A cold front will work its way from northwest to southeast across the corn-growing region between now and into early next week. South to southwest winds will persist east of the front, and may lead to some isolated corn earworm moth flights into the remaining processing and fresh market fields especially in the northern portion of the corn-growing region. Low risks are predicted tonight into tomorrow mainly west of Lake Michigan, with the risk then spreading east from southeast Kansas, Missouri, southern Illinois, and western Kentucky as far north as Wisconsin and southwest lower Michigan. As the cold front moves further east, any remaining migration risks look to focus mainly in the southern Great Lakes and eastern corn-growing region by later Sunday into Monday. Northwest flow locks back in next week with cooler temperatures and less humidity, so little to no migration risk is predicted after Monday.
