A strong low pressure system will continue to develop and move slowly east across portions of the western and central corn-growing region through the weekend. Very gusty south to southwest winds are expected to the east and southeast of the low pressure center, especially from the mid-south region northeast into the central and eastern corn-growing region. For this reason, Moderate black cutworm migration risks are in the forecast tonight into tomorrow morning over a pretty large area extending from the Illinois River valley in western/central Illinois all the way east into Ohio and north into southern lower Michigan and far southwest Ontario, Canada. Low risks extend from roughly the I-35 corridor to along/south of I-90/I-94 west of Lake Michigan and into southern lower Michigan as well as into portions of southwest and southern Ontario, Canada and Pennsylvania. No additional risks are predicted in the latter half of the weekend and into early next week as northwest flow once again returns and dominates the weather pattern.
