The latest update of topsoil moisture from USDA shows the percentage of topsoil in very-short and short status by state has remained relatively steady over the last four weeks for much of the U.S.
There are some big exceptions, however. Some of the largest changes in topsoil have been observed in the Southeast and parts of the West/Southwest where the percentage of topsoil in the very-short/short status has increased 30 points or more (e.g. Colorado, Georgia, Arkansas, Alabama, Tennessee, and Kentucky).
The decline in topsoil is likely a result of a combination of plant growth, above-normal temperatures, and poor rainfall in these areas.
