Alert Details

A cold front will continue to push east through the corn-growing region over the next 24-36 hours. Ahead of the front, showers/storms will persist across Iowa and the Mississippi River valley but should die out later today in most areas. South to southwest winds are only expected to be modest to the east of the front, but given the time of year and crop stage in the mid-south and southern corn-growing areas, corn earworm moths may still be able to move north and a Low risk for mainly isolated moth flights is predicted from near Kansas City, Missouri northeast to Milwaukee, Wisconsin and points east late today into early tomorrow morning. Once the front clears the eastern areas, no risk is then predicted until late Friday into next weekend as southerly flow returns to the Plains states. Low risks are predicted mainly west of I-35 at that time.
