Quad Cities, IA/IL – Storms moving across eastern Iowa and western Illinois could drop over an inch of rain by late Tuesday night, bringing a risk of urban flooding and travel disruptions into Wednesday morning.
According to the National Weather Service in the Quad Cities, showers will increase in coverage Tuesday afternoon, with occasional heavy rainfall rates likely. Rainfall chances range from 60% to 90%, and some areas could see over 2 inches through Wednesday morning. While thunderstorm activity is expected, confidence remains low on whether any storms will reach severe levels.
Cities across the region — including Davenport, Rock Island, Moline, and Muscatine — should prepare for slick roads during the evening commute and potential localized flooding, especially in low-lying or poorly drained areas. Breezy conditions could accompany storms, with embedded gusty winds.
Residents are urged to stay weather-aware and delay non-essential travel during periods of heavy rain. Charge mobile devices in case of outages and avoid driving through flooded roadways.
While Monday will stay warm with smoky skies and highs in the upper 80s, conditions shift sharply Tuesday with widespread rain. Additional updates and advisories are possible as confidence grows in storm strength and timing.
