Alert Details

Corn earworm migration probabilities are predicted to remain limited the next five days as a predominantly zonal or northwesterly flow pattern envelops much of the corn-growing region. After a night of no risk overnight tonight into tomorrow morning, Low risks return to the Plains and western Midwest as southerly winds increase to the east of the next cold front. The primary risk lies across portions of Kansas, Nebraska, and Iowa, but also includes sections of South Dakota, Minnesota, and Missouri. The risk becomes suppressed to south of US 30/I-80 and also primarily across the southwestern corn-growing region by Wednesday and Thursday nights as a cold front pushes slowly south through the corn-growing region. No risk is predicted thereafter as southerly winds subside.
