Recent US Drought Monitor data valid through mid-to-late August 2026 show persistent D4 exceptional drought confined to limited areas of western Nebraska, parts of Colorado, northeastern Oregon, and southern Idaho, representing roughly 1.1% of the contiguous United States amid broader D1–D3 coverage of about 44%. Hot, dry conditions and flash-drought intensification in the High Plains and Intermountain West have sustained these designations, while heavy Midwest rainfall produced localized improvements. The USDM blends precipitation, soil moisture, streamflow, and vegetation indicators from NOAA, USDA, and NASA sources; D4 thresholds reflect severe, long-term deficits. Traders should watch the Thursday USDM update for the week ending around August 25–26 and CPC precipitation outlooks, which favor drier conditions across parts of the Plains and West.
