Alert Details

A rather stagnant weather pattern will remain in place across a good portion of the corn-growing region for the next several days, but it will begin to break down by late in the weekend and early next week as a low pressure system and cold front eventually move through the area. In the meantime, with high pressure remaining anchored over the eastern corn-growing region and low pressure still across the far northern Plains and into southern Canada, south to southwest winds will remain rather persistent especially from Kansas and Missouri north into Nebraska, Iowa, Minnesota, South Dakota, western Wisconsin, and also into southeast North Dakota for the next two nights. Low risks are in place across these areas for the next two nights. By Saturday night into Sunday, the Low risk area begins to shift slightly east into Wisconsin and far western Illinois as well as northeast Missouri as the low pressure and cold front gain strength and momentum across the Plains. By Sunday night into Monday, the Low risk focuses roughly east of I-35 from northeast Kansas into southeast Minnesota, with risks as far east as southwest lower Michigan and northern/western Indiana. Fresh market and processing crops growers, especially in the upper Midwest but also in other locations further south, should continue to monitor traps and scout fields in the week ahead, or until crops are past their critical growth stages where insect damage could potentially occur as some isolated flights in this rather persistent weather pattern will remain possible.
