Scattered thunderstorms developed over a large portion of the Southern Plains during the evening hours of the 19th. This activity evolved into a derecho, or long-lived linear convective complex resulting in extreme winds, that rapidly propagated southeastward over the eastern Texas Panhandle, southwestern Oklahoma, and western north Texas.
In addition to damaging thunderstorm winds, Texas Tech University West Texas Mesonet data depicted a well-defined mesoscale high that developed in the wake of the storms. This feature contributed to wind gusts measured as high as 89 mph in Memphis (Hall County). Structural damage was limited, and no injuries were reported. Also, several reports were received of cotton and wheat crop damage in associated with large hail over the western South Plains.
