Low corn earworm migration risks will continue in the forecast tonight into tomorrow morning mainly east of a line from near Lincoln, Nebraska to Minneapolis, Minnesota to the I-69 corridor in central lower Michigan and northeast Indiana. A cold front is expected to push southeast through much of the corn-growing region over the next 24-48 hours, and will eventually switch winds around from the south to the west and northwest. The migration risk will end by midday Tuesday as winds will become unfavorable for migration and also as cooler weather sets back in, so no additional risks are predicted after Tuesday morning.
