Alert Details

As the corn-growing region transitions into the autumn season this week, the weather pattern will remain active yet rather progressive as is typical for the time of the year. As there are still some processors and fresh market growers that have crops at susceptible stages to damage especially in the northern corn-growing region east into the Great Lakes, Low risks continue in the forecast as a favorable weather pattern for isolated corn earworm moth flights will be possible from mid-week into next weekend as a cold front slowly moves through the central part of the country. Low risks are in the forecast across eastern South Dakota, Minnesota, northeast Nebraska, and northern Iowa tomorrow night into Wednesday morning as south to southwest winds increase in this area ahead of a low pressure system. Low risks continue in the foreecast across northern Iowa, southeast Minnesota, Wisconsin, northern Illinois, northern Indiana, and southwest lower Michigan Wednesday night into Thursday morning as a weak cool front moves east. By late week and next weekend, a stronger low pressure system is predicted to develop across the Plains states. This system may bring the first real shot of stronger northerly winds into the corn-growing region by the beginning of next week, but south to southwest winds in advance of the cold front may also result in isolated moth flights across much of the northern corn-growing region from eastern South Dakota and northeast Nebraska east into the Great Lakes region late week and next weekend. Growers should continue to monitor traps and subsequent forecasts especially if remaining crops are still at a susceptible stage of damage.
