A corridor of southerly winds is likely to develop mid-late week east of a low pressure system and associated cold front developing in the Plains states. Low corn earworm migration risks are in the forecast in this southerly wind corridor tomorrow night into Thursday across the Plains states and western corn-growing region, mainly to the west of the I-35 corridor from northern Kansas, northwest Missouri, Nebraska, western Iowa, South Dakota, southern North Dakota, and Minnesota. The Low risk area shifts east Thursday night into Friday as a cold front begins moving southeast through the corn-growing region. Fields as far east as Lake Michigan and into the I-55 corridor in Illinois are at risk. Little to no risk is predicted thereafter as northwest flow dominates the weather pattern, but growers with crops still at susceptible stages to damage, especially processing and fresh market growers in the northern corn-growing region, should continue to monitor traps and scout fields until the crops are no longer at risk or harvest occurs.
