**Persistent dryness across the High Plains and interior West, combined with above-normal temperatures and limited recent rainfall, continues to sustain pockets of exceptional (D4) drought in states such as Nebraska, Colorado, Oregon, and Idaho as of the August 20 U.S. Drought Monitor map (data through August 18).** These conditions reflect the most severe category on the scale, typically corresponding to the 0–2nd percentile of historical dryness with widespread impacts on agriculture, water supplies, and ecosystems. Recent heavy rainfall (often exceeding 5 inches in parts of the Midwest and central Plains) has improved conditions in Iowa, Illinois, Indiana, and eastern areas, while the southern Plains and Texas have seen degradation under high pressure and minimal precipitation. The West Coast and northern Great Plains remain largely dry, with monsoonal activity providing only scattered relief in the Southwest. Overall, D4 covers roughly 1.1% of the contiguous U.S., concentrated in these limited western and Plains regions. The next U.S. Drought Monitor map (expected release around August 27, based on data through August 25) will determine the week-of-August-25 outcome. Key inputs include the National Weather Service 6–10 day outlook (August 25–29), which favors above-normal precipitation along the northern Eastern Seaboard and parts of the Midwest but below-normal rainfall in Texas, alongside well-above-normal temperatures across most of the Lower 48. These factors, along with ongoing soil moisture, streamflow, and evapotranspiration data from NOAA and partners, will drive any expansion, contraction, or persistence of D4 areas. Trader sentiment reflects uncertainty around whether dry, hot conditions will maintain or add to the current four states with D4.

D4 area below 0.05% is treated as cartographic noise at state borders and resolves "No".
Alabama carries a market in May through November, so this market exists for the week valid August 25, 2026. Weeks outside that window have no Alabama market and make no claim about Alabama's drought.
Each USDM release covers the seven-day period ending Tuesday at 8:00 AM ET and is published the following Thursday.
Resolution is based on the first published US Drought Monitor release for the listed week. Subsequent revisions will not be considered; the first published release is final.
