Quad Cities, Iowa/Illinois – Severe storms threaten communities across eastern Iowa and northwestern Illinois late Monday into early Tuesday, with damaging winds, large hail, and a tornado risk especially for Waterloo, Cedar Rapids, and the Quad Cities.
According to the National Weather Service Quad Cities office, isolated to scattered thunderstorms may develop Monday afternoon and evening, with a higher concentration of storms possible along a cold front Monday night. The most intense activity is expected between 8 p.m. and 2 a.m. Tuesday, and the threat level is highest for areas along and north of I-80—including Waterloo (level 4 risk), Cedar Rapids, and Dubuque. Damaging winds and large hail remain the primary concerns, but tornadoes cannot be ruled out.
Residents in Clinton, Burlington, and Galesburg should also prepare for severe weather and stay alert for warnings, especially overnight. Power outages, hazardous travel, and downed trees are possible. If you live in a manufactured home or an area prone to power loss, charge devices and identify your nearest safe place now. Have multiple ways to receive alerts—including NOAA weather radio and phone apps.
The threat is expected to taper off by early Tuesday morning, but additional advisories may be issued as confidence in storm development evolves. Stay weather-ready and monitor updates from local emergency agencies.
