A Low corn earworm migration risk is in place across southern Nebraska, Kansas, portions of Missouri, central/southern Iowa, and western Illinois tonight into Thursday morning as a cool front slips south through the I-80 corridor. Rather weak south to southwest winds may pose a risk of isolated moth flights into this region as scattered areas of precipitation develop along the front. No migration risk is predicted Thursday night into Friday, but risks do return for the upcoming weekend and into early next week. A new area of low pressure is expected to develop in the northern Rockies and adjacent areas of southern Canada and as high pressure moves east through the corn-growing region, more organized and potentially stronger southerly winds are likely to return to especially the Plains states. As a result, Low migration risks are in place across this area and a Moderate risk has been issued for portions of Nebraska and Kansas by late in the weekend and early next week as there is enough confidence that southerly winds will be focused and stronger in this region to warrant the risk at this distance in time.
