Recent US Drought Monitor data place roughly 21% of corn acreage in drought categories as of late September 2026, with notable severe conditions persisting in parts of the northern and western Corn Belt amid variable late-summer rainfall. Dry weather forecasts from NOAA’s Climate Prediction Center for early October favor below-normal precipitation across much of the Midwest, potentially sustaining or slightly expanding affected areas ahead of the October 6 weekly assessment. Trader odds remain widely dispersed because small shifts in the Drought Monitor’s D1–D4 thresholds or regional weighting can move the national corn percentage across multiple bins; upcoming model runs and the next official map release will clarify whether conditions stabilize near current levels or diverge due to localized rainfall or persistent dryness.
