Dry and hot conditions will cover most of the primary U.S. and Canadian Prairie crop regions Tuesday. We'll see a few showers in northern Wisconsin, northern Michigan and south Texas. Heat advisories and warnings cover the entire western and most of the northern Corn Belt. This combination will further stress crops and livestock in this difficult late season. Hot and breezy conditions are also in store for the first day of the Farm Progress Show near Decatur, Ill.
