A slow-moving yet potent cold front is predicted to develop in the Plains states late this week and then move through much of the corn-growing region over the weekend and into early next week. South to southwest winds are likely to be found to the east of the front, and may provide some isolated corn earworm moth flight possibilities into remaining processing and fresh market fields especially in the northern corn-growing region and Great Lakes area. Low risks are predicted mainly west of I-35 tomorrow night into Saturday morning as south winds increase in that region. The risk then shifts into Iowa and Minnesota east to Lake Michigan Saturday night into Sunday morning, and finally east of the Mississippi River late in the weekend. As the cold front continues to move east, the southern Great Lakes region should see the possibility for some isolated moth flights next Monday night into Tuesday. Growers with crops still at susceptible stages should continue to monitor traps and subsequent forecasts for the latest information.
