Thunderstorm Wind — Lexington, South Carolina

2025-07-11 · near Gaston Lex Co Arpt, Lexington, South Carolina

Event narrative

Lexington County EM reported a couple of trees down near Swansea blocking the roadway. Time estimated by radar.

Wider weather episode

An upper trough in the region the past couple days began its exit on 7/11, but some weak shortwave energy coupled with weak surface troughing led to scattered convective development during the afternoon and evening. MLCAPE in excess of 2500 J/kg developed by the late afternoon, though deep layer shear was under 20 kts. Steeper low level lapse rates brought high DCAPE values and thus this environment brought two severe thunderstorms, one in Lexington County and one in Orangeburg County, both causing tree damage.
