive warnings overnight, as severe conditions can develop quickly.
This line of storms marks one of the season’s more intense July events in central Illinois, though a gradual clearing is expected later Tuesday morning. Additional weather advisories may follow as the system tracks east.
