A favorable weather pattern for corn earworm migration will remain across at least portions of the corn-growing region through mid-week before northwest flow shuts down any potential migration chances (at least for a little while) by late week and into the early portion of next weekend. Moderate risks are predicted tonight into tomorrow from Missouri and southeast Iowa northeast into Illinois, Indiana, southern lower Michigan, northern Ohio, and southern Ontario, Canada as a corridor of south to southwest winds along with at least scattered precipitation chances may lead to scattered moth flights into this region. Additional Moderate risks are in the forecast tomorrow night into Wednesday further west ahead of the main cold front in northeast Kansas, far eastern Nebraska, Missouri, Iowa, Minnesota, Wisconsin, Illinois, and just east of Lake Michigan in southwest lower Michigan and northern Indiana with Low risks north and east from the Moderate risk area. Wind flow becomes more westerly and eventually northwesterly by late Wednesday into Thursday with Low risks focusing mainly across the southern Great Lakes and eastern corn-growing region. Growers all across the corn-growing region, especially those with crops at susceptible stages to damage from corn earworms, are encouraged to monitor traps and scout fields as some flights may have recently occurred since last week and this past weekend, with additional flights possible at least for the next few nights.
