Alert Details

Elevated black cutworm migration risks will continue in the forecast for the next two nights as a rather potent cold front moves through much of the corn-growing region. South to southwest winds to the east of the front with high pressure located in a very favorable location across the southeastern United States will lead to the potential for scattered moth flights into the central and eastern corn-growing region. Moderate risks are predicted tonight into tomorrow morning for far eastern Nebraska, northern Missouri, Iowa, southeast Minnesota, Wisconsin, and into northern and central Illinois. Low risks extend east into western Ohio and much of southern lower Michigan. Moderate risks then shift east with the cold front tomorrow night into Sunday morning, and are focused mainly east of I-55 in Illinois, or including eastern Illinois, Indiana, Ohio, southern lower Michigan, and southwest Ontario, Canada. Low risks are found as far east as the Appalachian Mountains. Once this cold front is through the corn-growing region, a break in the risks is expected for early next week but another weather system brings an introductory migration risk back into the picture by Tuesday night into Wednesday, and mainly across eastern Illinois into Indiana, Ohio, and southern lower Michigan.
