Low pressure is expected to develop across the High Plains over the next 24 hours, and as it does so, southerly winds will increase to its east. Light winds and cool weather should limit any black cutworm migration risk across eastern corn-growing region fields for the time being, but Low migration risks are predicted tonight into tomorrow mainly west of Lake Michigan and into portions of Illinois. Low risks then expand east tomorrow night into Thursday as a cold front begins moving east. Fields from near the I-35 corridor from eastern Kansas northeast into southeast Minnesota and as far east as southern lower Michigan and into western Ohio and Kentucky may see some moth flights. Little to no risk is predicted thereafter as the cold front is expected to move east, and northwest flow locks in for the weekend and likely into next week, as well.
