A cold front is pushing its way south and east through the corn-growing region at the present time, and should continue through much of the area by tomorrow. Before it does so, however, a Low corn earworm migration risk in continued south to southwest winds and scattered precipitation areas will exist across the Great Lakes and eastern corn-growing region. Fields still at susceptible stages to damage especially along and east of I-55 may see an isolated moth flight tonight into tomorrow morning. The risk includes eastern Illinois, Indiana, Ohio, southern and central lower Michigan, northern Kentucky, and southwest Ontario, Canada. No additional risks are predicted after midday tomorrow as northwest flow locks back in across much of the corn-growing region and ends the threat of any southerly winds across the corn-growing region.
