Alert Details

An active southwesterly flow weather pattern is predicted to return to a large portion of the corn-growing region later this week and especially into next weekend. As a result, Low corn earworm migration probabilities are also back into the picture especially in the Plains by tomorrow night into Thursday morning and then further north and east into the upper Midwest, central and eastern corn-growing region, and Great Lakes states by the weekend as southerly winds expand eastward. Showers and thunderstorms are also likely to occur during this time and may serve as insect drop-out regions especially where southerly winds first encounter precipitation areas. Given the time distance, only Low risks are currently in place but there is a chance that increased risks may be needed especially by this weekend and early next week when a cold front pushes into the corn-growing region. Continue to monitor subsequent forecasts for the latest information and also continue to check your traps for a better indication of local moth pressure in your specific area.
