Corn earworm migration risks will continue in the forecast through mid-week as south to southwest flow persists ahead of a developing low pressure system in the Plains states. Low risks are in place tonight into tomorrow morning mainly along and south of I-80. To the south of this front, warm to hot and humid conditions along with southerly winds may lead to some isolated moth flights into some fields. The overall wind flow is not overly strong, thus, just Low risks are in place at this time. Late tomorrow night into Wednesday morning, however, stronger south to southwest winds are anticipated as a cold front begins pushing southeast across the northern and western corn-growing region. As a result, Moderate risks are in the forecast and are focused from far eastern Nebraska into Iowa, southern Minnesota, southwest Wisconsin, and northwest/western Illinois with Low risks to north of Minneapolis, Minnesota and east into Wisconsin, and mainly west of the I-69 corridor in central lower Michigan and northeast Indiana. No additional risks are in the forecast after midday Wednesday as northwest flow temporarily returns to the corn-growing region. Growers are encouraged to monitor traps and take appropriate action, if needed, as many crops are now in or entering critical growth stages.
