Alert Details

A couple of quick-moving cold fronts in increasing northwest dominant flow may bring some isolated corn earworm moth flights to the corn-growing region in the next five days or so. The first Low risk is tonight into tomorrow mainly from far northern Kansas and Missouri as far north as Minnesota and Wisconsin as a somewhat brief period of southerly winds may allow for some migration to the north ahead of the frontal passage. The second Low risk period comes in this weekend in the Saturday night into Sunday time frame. The weekend front looks stronger and should bring the first cold push of autumn air south into the corn-growing region early next week. Low risks are predicted from the Plains as far east as Michigan and northwest Ohio at that time.
