Alert Details

A cold front will continue to push southeast through the corn-growing region today into tomorrow. Ahead of the front, however, south to southeast winds may lead to isolated corn earworm moth flights especially into the southern Great Lakes region and eastern corn-growing region tonight into tomorrow morning. The Low risk area is mainly east of I-55 in Illinois. Once this front moves through or stalls in the Ohio River valley this weekend, northwest flow should dominate the weather across much of the remainder of the corn-growing region so no insect migration risks are predicted through the weekend. Low risks return from central Missouri east into western Ohio and north into lower Michigan Monday night into Tuesday and then across the far eastern corn-growing region next Tuesday night into Wednesday morning as a low pressure system tracks through the heart of the corn-growing region. There is still some uncertainty with both the strength and placement of this system so only Low risks are in the forecast at this time.
