Alert Details

An active weather pattern is anticipated through the middle portion of this week, and the possibility of black cutworm flights exists especially over the eastern portion of the corn-growing region. Moderate risks are in place tonight from far southeast Missouri into southeast Illinois, Indiana, western Ohio, and western Kentucky as south to southwest winds should maximize over this area. A few moth flights may also be observed as far north as southern Wisconsin and southern lower Michigan, as well. Low risks are in the forecast tomorrow night into Wednesday morning from eastern Kansas and Iowa east into the eastern corn-growing region as a new low pressure area organizes over the southwestern Plains states. Moderate risks are back in the forecast by Wednesday night into Thursday as this new weather system continues to deepen over the upper Midwest and a cold front pushes through the entire corn-growing region. The Moderate risk area is mainly east of I-57 in eastern Illinois and into far southern lower Michigan, Indiana, western Ohio, and Kentucky. No additional migration risks are predicted after Thursday morning. Growers located especially east of the Mississippi River should monitor traps very closely in the next week for more intense moth flights, especially in areas where corn planting is ongoing or only recently began to occur.
