A couple of rather quick-moving cold fronts in progressive northwest flow may bring some isolated corn earworm migration risks to at least portions of the corn-growing region in the next five days. The first front is currently crossing the central and northern portions of the corn-growing region, and may result in an isolated moth flight especially along and east of the I-55 corridor tonight into tomorrow morning, or from central/eastern Illinois east into Indiana, Ohio, southern lower Michigan, and also southern Ontario, Canada. The second front should cross the corn-growing region over the weekend and early next week, and initially brings a Low risk to fields mainly west of the Mississippi River and south of I-90 Saturday night into Sunday morning and then east of I-55, again, by Sunday night into Monday morning. Growers should continue to monitor traps and scout fields especially in fields and gardens where crops are at a susceptible stage to damage.
