Alert Details

Black cutworm migration risks will continue to be elevated for the next couple nights as rather strong south to southwest flow to the southeast of a cold front continues. Moderate risks are in the forecast tonight into tomorrow morning from northeast Kansas northeast into Iowa, far southeast Minnesota, Missouri, Illinois, Wisconsin, southern lower Michigan, and into Indiana and northwest Ohio, as well. Low risks extend just north and northwest of the Moderate risk area and also as far east as southern Ontario, Canada and near the Ohio/Pennsylvania border. Tomorrow night, the cold front is expected to make some southeastward progress, and the strongest corridor of southwest winds should focus mainly east of the Illinois River into the southern Great Lakes region where Moderate migration risks continue. Low risks extend east into Pennsylvania and southern Ontario, Canada. Low risks remain in the forecast Thursday night into Friday morning mainly east of a line from near Columbia, Missouri to Chicago, Illinois, but no additional risks are predicted thereafter as a cooler, drier, and northwest-flow dominated weather pattern once again take hold over much of the corn-growing region by this weekend.
