Corn earworm migration risks are back in the forecast by this weekend and into early next week as high pressure slowly drifts off into the southeast United States and low pressure organizes in the High Plains or southern Canadian prairie region. South to southwest winds are expected to increase initially across the Plains states by Saturday and continue into early next week. Low migration risks are predicted mainly west of I-35 Saturday night into Sunday, with only a slight expansion east to near the Mississippi River by Sunday night into Monday. Low risks then shift east to Lake Michigan and into Illinois by early next week. The primary concern at this point in the growing season, and given crop stages in most areas, is with any fresh market or garden/produce growers that may have susceptible vegetable crops.
