Alert Details

Corn earworm migration risks are being kept in the Low category for this forecast cycle as an active but very progressive weather pattern may limit larger scale moth flights. In addition, corn crops are not at a susceptible stage to damage at this point, but host plants could serve as a location for future generations to develop. No risk is predicted overnight tonight into Thursday morning, but Low risks return to the Plains states by Thursday night into Friday as the next weather system develops in the Rockies and moves into the Plains. Low risks continue primarily from Kansas and Missouri to as far north as Minnesota and Wisconsin Friday night into Saturday as south to southwest winds coincide with rainfall during that time. Fields as far east as Michigan and Indiana may be impacted by isolated moth flights Saturday night into Sunday before the risk tails off thereafter due to low pressure moving out of the region.
