A cold front will continue to push southeast through the corn-growing region in the next 48 hours. As high pressure moves east into the eastern United States, south to southwest winds will increase to the east of the front. These southerly winds may result in an isolated risk of corn earworm migration into any remaining fields still at susceptible stages to damage tonight into tomorrow morning especially across the eastern Plains states into the upper Midwest and western Great Lakes region, or from eastern Nebraska and South Dakota into Minnesota, Iowa, northern Illinois, Wisconsin, southwest Michigan, and northwest Indiana. The cold front will press into the Great Lakes and eastern Midwest tomorrow night into Sunday, but as it does so it is expected to weaken and southerly winds in advance of the front will not be as conducive for moth flights, thus no risk is predicted past tomorrow morning.
