Late September and October rainfall eased Midwest drought and raised Mississippi River water levels, after summer drought affected much of Minnesota, Iowa and Wisconsin. USDA projects a relatively limited impact on average crop yields.
Fall water levels had dropped to their lowest September levels in years before the rains.
Improved river levels make a repeat of last year's barge backlog less likely, easing freight pressure on grain movement. Limited yield losses also reduce the upside risk for corn and soybean prices.
