Alert Details

A Low corn earworm migration risk is predicted later this evening into Saturday morning from Iowa and Missouri northeast through southern Wisconsin, Illinois, Indiana, Ohio, Michigan, and southwest Ontario as a cold front pushes southeast through the Great Lakes and Midwest. Southwest winds will persist to the south of the boundary but are expected to be much weaker in comparison to the past few nights so only Low risks are predicted at this time.

No migration risks are predicted after midday Saturday as high pressure builds into the Plains and Midwest. Also, a tropical depression in the Gulf of Mexico is expected to result in widespread northeast winds to its north and northwest side through the middle of next week. These two features will not allow southerly winds to become reestablished across the corn-growing region so no migration risk is predicted.
