Across the Corn Belt, thunderstorms are affecting a few Midwestern locations. However, most of the region remains dry, continuing a general pattern that has lasted about 2 weeks. In addition, very hot weather prevails west of the Mississippi River, where Wednesday’s high temperatures should generally range from 95 to 105°F. Corn and soybeans in drier areas of the upper Midwest have been lacking in soil moisture and rainfall during the critical reproductive stage of development.
