Davenport, Iowa – Severe storms could rapidly intensify by mid-afternoon Thursday, bringing the threat of large hail, damaging winds, and isolated tornadoes across eastern Iowa and western Illinois.
According to the National Weather Service in the Quad Cities, storms are expected to develop between 3 p.m. and 11 p.m. Thursday, with intensity increasing into the evening hours as storms organize into stronger lines. The primary hazards include hail up to the size of golf balls and wind gusts strong enough to cause tree damage and power outages.
Cities along the Mississippi River, including Davenport, Bettendorf, Rock Island, and Moline, sit in a level 2 risk zone, while areas farther south and east toward Burlington, Macomb, and Peoria face a higher level 3 risk where more widespread severe storms are possible.
Storms that form early in the afternoon may remain isolated but capable of producing large hail and a brief tornado. As the evening progresses, the threat shifts toward stronger winds as storms merge and accelerate eastward.
Residents should secure outdoor items, review shelter plans, and enable emergency alerts ahead of the evening hours. Travel along I-74, I-80, and Highway 61 could become hazardous with sudden downpours and reduced visibility.
Storms are expected to weaken late Thursday night, but additional watches or warnings may be issued as conditions evolve.
