Corn earworm migration risks remain in the forecast on a nightly basis through early next week when a weather pattern change does appear to occur, with more of a northwesterly flow and likely at least somewhat cooler and drier conditions. Before that point, however, southerly winds will continue to flow north from source regions in Texas and Oklahoma, and on these same winds may be some migrating corn earworm moths. Winds are not expected to be overly strong, so only Low risks are predicted tonight into tomorrow for a pretty large area from the Plains states all the way east into Indiana and western Kentucky. Low risks continue tomorrow night into Sunday over a similar area but not quite as far north in the western Great Lakes region. It appears that the greatest concern for migration chances comes late in the weekend and early next week when a cold front begins moving south into the corn-growing region. Southerly winds interacting with a front and likely at least scattered precipitation may lead to more scattered moth flights especially from Iowa and Minnesota east into southern Wisconsin, Illinois, northern Indiana, far northwest Ohio, and southern lower Michigan where a Moderate risk is in place Sunday night into Monday. Risks may continue Monday night into Tuesday, as well, especially across the southern Great Lakes but much depends on what happens with precipitation Sunday night as to what may occur Monday night. Regardless of the risk by next week, growers all across the corn-growing region should be monitoring traps and regularly scouting fields as many corn earworm moth flights have occurred in earnest and also earlier than usual this year compared to the past, especially given favorable conditions in late June and early July. Additional flights will remain possible through early next week.
