Alert Details

Remnants of Tropical Storm Bill will continue to move through the mid-south and southern Midwest during the next couple of days. Some weak southerly wind flow, originating from active source regions not far away in the mid-south and Mississippi delta region may pose a short distance corn earworm migration risk into southeast Missouri, southern Illinois, southwest Indiana, and western Kentucky tonight into tomorrow morning. Once Bill moves out, attention then shifts to the next cold front organizing in the Plains states. This front will initially bring a Low migration risk to the Plains and western Midwest by Friday night into Saturday morning. As the front pushes southeast over the weekend and into next week, it is expected to stall out or vacillate somewhere between I-90 and I-70, so isolated corn earworm migration risks will remain in the forecast mainly across the southern and central corn-growing region through the extended period. Growers should be on the alert for isolated moth arrival during this time.
