An active weather pattern is expected this week especially across the southeast half of the corn-growing region as a persistent southwest flow situation remains in place. With the insect source region expected to be located across the deep south and potentially as far north as into the mid-south and south to southwest winds blowing into a stagnant frontal boundary further north, black cutworm migration risks will be in the forecast for the next three days with a Moderate risk tomorrow night into Wednesday. Low risks are expected to focus from southeast Missouri into Illinois, Indiana, Ohio, and Kentucky tonight into tomorrow morning where these winds are most likely. By tomorrow night, however, a more favorable weather pattern is likely for migration especially across the southeast third of the corn-growing region, and a Moderate risk is in place from eastern Missouri into central Illinois, Indiana, and far western Ohio. Low risks extend from roughly I-35 east and as far north as into Wisconsin and lower Michigan during this time. Low risks continue in the forecast mainly east of I-35 Wednesday night into Thursday, but the best risk for migration this week will be tomorrow night into Wednesday. Growers should be advised that these moth flights may result in new generations next month once corn emerges so it is important to monitor traps during this active weather pattern.
