Recent U.S. Drought Monitor data valid August 18 show D4 exceptional drought persisting across portions of Colorado, western Nebraska, northeastern Oregon, southern Idaho, western Oklahoma, the Texas Panhandle, and southeastern Arkansas, driven by record July heat, long-term precipitation deficits, and limited monsoon relief in the Intermountain West. These conditions reflect multi-indicator assessments of soil moisture, streamflow, and vegetation stress compiled by NOAA, USDA, and NASA. Above-normal temperatures forecast through late August are expected to sustain or intensify dryness in these regions, while variable short-term rainfall offers only localized improvement. The next USDM update, covering data through August 25 and released August 27, will incorporate the latest precipitation and temperature observations; traders should monitor National Weather Service outlooks for any shifts in the 6–10 day period that could alter D4 extent by state.
