An active weather pattern especially from I-80 south is expected the next three days. As a result, Low corn earworm migration risks are predicted especially in the southern Midwest, Ohio River valley, and also into the eastern Corn Belt. As a cold front sags south later today and into tonight, southwest winds originating in northern Texas and southern Oklahoma may pose an isolated migration risk especially for central and southern Missouri and north of the Ohio River valley where scattered precipitation areas may serve as insect drop zones. By later Tuesday into Wednesday, the next low pressure system emerges in the Plains and the migration risk area shifts west from the eastern Plains into the Mississippi River valley. Some flights may occur as far north as Iowa and northwest Illinois by Wednesday morning. The risk area shifts east into the eastern Corn Belt and Ohio River valley by Wednesday night and Thursday morning as low pressure and its attendant cold front advance to the east. No risk is predicted after Thursday morning.
