Scattered thunderstorms initially developed over the western South Plains on the afternoon of the 24th under a very unstable atmosphere. Relatively weak atmospheric flow for late May kept most of these storms from becoming severe. These storms produced mostly heavy rainfall but were also able to generate a few severe hail and wind reports. Most hail reports were only up to the size of quarters but one report of golf balls was reported in Hockley County near Whitharral. More notably, heavy rain caused flash flooding in the city of Lubbock and along the Double Mountain Fork of the Brazos in Lubbock County. Heavy rain over the northeastern portion of the city of Lubbock flowed through Mackenzie Park into the Double Mountain Fork of the Brazos. This water made its way downstream into Buffalo Springs Lake flowing over Farm to Market Road 835 west of the lake. The road was shut down on the 25th due to water flowing over the roadway making it impassable.

Thunderstorms producing heavy rainfall repeatedly developed and moved over the northeastern portion of the city of Lubbock late on the 24th particularly around the intersection of Interstate-27 and North Loop 289. Early in the morning of the 25th, Lubbock police reported numerous vehicles had become stranded on area roadways. At this point, many roads were closed off by law enforcement due to flooding. Water eventually flowed into the Double Mountain Fork of the Brazos through Mackenzie Park in Lubbock (Lubbock County). This flow of water inundated Joyland Amusement Park shutting down the park until early June. Farther downstream, water flowed over Farm to Market Road 835 west of Buffalo Springs Lake. The road was closed due to the roadway becoming impassable.
