According to the National Weather Service in the Quad Cities, a marginal risk (level 1 of 5) for severe weather exists for the area, with a 10–20% chance of thunderstorms late this evening into tonight. Storms are most likely northwest of the Quad Cities, including parts of Cedar Rapids, Dubuque, and stretching into Illinois border communities.
