Alert Details

A rather active weather pattern typical for mid-late September is predicted to continue into next week. The result will be periodic risks for mainly isolated corn earworm migration especially across the northern portions of the corn-growing region where there may still be some fresh market and processing fields still at risk. A cold front will sweep through the central and eastern corn-growing region in the next few days. As it does so, a Low migration risk will exist tonight mainly east of a Kansas City, Missouri to Wausau, Wisconsin line and east of US 127 in Michigan and I-69 in Indiana tomorrow night into Saturday morning. Low risks return to the Plains and eventually across the upper Midwest by late in the weekend and early next week as the next cold front begins to move into the central United States. Southerly winds in advance of the front may pose an isolated migration risk at that time.
