Recent U.S. Drought Monitor data valid August 18, 2026, show exceptional (D4) drought covering roughly 1.1% of the contiguous United States, concentrated in limited pockets amid broader D1–D3 conditions affecting over 44% of the nation. Primary drivers include persistent precipitation deficits and above-normal temperatures across the Northern and Southern Plains and Northwest, where conditions have continued to degrade, while scattered rainfall has eased drought in parts of the Eastern Seaboard, Central Plains, and Upper Midwest. The upcoming map, scheduled for release August 27 and reflecting conditions through approximately August 25, will incorporate the latest NOAA precipitation and temperature analyses plus soil moisture and streamflow indicators. Traders should monitor short-term forecast shifts and any late-August rainfall that could alter D4 boundaries before the weekly assessment closes.
