**Recent rapid degradations driven by persistent high pressure and extreme heat have intensified drought across the Southern Plains, Upper Midwest, and parts of the Lower Mississippi River Valley, pushing several states toward or into extreme (D3) conditions just days before the U.S. Drought Monitor map for the week of September 1, 2026 (data valid ~August 31).** The latest USDM, released August 27 and valid through August 25, shows no nationally significant exceptional (D4) coverage, with D4 at or near 0% in most states and only isolated or zero reports in affected regions. However, Minnesota saw its extreme drought area expand nearly fivefold in one week amid widespread severe (D2) coverage, while degradations continued in North Dakota and the south-central U.S. under above-normal temperatures exceeding 100–110°F. Authoritative sources (USDM/NDMC, NOAA CPC, Drought.gov) note that D4 represents the most intense category, typically requiring multi-month precipitation deficits, critically low soil moisture/groundwater, and major agricultural or water-supply impacts. Key upcoming drivers include the next USDM release (expected ~September 3–4), which will directly determine the September 1 week outcome, plus the CPC Seasonal Drought Outlook update on September 17. A strong El Niño is favored to influence fall patterns, with potential persistence or expansion in the northern Plains/Northwest but relief signals in the Southwest and Southeast. Flash drought timing and any late-August rainfall could still shift conditions before the map locks in. Traders should monitor official weekly updates and model consensus on precipitation deficits relative to long-term baselines.
