Persistent south to southwest winds in between low pressure across the Northern Plains region and high pressure in the eastern United States along with potential precipitation episodes that may serve as insect drop zones results in a Low risk of corn earworm migration from Kansas, Oklahoma, Arkansas, and Tennessee to as far north as Minnesota, Wisconsin, and southwest Michigan for the next three nights.
