**Flash drought driven by persistent hot, dry weather across the southern Great Plains and into the Mississippi River Valley has rapidly intensified conditions, expanding exceptional (D4) drought areas in multiple states.** The U.S. Drought Monitor, produced by the National Drought Mitigation Center with NOAA and USDA input, classifies D4 based on extreme precipitation deficits, depleted soil moisture, low streamflows, and agricultural impacts relative to historical baselines. Recent weekly summaries note degradation from Texas northeastward through Oklahoma, Kansas, Missouri, Arkansas, and adjacent areas, with additional D4 pockets in parts of the northern Plains, Idaho, Colorado, and isolated Southeast locations such as North Carolina. This has elevated the number of affected states, aligning with market-implied odds favoring 10 or more states (57%). Warmer-than-normal temperatures have amplified evapotranspiration, while the lack of relief precipitation sustains the trend; the next USDM update will incorporate any late-week changes before final resolution.
