A strong cold front will push through the central and eastern corn-growing region over the next 24 hours. Ahead of this front, rather stout south winds are expected, and may lead to scattered black cutworm moth flights especially for areas in far eastern Illinois, Indiana, Ohio, and southern lower Michigan where a Moderate migration risk is in the forecast. Low risks extend from central Illinois as far east as Pennsylvania and north into central lower Michigan and southern Ontario, Canada. With north winds likely Wednesday into Thursday for most areas, little to no risk is predicted at that time, but Low risks then return to the forecast by Thursday and Friday nights ahead of the next weather system. This system looks weaker, but enough southerly winds in advance of it may lead to isolated moth flights initially west of I-35 in the Plains and nudging into western Iowa and Minnesota with the risk then spreading as far east as the I-69 corridor in Michigan and northeast Indiana by Friday night into Saturday.
