Alert Details

A couple of weather systems over the next five days will provide at least some opportunity for black cutworm migration into a portion of the corn-growing region. The first chance comes overnight tonight into tomorrow morning in a somewhat narrow corridor from far eastern Kansas and Missouri into central/eastern Iowa, far southeast Minnesota, Wisconsin, and Illinois as a cold front pushes east through this region. South to southeast winds may allow for a few isolated moth flights into this region. A break is then expected into the weekend, but Low risks then return to a pretty large portion of the corn-growing region as southerly to southwesterly flow becomes dominant early next week. Low risks are found from Kansas and Missouri as far northeast as eastern South Dakota, Minnesota, Wisconsin, and into southwest lower Michigan and Indiana both Sunday and Monday nights ahead of the next potentially stronger weather system at that time.
