Quad Cities, Iowa/Illinois – A fast-moving round of thunderstorms threatens the Quad Cities region with damaging winds, heavy rain, and frequent lightning between 6 and 10 p.m. tonight, putting outdoor activities and evening travel at risk.
According to the National Weather Service Quad Cities, a Marginal Risk (Level 1 of 5) for severe weather covers areas near I-80 and northward, including Cedar Rapids, Iowa City, and Dubuque. Isolated storms could produce wind gusts over 50 mph, minor flooding from heavy downpours, and a low risk of a brief tornado, mainly north of Highway 30.
Frequent lightning and sudden downpours may disrupt commutes, outdoor sports, and public events. Residents should plan to move indoors at the first sign of thunder and monitor alerts from multiple sources, especially in vulnerable areas along I-80, Quad Cities, and northwest Illinois.
Isolated power outages are possible if storms intensify. Stay prepared by charging devices, securing outdoor items, and avoiding low-lying roads prone to flash flooding. Even brief severe storms can create rapid hazards and travel disruptions.
Showers and storms may linger overnight, with another round of dangerous heat and storm chances returning midweek. Further advisories are possible as weather threats continue.
