Alert Details

Low pressure will continue to develop in the western Plains states today. Meanwhile, a frontal boundary should push southeast into the Ohio River valley, resulting in additional showers/storms in that area later today as well. Southerly winds across the southern into central Plains states may result in an isolated black cutworm moth flight especially into eastern Kansas overnight tonight. An additional Low risk area exists across the southern corn-growing region from southern Missouri east northeast into the Ohio River valley. By tomorrow and tomorrow night, low pressure should move into the upper Midwest so southerly winds will have an opportunity to increase and expand north ahead of a trailing cold front. A Moderate black cutworm migration risk is predicted from far southeast Missouri into eastern Illinois, Indiana, southern lower Michigan, western Ohio, and northern Kentucky with Low risks from Missouri, Illinois, and southeast Wisconsin east into southwest Ontario, Canada and Ohio. No additional risks are predicted after midday Thursday as northwest flow locks in into early next week. Growers especially across the eastern corn-growing region should monitor for new black cutworm flights especially given that this area is running behind on corn planting progress. Flights that occur now could affect later emerging fields late this month and into June.
