Nebraska's 2026 harvest has been strongly affected by weather, with yields subpar and some fields producing nothing in the worst cases. Flooding from heavy September rain damaged ditches, roads and fields, and wet conditions continue to slow harvest.
Lower state corn output tightens regional supply and supports cash prices for feed buyers in the Plains. The effect on national prices is limited because Nebraska is a modest share of total US production.
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.
