Alert Details

An active weather pattern is in place across much of the central United States and it is expected to continue through early next week. Another low pressure system is predicted to roll out of the southwestern United States and into the Midwest late in the weekend and early next week. The predicted track of the low pressure and the presence of high pressure remaining over the southeastern United States should create a favorable corridor for south to southwest winds to originate in the southern Plains and mid-south region of the country where corn earworms are presently active. Only a Low corn earworm migration risk is being issued for Sunday night into Monday morning, however, due to corn crops running behind average and only a small percentage of emerged corn being present in the Midwest. The risk area is focused where crops are furthest along and/or where southerly winds are expected to be the strongest which stretches from far eastern Kansas through Missouri into southwest Illinois. While the potential for an isolated flight is there, risks are kept low given the time of the year as well.
