Alert Details

An active corn-growing region weather pattern is expected over the next 5-7 days which may lead to at least isolated corn earworm moth migration events. The first potential risk comes overnight tonight into tomorrow as a cold front pushes east across the Great Lakes and eastern corn-growing region. Low risks are predicted primarily in weaker south to southwest wind flow east of this front, mainly along and east of the I-57 corridor in eastern Illinois. Low risks then focus back west of I-35 tomorrow night into Friday as the next weather system develops in the northern Plains and southern Canada. By the weekend and into early next week, Low risks envelop a large portion of the corn-growing region, and it is entirely possible that a risk upgrade in certain areas will occur in the next few days once forecast confidence increases.
