Alert Details

Low corn earworm migration risks are in place tonight into Wednesday morning mainly south of a line from Dodge City, Kansas to Lincoln, Nebraska, Rochester, Minnesota, and Green Bay, Wisconsin. A cold front will push southeast through the upper Midwest and Great Lakes region into the eastern Midwest and Ohio River valley by tomorrow. Showers and thunderstorms will be numerous along/southeast of the front along with somewhat weak southwest winds. The lack of stronger winds and also more widespread precipitation precludes a higher risk at this time. Low migration risks in a continued weak southerly flow ahead of the next weather system are predicted across the Plains states Thursday night into Friday and then across much of the corn-growing region this weekend.
