Hot extremes have become drier in the United States Southwest

Nature Climate Change, Published online: 17 June 2021; doi:10.1038/s41558-021-01076-9

Global humidity increases with warming, but the United States Southwest has shown summer decreases since 1950, with the largest declines on hot days attributed to decreased soil moisture, not atmospheric moisture transport. Projections are uncertain due to model spread in precipitation trends.
