Across the Corn Belt, a broken line of showers extends southwestward from the upper Great Lakes region. Any rain in the western Corn Belt is too late to benefit maturing corn and soybeans. Meanwhile, warm, dry weather across the southern and eastern Corn Belt is helping to push summer crops toward maturity. On September 11, only 16% of the corn in Illinois was fully mature, compared to the 5-year average of 36%.
On the Plains, hot weather persists across the southern half of the region, where Friday’s high temperatures will generally range from 90 to 95°F.
