An active weather pattern is predicted especially across the southeast half or so of the corn-growing region mid-late week and into the weekend. Low pressure is expected to develop in the Plains and move northeast into the Great Lakes region. South to southwest winds east of a trailing cold front south of the low may result in some isolated corn earworm moth flights into areas especially east of the Mississippi River but there could be some moths that make it into Kansas, Missouri, and portions of Iowa especially Thursday night into Friday. The primary focus will be across eastern Illinois into Indiana, Ohio, Kentucky, lower Michigan, and even into southern Ontario, Canada Friday night into Saturday. Corn earworm moth populations in the source region (mid-south and lower Mississippi River valley) are not particularly high and corn is an attractive host in that region given crop stage so only isolated flights are expected further north into the main corn-growing region. Main concern at this point is with fresh market and vegetable hosts as most field corn is not at a critical stage of growth where damage would occur right now except in far southeast Kansas, southern Missouri, and into portions of the lower Ohio River valley.
