Alert Details

The active weather pattern across the corn-growing region is expected to continue this week and beyond. As a result, multiple days of black cutworm migration risks are predicted with another potentially strong weather system late this week and next weekend resulting in elevated migration risks possible. For now, the first low pressure system and cold front should continue to push east through the corn-growing region today into tonight. Southwest winds are likely to continue to the east of the front with Low risks from roughly I-57 in eastern Illinois and points east into the western Appalachian Mountains and also north into lower Michigan. A brief break in the risks is then expected tomorrow night into Wednesday morning, but Low risks return from Kansas and Missouri north as far as central Minnesota and Wisconsin Wednesday night into Thursday morning, and then mainly across the Plains states Thursday night into Friday, and eventually as far east as the Great Lakes region and north into potentially North Dakota, northwest Minnesota, and portions of central Wisconsin by Friday night into Saturday. We do expect to upgrade the late-week risk level once system timing is more clear in the next 24-48 hours, so growers should continue to monitor forecasts as additional black cutworm moth flights look possible in the next week.
