Alert Details

A cold front is expected to move southeast through much of the corn-growing region over the next two-three days. This front will serve as a dividing line between south to southwest winds to its east and northwest winds on its backside, and precipitation is likely at least in a scattered fashion along and ahead of the front. Corn earworm possibilities will be focused just east of the front, with Low risks tonight mainly west of the Mississippi River. Low risks then focus a little further east tomorrow night into Thursday from Kansas north into eastern South Dakota and potentially as far east as southwest lower Michigan and into Indiana. With corn advancing into silking/pollination stage now in some areas, growers should be more vigilant about checking traps and scouting fields as some flights may occur in isolated areas. Little to no risk is predicted late week into next weekend as northwest flow is expected to dominate the weather pattern by then.
