Alert Details

Broad northwest to southeast wind flow across the central and much of the eastern portion of the country is expected to greatly inhibit corn earworm migration in the next five days. The only opportunity for south to north flights in the next five days appears to be late Thursday night into Friday morning especially in the Plains and western corn-growing region as a cold front advances east from the Rocky Mountains. South to southwest winds are expected for a brief time period ahead of this front and may result in isolated moth flights to the north but mainly over shorter distances. A Low corn earworm migration risk is in place mainly across Kansas, Nebraska, southern South Dakota, southwest Minnesota, western Iowa, and far western Missouri during this time. Otherwise, no migration risk is predicted in the next five days.
