Corn earworm migration risks return to the forecast Wednesday night into Thursday morning ahead of a southeastward-advancing cold front. Mainly light south to southwest winds ahead of this front may lead to some isolated moth flights from far northeast Kansas, northern Missouri, and southern Illinois north into Iowa, Minnesota, northern/central Illinois, and Wisconsin during this time period. The Low risk advances east into the southern Great Lakes and eastern corn-growing region Thursday night into Friday morning as the cold front moves southeast. Mainly light winds and short duration of favorable wind direction precludes a higher risk at this time despite the time of year, full moon, and host plants becoming less favorable hosts across the southern corn-growing region and mid-south areas of the country. A potential change in the weather pattern by next weekend and into next week may lead to higher risks at that time.
