Alert Details

A stagnant weather pattern is predicted to continue across much of the corn-growing region for the next several days until a cold front finally pushes through most fields by early-mid next week. Ahead of this happening, however, very warm to hot conditions (for late September) are predicted especially west of the Great Lakes, and this is also the same area that has a Low risk through the weekend and into early next week, as well. Low risks are found mainly west of Lake Michigan as south winds continue through Sunday morning, with the Low risk extending east into southern Michigan and northern Indiana as well as northwest Ohio into Monday morning. By early next week, however, the parent low pressure system in the far northern Plains and southern Canada should be weakening, and a cold front will likely push southeast through the area. This will change winds back to the northwest and end any migration threat. Until that time, however, remaining processing and fresh market growers should continue to monitor traps and scout fields for signs of new moth arrivals at least into early next week.
