Alert Details

A more progressive weather pattern is predicted to take hold across the corn-growing region in the next week. The result will be more limited possibilities for corn earworm migration given the expected quicker movement of weather systems in comparison to the past few weeks. A Low risk is in the forecast tomorrow night into Friday morning across much of Kansas, eastern Nebraska, southern Minnesota, southern Wisconsin, Iowa, Missouri, and much of Illinois as the next low pressure system develops and as southerly winds return to the western corn-growing region. The risk then shifts into the eastern corn-growing region, mainly east of I-55, on Friday night into Saturday as a cold front south of the low pressure sweeps through the area. Any migration events during this time are predicted to be isolated, at best. Growers are advised that with recent southwest flow weather patterns in place that there may not be a risk to corn crops at this time, but some fruit and vegetable crops may be at risk at seeing some feeding especially in the Great Lakes region.
