A continued northwest to southeast wind flow in the weather pattern is expected to result in a continued Low or no corn earworm migration risk through the weekend. Low risks are focused primarily across the central Plains and southwest Midwest, or from Kansas and Nebraska east into portions of southern Iowa and Missouri. By early to mid next week, there are signs that a cold front is likely to push southeast through much of the corn-growing region. There will likely be at least a period of south to southwest winds ahead of this front that should originate from very favorable source regions across the mid-south region. As a result, Low corn earworm migration risks do expand north and east into portions of the upper Midwest and Mississippi River valley, and a Moderate risk is predicted for portions of Kansas, Missouri, Iowa, Illinois, Wisconsin, Michigan, Indiana, Kentucky, Ohio, and southwest Ontario, Canada with the frontal passage next Tuesday into Wednesday. Continue to monitor updates early next week, and also be alert for second generation moth appearances in the next week or so all across the corn-growing region.
