Alert Details

Low black cutworm migration risks are in the forecast tonight into tomorrow morning as a cold front works its way east across the corn-growing region. The low risk area mainly focuses from far northeast Kansas into eastern Iowa, southeast Minnesota, Wisconsin, Illinois, Missouri, and far eastern Indiana. Low risks follow the front east tomorrow night into Thursday morning, with fields from I-57 in eastern Illinois and points east into Indiana, Ohio, and southern lower Michigan at risk of seeing some isolated moth flights. By late week into next weekend, a stronger and potentially slower moving storm system will keep nightly black cutworm migration risks in the forecast, with Low risks initially beginning in the Plains and western corn-growing region Wednesday night into Thursday spreading east into the southern Great Lakes and eastern corn-growing region by the weekend. An area of Moderate risk across northeast Iowa, northern Illinois, far southeast Minnesota, and Wisconsin has been introduced into the forecast for the Friday night into Saturday morning time frame when a combination of gusty south winds to the south of a warm front and precipitation to the north may lead to an area of enhanced insect drop-out especially to the west of Lake Michigan.
