A cold front is likely to push southeast through the corn-growing region over the next 24 hours. As it does so, showers and thunderstorms are likely to develop along the front, right along the I-80 corridor, from Iowa and points east into Illinois. South to southwest winds are likely east of the rainfall and front but are not expected to be overly strong. Given these factors, Low corn earworm migration risks are predicted tonight into tomorrow morning from eastern Kansas and Missouri northeast into southeastern Iowa, Illinois, Indiana, Ohio, and southern lower Michigan. We did reduce the risk further east into Ontario, Canada due to continued high pressure influence further northeast across southeast Canada and the northeast United States. No additional risks are in the forecast through early next week.
