The overall weather pattern is predicted to shift from a predominantly northwest to southeast flow into a potentially more active southwest to northeast flow by late week and into the weekend. Until this transition occurs, no migration risk is predicted through Friday but Low risks do return to the Plains states by Friday night into Saturday as the process begins to take shape and southern winds return especially to Kansas and Nebraska. A more broad Low risk region is predicted thereafter across much of the southern two-thirds of the corn-growing region as light to occasionally moderate south to southwest winds remain rather persistent. Rainfall will also be a factor in such a pattern and we are moving past the time when first generation moths are more active especially across source regions in the mid-south. As a result, only Low risks are predicted at this time but growers are advised that some isolated moth flights are likely to occur into some portions of the Midwest especially next week.
