Alert Details

As the next in a continuing series of low pressure systems moves across the Plains into the upper Midwest in the next two days, south to southwest winds in advance of a trailing cold front to the south of the low pressure center may result in isolated corn earworm moth flights into portions of the corn-growing region. Low risks are in place tonight into Saturday morning across much of Kansas, eastern Nebraska, far southeast South Dakota, southern Minnesota, Iowa, Missouri, western Illinois, and southwest Wisconsin. As the front moves east Saturday, the risk area also shifts a little bit to the south and east with risks into fields as far east as Indiana. While corn in many locations is not at a susceptible stage to damage, other crops, vegetables, and host plants may see additional moths in the coming days and growers should be on the lookout for new migrants. No risk is predicted in the extended period as high pressure builds into the Midwest and keeps any southerly winds confined to source regions in the mid-south and southern states.
