Across the Corn Belt, showers in the vicinity of a cold front stretch from the Great Lakes region into the mid-Mississippi Valley. The rain is temporarily slowing fieldwork but promoting corn and soybean emergence and early-season growth. By May 23, nearly two-thirds (64%) of the U.S. corn and 41% of the soybeans had emerged. Warm weather prevails across the Ohio Valley in advance of the cold front, while cool air is overspreading the upper Midwest.
