In the South, improvements were made across areas of the eastern half of Texas, southeastern Oklahoma, western Arkansas, and southern Mississippi where locally heavy rainfall accumulations (3 to 8+ inches) were observed. Despite this week’s rainfall in portions of Texas, streamflows in the Hill Country remain below normal with numerous gauging stations reporting levels in the bottom 10th percentile, according to the USGS. In terms of reservoir storage in Texas, monitored water supply reservoirs statewide are currently 69.9% full, according to Water Data for Texas. Some low reservoir storage levels are currently being observed in the western half of the state, including at Medina Lake (west of San Antonio) which is currently 6.7% full. According to NOAA NCEI, the South Climate Region experienced its 13th driest (-2.34-inch anomaly) September-October period on record, with Louisiana observing its 6th driest (-4.35–inch anomaly) for the contemporaneous period.
