Low corn earworm migration risks are predicted tomorrow night into Friday morning generally along and east of the Mississippi River into the southern Great Lakes and eastern corn-growing regions. A cold front is likely to move through much of the area by late week and into the weekend, with a brief period of southerly flow ahead of the system. Much of the corn-growing region is in northwest flow, and brief periods of southerly winds ahead of cold fronts in such a flow regime seldom produce more than isolated moth flights due to the relatively short time that moths can migrate north. Low risks are in place from eastern Missouri, Illinois, and southern Wisconsin east into lower Michigan, Indiana, and Ohio during this time. No other risks are predicted in the next five days.
