Recent U.S. Drought Monitor data show roughly 21% of corn acreage in moderate or worse drought (D1+) as of late September 2026, down slightly week-over-week amid mixed precipitation patterns. Flash drought intensification from August-September heat and rainfall deficits has affected the eastern Corn Belt and southern Plains, while remnants of Hurricane Polo and earlier northern rains eased conditions in parts of the central and western regions. Key variables for the October 6 resolution week include ongoing soil moisture trends, temperature anomalies that accelerate evapotranspiration, and any late-season frontal systems that could shift the percentage into adjacent bins such as under 15% or 25-34%. The USDA’s weekly Ag in Drought report, derived from the National Drought Mitigation Center’s blended indices, will determine final classification against historical baselines for corn-producing states.
