Alert Details

A cool front will be moving southeast through at least the northern half or so of the corn-growing region. While the front will do little to lowering temperatures, it is more of a weak wind shift and dew point gradient front and will also serve as a dividing line between potential isolated corn earworm moth flights and not to its west. Low migration risks are predicted generally west of Lake Michigan and the I-55 corridor through central Illinois and southeast Missouri tonight into tomorrow. After tomorrow, wind flow is not supportive of a risk through early next week so little to no risk is predicted. Growers with crops at susceptible stages to damage, however, should continue monitoring traps and scouting fields as some isolated moth flights are still possible.
