A new area of low pressure across the central Plains states will result in increasing southerly winds across especially the Plains into portions of the corn-growing region, especially west of the Mississippi River and south of I-90 tonight into tomorrow morning. Low risks mainly for isolated moth flights are predicted across northern Kansas into Missouri, Iowa, Nebraska, and far southern Minnesota and extreme southern South Dakota. Low pressure will move slowly east tomorrow into Saturday, with high pressure drifting off to the southeast into the southeastern United States. Increasing south to southwest flow is expected to the east of the low pressure system and trailing cold front, and it is possible that some scattered black cutworm moth flights will occur especially from eastern and northeast Iowa into far southern Wisconsin, northern Illinois, northern Indiana, and also into far southwest lower Michigan tomorrow night into Saturday morning. A Moderate risk has been issued for these areas, with a Low risk essentially east of I-35 in central Iowa all the way into southern Ontario, Canada and Ohio. After midday Saturday, it appears wind flow will become increasingly westerly or the primary migration risk focused far enough south that concerns over black cutworms will not be a concern. As a result, no additional migration risks are predicted into early next week from midday Saturday on.
