No risk of corn earworm migration is predicted until Saturday night when the next low pressure system advances into the Plains states. At that time, a warm front is expected to position itself from the central Plains through the corn-growing region. This front could be the focal point for not only showers and thunderstorms but also the area where corn earworm drop-out may occur but primarily on an isolated basis due to rather weak southerly winds. The risk area is initially in the Plains on Saturday night but does shift east into Iowa, Illinois, and Missouri in addition to the Plains states for Sunday night into Monday morning. Otherwise, northwesterly wind flow is expected to dominate the weather across the corn-growing region so no other risk area is in place at this time.
