Recent US Drought Monitor data valid September 15, 2026, show exceptional (D4) drought covering about 2% of the contiguous United States, concentrated in central Colorado, portions of New Mexico, Idaho, Texas, Arkansas, Nebraska, and smaller areas of Mississippi and North Carolina. Record summer heat and below-normal precipitation have driven flash drought intensification across the southern and western Plains and Southwest, with limited relief from recent rains in isolated eastern zones. The next map, released September 24 and valid through September 22, will incorporate any late-week precipitation or temperature shifts that could alter D4 boundaries before resolution. Traders monitor National Weather Service outlooks and soil moisture trends for potential short-term improvements in marginal areas.
