Corn earworm migration risks will return to the forecast by this weekend and into next week as a more active weather pattern returns to the corn-growing region. Low risks are back in the forecast by Saturday night into Sunday morning especially from Kansas and western Missouri north into Nebraska, Iowa, eastern South Dakota, central and southern Minnesota, and far western Wisconsin as southerly winds increase to the west of high pressure that is predicted to slowly move east through the Ohio River valley. Low pressure is predicted to develop across the far northern Plains and into southern Canada with a cold front to its south, and this front may spark showers and thunderstorms which could serve as drop zone regions for any migrating corn earworm moths. The risk shifts further east as the cold front moves east Sunday into Monday, and fields mainly west of Lake Michigan and into Illinois will be at risk by that time. Low risks then re-focus back across Kansas, southern Nebraska, southwest Iowa, and western Missouri next Monday night into Tuesday as another low pressure looks to develop in the central Plains by that time. Additional risks are possible next week, so growers with crops at susceptible stages should monitor subsequent forecasts as well as their traps and field activity as we move into this weekend and next week.
