U.S. Department of Agriculture analysis of the July 31 U.S. Drought Monitor from Brad Rippey, USDA meteorologist, Office of the Chief Economist, shows that:
Bottom line: There was further drought intensification in the hardest-hit areas of the Plains, Midwest, and Mid-South, but some slight improvement in the overall drought situation in the eastern U.S. Contiguous U.S. drought coverage dipped nearly one percentage point, from 63.86 to 62.91 percent.
