Alert Details

A cold front is still expected to move southeast through the central and eventually eastern corn-growing region over the next 24-36 hours. Ahead of the front, south to southwest winds along with at least scattered areas of precipitation may lead to some isolated corn earworm migration possibilities mainly along/east of the I-55 corridor from southeast Missouri through central Illinois and east of Lake Michigan tonight into tomorrow. Little to no risk is predicted for mid-week as northwest flow should dominate the weather, but already by late week and into next weekend, southerly winds return to the Plains and eventually western/central corn-growing regions and Low risks are in place as far east as Lake Michigan and into Illinois by Friday night into Saturday. The primary threat at this point remains with fresh market/processing/garden growers as field corn is not at a susceptible stage to damage quite yet. Some portions of the southern corn-growing region may begin to see some increased pressure in the next few weeks as pollination of field corn commences.
