Alert Details

Increasing black cutworm migration risks are in the forecast late this week into the first part of the weekend as a strong low pressure system moves through the heart of the corn-growing region. Initially, Low risks are predicted on Thursday night into Friday morning as southerly winds increase to the east of the low pressure. The Low risk area extends from northeast Kansas into eastern Nebraska, southeast South Dakota, portions of central and southern Minnesota and Wisconsin, Iowa, Illinois, Missouri, Indiana, far western Ohio, and southwest lower Michigan. By Friday night into Saturday morning, as the low pressure continues to deepen in the east central Plains states, southerly winds are expected to become even stronger and originate in a more favorable black cutworm source region. For this reason, Moderate risks are in the forecast especially along and east of the Illinois River from central Illinois into Indiana, Ohio, southern lower Michigan, and also into southwest Ontario, Canada. A cold front is likely to move east through the corn-growing region during the weekend and will end any further migration threats.
