Recent U.S. Drought Monitor data valid August 18, 2026, show exceptional (D4) conditions covering roughly 1.3% of the contiguous United States, concentrated in pockets across western Oklahoma, the Texas Panhandle, eastern Colorado, Wyoming, western Nebraska, parts of Idaho, and northeastern Oregon. These areas reflect persistent above-normal temperatures, below-average monsoon rainfall, and rapid soil-moisture depletion characteristic of flash drought. The weekly map scheduled for release around August 27 will incorporate observations through late August, when NOAA outlooks indicate continued above-normal temperatures nationwide alongside mixed precipitation signals that favor drier conditions across the southern Plains. Traders monitor short-term model runs and any late-month rainfall that could shift D4 polygons enough to alter the exact state count.
