Across the Corn Belt, showers and thunderstorms are affecting the Great Lakes region and areas west of the Mississippi River. Early Thursday, some of the heaviest rain is falling in Iowa and northern Missouri. In upper Midwestern areas where snowmelt flooding is occurring, rain is aggravating the situation. Moderate to major flooding is being observed at more than three dozen river gauges, including most locations on the Mississippi River from La Crosse, Wisconsin, northward.
On the Plains, cool weather trails a cold front’s passage.
