A cold front will be pushing southeast through the corn-growing region over the next 24-48 hours. Ahead of the front, south to southwest winds along with at least scattered precipitation areas may lead to some corn earworm moth flights. Moderate migration risks are predicted tonight into tomorrow morning from eastern Iowa into northern and central Illinois, southeast Wisconsin, northern Indiana, and southwest lower Michigan. Low risks extend to the I-75 corridor in eastern Michigan and western Ohio. Moderate risks are then in the forecast tomorrow night into Sunday morning across Indiana, Ohio, lower Michigan, southern Ontario, Canada, western New York, and Pennsylvania as the front continues to move to the east. A more favorable source region in the mid-south may lead to enhanced flights into this area. Looking ahead to next week, yet another weather system should develop east of the Rocky Mountains and then move east through the corn-growing region. Low migration risks are already in place west of Lake Michigan by Monday night into Tuesday, and then as far east as the Great Lakes and eastern corn-growing region by mid-week. Increased migration risks may accompany this system, as well, so growers are urged to continue to monitor traps and scout fields especially if crops are at a susceptible stage to damage.
