Persistent heat and sparse late-summer rainfall have driven rapid drought expansion across the Southern Plains, Lower Mississippi Valley, Upper Midwest, and portions of the Intermountain West, producing D4 conditions in states including New Mexico, Idaho, Nevada, Arkansas, Mississippi, and Nebraska on the U.S. Drought Monitor map valid August 25, 2026. Above-normal temperatures increased evaporative demand while monsoon activity provided only localized relief in the Southwest; soil moisture, streamflow, and groundwater metrics fell to exceptional levels in affected regions. The National Drought Mitigation Center, NOAA, and USDA partnership releases the next map on September 3, with additional updates possible from regional outlooks incorporating El Niño influences on fall precipitation patterns.

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.
