Alert Details

Low black cutworm migration risks are in the forecast tonight into tomorrow morning from northeast Kansas, eastern Nebraska, and southeast South Dakota all the way east into southern lower Michigan and Ohio as a strong low pressure system develops across the central Plains states. Southerly winds will increase today especially east of the low pressure system, and at least isolated moth flights will be possible as far north as the I-90 corridor west of the Mississippi River and south of the I-94 corridor in Wisconsin and Michigan tonight into tomorrow morning. As the low pressure system continues to churn and deepen across the western corn-growing region tomorrow, southerly winds will become slightly southwesterly and increase further. As a result, Moderate black cutworm migration risks are in the forecast especially from along and east of the Illinois River as far east as Ohio and north into southern lower Michigan and far southwest Ontario, Canada. Low risks extend from east of I-35 into Pennsylvania and Ontario, Canada. Once this system moves through, no additional risks are predicted for the rest of the weekend into early next week.
