A cold front will be passing through much of the corn-growing region over the next 48 hours or so. Ahead of the front, south to southwest winds will be present but not in an overly strong fashion. Scattered to organized areas of precipitation will also occur near the front and could serve as drop zones for any migrating insects. Low corn earworm migration risks are predicted tonight into tomorrow from southeast Kansas northeast into the southern Great Lakes and eastern corn-growing region, with Low risks continuing in the forecast tomorrow night into Friday mainly from southeast Missouri northeast into the Great Lakes/eastern corn-growing region. Little to no risk is predicted thereafter, but growers with crops at critical growth stages, including an increasing amount of field corn, should monitor traps and scout fields given the potential for at least isolated flights.
