Alert Details

Corn earworm migration risks do not return to the forecast until Friday night into Saturday morning as either calm or an unfavorable, northerly wind direction will not support migration risks until that time. By late week, a low pressure system is predicted to develop in the far northern Plains or southern Canada. Southerly winds will return to the Plains states initially, and Low risks are predicted Friday night mainly along and west of I-35. By Saturday night into Sunday, the Low risk area is expanded east as far as the I-69 corridor in lower Michigan and northeast Indiana and points west as high pressure drifts slowly to the east, allowing southerly winds to envelop the central and portions of the eastern corn-growing region. Growers with crops at susceptible stages should continue to monitor traps and scout fields despite the lack of risk at this time.
