Alert Details

A very active and progressive weather pattern is predicted to continue for the next week across much of the corn-growing region. With some processors and fresh market growers still actively growing crops especially in the northern corn-growing and Great Lakes region, a continued risk of corn earworm migration will accompany this more active weather pattern. Low risks are predicted overnight tonight into tomorrow morning especially across far eastern Illinois, southern lower Michigan, northern Indiana, northern Ohio, and southwest Ontario, Canada as the first cold front moves through. Once this front clear the corn-growing region, attention then shifts back west of the Great Lakes as the next low pressure system develops in the Plains. Low risks are in the forecast across northern Iowa, Minnesota, and Wisconsin Sunday night into Monday as south to southwest winds increase ahead of a cold front trailing south of the low pressure. Additional Low risks are also in the forecast across northeast Nebraska, eastern South Dakota, Minnesota, northern Iowa, and far western Wisconsin next Tuesday night into Wednesday as south to southwest winds continue to the east of a potentially third cold front that develops next week. Growers with crops at susceptible stages should continue to monitor traps and treat as needed in the next week.
