Alert Details

Low corn earworm risks are in the forecast for the next five days as a low pressure system currently in Montana advances east into the far northern Plains states/southern Canada. Southerly winds are expected to expand east across the corn-growing region as high pressure currently across the Great Lakes region shifts to the south and east into the southeastern United States. Despite migration risks for the next five days, only Low risks are predicted due to weaker high and low pressure centers which are expected to limit the magnitude of south or southwesterly winds. Low risks are initially in place across Nebraska and Kansas tonight into Thursday morning and then expand north/east into areas generally west of I-35 and south of US 12 Thursday night and Friday (South Dakota/Minnesota southwest). Virtually all of the corn-growing region from Nebraska and Kansas east into Ohio and Michigan is under a risk for potential isolated moth flights at some point in the extended forecast period as a cold front south of the low pressure advances east.
