Alert Details

Black cutworm migration risks are in the forecast on a near nightly basis through the next five days as an active weather pattern is expected to remain across the corn-growing region. A combination of southerly winds prior to low pressure systems and cold fronts may bring isolated to even scattered moth flights into much of the corn-growing region through early next week. Low migration risks are predicted tonight into tomorrow morning from Kansas, eastern Nebraska, and Minnesota east as far as lower Michigan and western Ohio as a warm front lifts north through the central and into the northern corn-growing region as a cold front begins to push southeast further west. Moderate risks are predicted tomorrow night into Friday morning across Indiana, Ohio, southeast lower Michigan, and into southern Ontario, Canada as the cold front moves southeast and south to southwest winds increase ahead of the cold front, and also become positioned over more favorable source regions in the mid-south and southern Mississippi River valley. Low risks are then found across much of the corn-growing region mainly east of I-35 by the weekend as the next weather system moves through the area.
