Heat alerts were issued across the Midwest and Northeast as temperatures were forecast above 90°F through the weekend. Crops in the central Corn Belt have not yet reached reproductive stages and should handle the heat better, but farms in the South are already reporting possible crop failure.
Silking has started in the South, where heat could reduce ear size and kernel count.
Heat during silking in southern regions could lower corn yields and add to supply concerns, supporting corn prices.
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.
