Alert Details

The active weather pattern is predicted to continue right into the middle of next week when a cold front should finally push southeast through much of the corn-growing region. Until then, black cutworm migration risks remain in the forecast on an almost nightly basis. Moderate risks are predicted tonight into tomorrow morning from northeast Iowa into northern Illinois, Wisconsin, southwest lower Michigan, and northern Indiana as south to southwest winds are maximized along/east of a cold front, and also where precipitation is likely to occur. Low risks extend east into far southwest Ontario, Canada and Ohio, as well. Low risks are in the forecast tomorrow night into Sunday morning mainly east of I-35 into the Great Lakes region and eastern corn-growing area. By early next week, the main cold front should push southeast through the corn-growing region by mid-week, but with south to southwest winds in place east of the front, Low risks are in the forecast initially across the Plains on Monday night and Tuesday but then push east as far as southwest lower Michigan and Indiana by Tuesday night into Wednesday. Growers that have recently planted or have yet to plant should pay close attention in those fields as moth flights in the last week could affect emerging and early vegetative stage corn next month.
