As one weather system departs the eastern corn-growing region, the next one is already developing in the Rocky Mountains and spreading southerly winds across the Plains and western corn-growing region. Low corn earworm migration risks are predicted tonight into tomorrow mainly west of I-35, with Low risks then expanding east from Kansas, eastern Nebraska, and southeast South Dakota as far east as the I-69 corridor in Kentucky, Indiana, and southwest lower Michigan by tomorrow night into Saturday. Over the weekend, as a cold front begins to push southeast through the corn-growing region, Moderate risks are predicted mainly across northern Missouri, eastern Iowa, southeast Minnesota, Wisconsin, and northern/central Illinois with Low risks as far east as I-75 in lower Michigan, western Ohio, and into Kentucky. Growers are advised to continue to regularly check traps and fields as corn earworm flights have occurred and new moths and potential larvae from previous flights are likely to begin appearing in some fields, if not already.
