Recent U.S. Drought Monitor data valid August 18, 2026, and released August 20 confirm D4 exceptional drought across portions of western Nebraska, interior Oregon, southern Idaho, Utah, and the Great Basin, driven by multi-week precipitation deficits below 25% of normal and temperatures 4–9°F above average. These conditions align with U.S. Drought Monitor percentiles placing D4 at the 0–2nd percentile of historical dryness. El Niño strengthening adds uncertainty to steering patterns and monsoon activity, while short-term forecasts through August 29 favor above-normal rainfall in parts of the East and Great Basin but continued dryness in Texas and the northern Plains. The next USDM release, expected around August 27, will incorporate the latest observations for the week of August 25 and determine state-level D4 status.
