Thunderstorm Wind in Lynn County, Texas

A Texas Tech University West Texas mesonet near O'Donnell measured severe wind gusts from 1536 CST through 1547 CST. A peak wind gust of 83 mph was measured at 1543 CST.

A strong short wave trough moving through New Mexico on the afternoon of the second provided a large amount of large scale lift to the region allowing for widespread thunderstorm activity. Very steep mid-level lapse rates, strong surface heating, and ample low level moisture created a very unstable atmosphere by early afternoon. Initial thunderstorm development early in the afternoon was unable to become severe but once discrete storms morphed into a mesoscale convective system, storms became severe with severe wind gusts across the South Plains and Rolling Plains.
