August flooding after more than 12 inches of rain in parts of the Midwest lodged crops and created uncertainty over final yields. USDA's Crop Progress report showed the national corn condition rating fell to its lowest level of the season, and harvest began ahead of normal.
USDA's production update is due Friday.
Falling crop ratings and flood damage raise the risk of lower corn and soybean yields, which supports feed grain and meal prices ahead of USDA's report.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
