Alert Details

A cold front will be pushing southeast through the central and eastern corn-growing region over the next 24-36 hours. This front divides very warm to hot conditions, along with south to southwest winds, to its east in contrast to much cooler conditions to its north with west to northwest winds. A few corn earworms may fly north on the southwest winds ahead of the front later today and overnight tonight especially across portions of northern Missouri, eastern Iowa, far southern Wisconsin, northern and central Illinois, northern Indiana, northwest Ohio, and southern lower Michigan. Processing and fresh market growers in these areas should continue trapping and scouting efforts until harvest. Otherwise, much cooler conditions are expected for the rest of the week and into the weekend on northern winds so little to no additional migration risk is predicted after midday Wednesday.
