Low corn earworm migration risks are predicted tonight into tomorrow morning across the far eastern corn-growing region, including eastern Indiana, Ohio, southeast lower Michigan, and into southern Ontario, Canada. A cold front will be moving through this region over the next 24-36 hours, and short-distance moth flights from source regions in Kentucky and southern Indiana/Ohio will be possible. A break in the migration risk is then predicted for much of the week as high pressure rules the roost over much of the corn-growing region. Low risks do return to the forecast by late week and into next weekend as the next low pressure system develops in the northern Plains and southern Canada. South to southwest winds may lead to an isolated moth flight risk across much of the northern corn-growing region to the west of Lake Michigan by Friday night. Potential interaction with remnants of Harvey to the south may influence the migration risk so risks are being kept lower for the time being, but a potential increase to a Moderate risk is possible for the Labor Day weekend in some areas.
