Alert Details

A continued active weather pattern is predicted for the next week across a large portion of the corn-growing region. Black cutworm migration risks will follow suit, with enhanced risks once again in the forecast by the middle of the week as a strong cold front works its way across the area. Low risks are in the forecast tonight into tomorrow morning from southeast Nebraska and Missouri northeast into Iowa, Minnesota, Wisconsin, and Illinois as south to southwest winds increase to the east of a cold front trailing to the south of low pressure across the northern Plains. Moderate risks are in the forecast Tuesday night into Wednesday morning across much of Illinois east into Indiana and southwest lower Michigan as the black cutworm source region is expected to be in a more favorable location once again across the mid-south region of the country and as south to southwest winds persist to the east of the cold front. Moderate risks remain in the forecast Wednesday night into Thursday morning especially from central and eastern Indiana east into Ohio, southeast lower Michigan, and also across much of southern Ontario, Canada as the front moves east. Many black cutworm flights have been observed across the corn-growing region in the last few weeks, and growers all across the corn-growing region should continue to monitor traps closely especially with planting underway and emergence to follow, if not already, in some areas.
