As the latter half of September rolled around, rainfall across the Rio Grande Valley and Deep South Texas began to taper off. Spotty showers and thunderstorms dropped a few tenths more rain across the lower and mid Valley, while the upper Valley and northern ranchlands saw some heavier activity towards the 20th and the 21st. Nevertheless, this rainfall combined with the beneficial rainfall from earlier in the month, allowed for drought conditions to continue to improve, with many Severe (D2) drought conditions prevailing across large portions of Jim Hogg, Starr, Brooks, Hidalgo, Kenedy, and Willacy counties. Exceptional (D4) drought conditions became scarcer and were confined to areas in Brooks, Starr, and Hidalgo counties.
