Across the Corn Belt, thunderstorms pepper areas west of the Mississippi River. The rain is halting fieldwork but boosting soil moisture in previously dry areas of the western Corn Belt. On April 24, Nebraska led the Midwest with topsoil moisture rated 82% very short to short. Meanwhile, cool conditions linger across the northern and eastern Corn Belt, where planting has been delayed by cool soils and wet fields. Frost was noted this morning in parts of Michigan and Ohio.
