Corn earworm migration risks remain in the Low category for the next five days with primary risk areas focused in the western and central corn-growing region. After high pressure currently in the Plains states moves into the eastern corn-growing region and eventually southeast United States, southerly winds will initially return to the Plains states but will eventually spread east into the Midwest. Southerly wind speeds, however, are not expected to be particularly strong in the next five days so only Low migration risks are predicted at this time. Risks are initially in place for Wednesday night into Thursday morning mainly west of a Springfield, Missouri to Eau Claire, Wisconsin line and south of US 12 in South Dakota and Minnesota. The risk area expands east to Lake Michigan and into Illinois for Thursday night into Friday but then re-focuses across the Plains and western corn-growing region as new low pressure develops in the central Plains region. The risk area returns east into Wisconsin and Illinois by Saturday night and Sunday morning as southerly winds push back east as low pressure deepens.
