A cold front is expected to begin accelerating to the east over the next 24-48 hours, and should be largely out of the corn-growing region by the end of the week. Before this happens, however, another night of potential black cutworm migration risk is in store mainly for fields along and east of the I-55 corridor from southeast Missouri through Illinois. A lack of southerly wind flow precludes much risk over the weekend. By late in the weekend and early next week, however, southerly winds are expected to increase across the Plains as the next weather system develops in the Rockies and temperatures warm. Low risks are back in the forecast mainly west of I-35 by Sunday night into Monday morning. Growers with newly emerged corn should continue scouting for black cutworm larvae until the crop is advanced enough in growth that the crop is not at risk of cutting/feeding damage.
