Davenport, Iowa – Storm chances creep back into eastern Iowa and northwest Illinois tonight as a weak system tracks near Highway 20. The National Weather Service warns of scattered thunderstorms and lightning risk mainly this evening and overnight. Area rivers could also see flooding into early next week, prompting drivers and boaters to use extra caution.
According to the National Weather Service office in the Quad Cities, thunderstorms remain a low threat through tonight but could bring dangerous lightning north of Interstate 80. Flood watches remain in place for several counties along the Mississippi River, including Scott, Rock Island, and Muscatine, where high water levels may linger into Labor Day weekend.
Travelers should avoid flooded roadways and plan alternate routes. With increased holiday travel expected, officials urge drivers to stay alert for sudden water over highways and to never attempt to cross submerged roads.
Beyond tonight, drier conditions return. Thursday brings sunshine and highs in the low 80s, followed by a stretch of calm, warm weather through Labor Day. Weekend highs will climb into the upper 70s and near 80, with mostly clear skies dominating the forecast.
While storm threats fade after tonight, river flooding could continue to impact communities along the Mississippi into next week. Emergency managers advise residents to monitor river forecasts closely.
