Across the Corn Belt, a storm system traversing the middle Mississippi Valley is resulting in a variety of weather hazards. A band of snow expanding northeastward from the western Corn Belt is leading to travel difficulties and increased livestock stress. Early Thursday, some of the most significant snow is falling from southeastern Nebraska into Iowa. Meanwhile, heavy showers and locally severe thunderstorms are affecting the lower Ohio Valley. Flash flooding is a concern in areas where the heaviest rain is falling.
