Very hot temperatures combined with a weak upper level disturbance, abundant moisture, and instability led to the development of thunderstorms on the afternoon of the fourth. These thunderstorms produced widespread wind damage and large hail. The hot and well mixed lower atmosphere and high-based nature of the thunderstorms provided ideal conditions for the generation of strong and severe wind gusts. Scattered thunderstorms initially developed in the Texas Panhandle along a surface trough and tracked to the south and southeast through the evening.
The first reports of severe weather were from Briscoe County with wind gusts up to 72 mph near Silverton. These initial thunderstorms then accelerated to the south forming a strong cold pool out ahead of the storms. Storms repeatedly formed along outflow boundaries in the central South Plains and quickly raced southward. One of these storms produced large hail up to two inches in diameter in Floyd County. This particular storm went on to produce wind damage in Ralls (Crosby County) and finally in Post (Garza County).  In far southwestern Garza County, this storm produced a wind gust to 94 mph near Graham. High precipitable water values contributed to flooding in Garza County along Texas State Highway 207 north of Post. Reports on social media showed the road had been damaged and impassable due to flooding.
Additional thunderstorms developed across the central South Plains and rushed southward from Hale into Lubbock and Lynn Counties. A large swath of severe winds initially affected a portion of Lubbock County and the city of Lubbock. The first severe wind gust was reported by the Automated Surface Observing System at Lubbock Preston Smith International Airport at 2020 CST. The Texas Tech University West Texas mesonet recorded additional severe wind gusts at Reese Center, Texas Tech University, and Slaton. These severe winds mostly affected the eastern portion of the city of Lubbock. In total, 50 power poles were downed along with a tree that fell onto and damaged a residence.
Thunderstorm outflow winds well ahead of the thunderstorms produced a severe wind gust to 58 mph at Amherst (Lamb County) at 1925 CST measured by the Texas Tech University West Texas mesonet.
