Corn earworm migration risks will continue in the forecast on a nightly basis until a cold front passes through much of the corn-growing region early next week. Low risks are predicted tonight into tomorrow morning mainly across Kansas, Nebraska, Iowa, Missouri, and into Illinois as southerly wind flow is expected to be a little weaker and also precipitation may limit overall northward progress of some moths. Moderate risks, however, enter the forecast tomorrow night into Sunday morning from far eastern Nebraska into Iowa, Minnesota, Wisconsin, and Illinois with Low risks east into the southern Great Lakes region as the strong cold front advances southeast into the Plains states. Again, precipitation and its location may impact flights somewhat, but the overall weather pattern and crop stage both in the source region and across the corn-growing region warrants an elevated risk. Moderate risks continue in the forecast Sunday night into Monday morning mainly across the southern Great Lakes region, but some scattered flights may occur as far west as near the Mississippi River and isolated moth flights may be seen into Ontario, Canada as well as Ohio. No additional risks are predicted after Monday morning once the cold front moves through, but growers should monitor traps and scout fields next week as some moth flights are likely this weekend at least on an isolated/scattered basis.
