A weekend snow and wind storm damaged ripening wheat across Kansas, Colorado, Oklahoma and Nebraska, and forecasters expected more heavy rain across the Mississippi Valley. Early estimates put crop losses above 50 million bushels.
Chicago wheat posted record one-day gains, with hard red winter futures up 6.5 percent and soft red winter up 5.5 percent, while corn also climbed.
Losses above 50 million bushels and record price gains point to a real tightening of U.S. wheat supply, and flooding in the Midwest adds risk to corn planting. Buyers of feed grains should expect firmer prices while losses are confirmed.
