An active weather pattern featuring persistent areas of low pressure systems and a cold front in the Plains and high pressure across the southeastern United States should lead to rather persistent south to southwest winds across a large portion of the corn-growing region for the next several days. Low migration risks are predicted on a nightly basis from tonight into Saturday morning, so some isolated moth flights are possible. The risk area tonight into tomorrow morning mainly south of US 20 and west of the Mississippi River, or from Nebraska and Iowa south into Kansas into Missouri. The risk area shifts east between I-35 to I-75 tomorrow night into Thursday morning, and then refocuses west as a new low pressure develops later this week. The risk area initially is mainly in the Plains northeast into the southwestern Great Lakes region, and then shifts mainly east of I-35 from Iowa and Minnesota east into the southern Great Lakes region into the eastern Midwest by late week and early into the weekend. Growers should be advised that there is no threat to crops at this point, but these early flights may result in additional generations later this summer that could harm crops so intense moth flights should be noted.
