Alert Details

Low corn earworm migration risks remain in the forecast mainly west of Lake Michigan tonight into Sunday morning as a low pressure slowly churns its way from the western Plains states into the Great Lakes region over the next 2-3 days. A complicating factor to the forecast is a tropical disturbance off the east coast of the United States that is slowing the eastward progression of weather further inland, which has resulted in a slowing of the central United States low pressure system. As a result, corn earworm migration risks are being extended into the forecast into Sunday before the system weakens and moves out. Low risks remain focused from eastern Nebraska and far eastern South Dakota as far east as Lake Michigan both tonight into tomorrow night and early Sunday. Fresh market and processing growers should continue trapping and scouting efforts until harvest.
