A low pressure system and attendant cold front will move through the corn-growing region by late week and into next weekend. A period of southerly winds is likely just east of the front as it moves to the east. At the moment, however, the rather short duration of south to southwest winds is limiting the overall corn earworm migration risk but we still expect that there could be some isolated more intense flights mainly across the Plains into the western corn-growing region west of US 65 tonight into tomorrow. Tomorrow night into Thursday any flights would occur east of a line from near Wichita, Kansas to Minneapolis, Minnesota and mainly west of Lake Michigan, and finally Thursday night into Friday the primary corridor is between I-55 and I-75 from the mid-Mississippi River Valley northeast into the southern Great Lakes area. Growers should monitor traps and scout fields as some new moth flights may occur in the next week, and we are still considering risk upgrades should winds look to become stronger and/or in a more focused corridor.
