Recent U.S. Drought Monitor data valid September 15, 2026, released September 17, shows exceptional (D4) drought persisting or expanding in portions of western and southern states including southern Idaho, northern Nevada, northeastern Oregon, far south and northern Texas, western and southern Oklahoma, parts of Arkansas, and scattered areas of Colorado, where D4 coverage rose to 15.2 percent amid the contiguous U.S. record-warm June–August period and below-normal precipitation that sustained drought across nearly half the country. Authoritative assessments from the National Drought Mitigation Center, NOAA, USDA, and NASA integrate precipitation deficits, soil moisture, streamflow, and evaporative demand to classify conditions on the D0–D4 scale. Trader sentiment reflects limited near-term relief prospects, with the next weekly map update scheduled for September 24 based on data through September 22 potentially shifting odds if late-September rainfall alters intensity in key states.
