Alert Details

A cold front will be working its way somewhat slowly from northwest to southeast through the corn-growing region between now and early next week. Tropical Storm Harvey, presently in the western Gulf of Mexico, could potentially slow the eastward progression of this front down a little, but it may be too far removed to result in much impact as it appears now. South to southwest winds will increase already today across the Plains states and then spread east over the next few days. Low migration risks are predicted tomorrow night into Saturday morning mainly from northern Kansas and Missouri north into eastern South Dakota, Minnesota, and western Wisconsin. Low risks then spread east to Lake Michigan and the I-55 corridor in Illinois Saturday night into Sunday, and then focus mainly across the southern Great Lakes and eastern corn-growing regions east of I-55 late in the weekend and into midday Monday. Growers with crops still at susceptible stages, especially sweet corn growers and processors in the northern corn-growing region, should be monitoring traps as some flights have occurred in some areas in the last week or so, and additional flights may occur over the next several days in these same areas.
