Alert Details

A rather persistent late-summer weather pattern is predicted for much of this week and even into next weekend, with low pressure in the High Plains and high pressure across the eastern United States. In between, southerly winds are likely especially to the west of the Great Lakes for much of this week. These winds may lead to some isolated corn earworm moth flights, with at least some potential of scattered flights especially later in the week, mainly west of the Great Lakes region. Low risks are predicted mainly west of I-55 and Lake Michigan tonight into tomorrow, with the risk focusing mainly southeast of a line from east of Goodland, Kansas to Minneapolis, Minnesota tomorrow night into Wednesday. Low risks do eventually expand east into a portion of southwest lower Michigan into Indiana by the weekend, but greatest risks through much of this week appears to stay west of the Great Lakes. Growers with crops at critical stages of growth, especially late planted field corn and processing/fresh market sweet corn and other vegetables, should continue scouting efforts and trapping until the crop move past critical growth stages and/or is harvested.
