Alert Details

Low corn earworm migration risks are predicted mainly east of I-35 from northwest Missouri and central Iowa east into Wisconsin, Illinois, lower Michigan, Indiana, and western Ohio tonight into tomorrow morning as a cool front pushes southeast through the corn-growing region. Showers and thunderstorms are likely ahead of the front and may serve as a drop zone region for any migrating corn earworm moths. With the majority of crops in an unfavorable growth stage where damage could occur, only Low risks are in the forecast at this time. Once this front moves through, Low risks focus mainly across the Plains and western corn-growing region for the remainder of the forecasting period (into next weekend) as new low pressure systems develop in the far western Plains. By late in the weekend, Low risks do push further east closer to the Great Lakes, but the primary risk area, albeit Low, will remain west of I-35 in the Plains through the week.
