Rain left Iowa farmers with only 1.7 suitable fieldwork days during the week, slowing harvest. By November 8, corn harvest was 72% complete, 17 percentage points behind the five-year average, while soybean harvest was 93% complete, two points behind average.
Drier weekend conditions offered farmers a chance to resume fieldwork.
Delayed fieldwork can extend the period when unharvested crops are exposed to weather and may constrain near-term grain movement, lending modest support to corn and soybean prices. A favorable forecast and resumed harvesting could limit that support.
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.
