Moisture surged westward onto the Caprock Friday night, setting the stage for an active Saturday afternoon and evening (23 May). As temperatures climbed into the 90s, scattered thunderstorms erupted across the South Plains region. Many of the storms produced small hail, and when they rotated the hail grew larger.

One particularly intense storm developed over southwestern Garza County, where it became anchored for a few hours. In addition to dropping large hail and torrential rain, this storm generated at least a couple of tornadoes (see the picture at the top of this page). Fortunately, the tornadoes remained over rural areas and did no known damage.

Another intense storm, this one racing northward into the southern-central Texas Panhandle, generated giant hail. Unfortunately, this storm did track over Silverton where baseball size hail (and larger) fell and inflicted significant damage.

The storms eventually grew into a complex that spread eastward across the Rolling Plains Saturday evening. Strong to severe wind gusts, small hail and heavy rain accompanied the complex. As the system shifted eastward, the setting sun illuminated the back side of the complex, creating a vividly picturesque sky.

Where the most intense storm of the day lingered, several inches of rain fell over much of the southwest half of Garza County. Rain totals of 3 to 5+ inches fell in a couple of hours. The West Texas Mesonet site in Post measured 3.42 inches, while southwest of town, the Graham site recorded a whopping 6.60 inches. 

 
24-hour radar-estimated and bias-corrected rain totals ending at 9 AM on Sunday (24 May).

Runoff from the torrential rainfall created flash flooding as water poured off the Caprock and funneled into the Double Mountain Fork of the Brazos River. The flood waters swept the pavement off FM 669 south of Post, as seen below.

The suddenly water-infused upper Brazos River poured into Lake Alan Henry, quickly raising the lake level over three feet. This propelled the lake above the conservation level for the first time since 2016.
