The U.S. Drought Monitor map for data valid August 25, 2026, released August 27, shows D4 exceptional drought expanding or persisting primarily across the Southern Plains, Lower Mississippi Valley, and parts of the Intermountain West due to a persistent heat dome, below-normal precipitation, and rapid soil moisture depletion. Authoritative indicators from NOAA, USDA, and the National Drought Mitigation Center highlight major degradations in Oklahoma, Arkansas, Mississippi, Idaho, and Oregon, where D4 coverage reached several percent of state area amid extreme temperatures and groundwater declines. Scattered improvements occurred in the Northeast from recent storms, while the Upper Midwest saw further intensification. The next weekly USDM update, incorporating new precipitation, streamflow, and vegetation data, will determine any shifts in state-level D4 presence ahead of resolution.

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.
The resolution source for this market is the US Drought Monitor at droughtmonitor.unl.edu.
