Severe thunderstorms developed and moved across the western and central Texas Panhandle during the mid afternoon through the evening and late night hours producing extreme amounts of hail as well as strong thunderstorm wind gusts. The very heavy rainfall from the thunderstorms also resulted in some flash flooding problems. The strong thunderstorm wind gusts resulted in downed tree limbs and the flash flooding and hail accumulations caused stalled vehicles and closed highways. There were no reports of injuries or fatalities.

A severe and slow moving thunderstorm over northern Potter County, about 3 miles south of Masterson, brought a tremendous amount of hail and very heavy rain across U.S. Highway 287.  The National Weather Service doppler radar estimated that 5-6 inches of rain fell in a very small area in northern Potter County, approximately 26 miles north of Amarillo.  Most of this rain fell in one to two hours during the late afternoon.  Large hail, up to the size of golfballs, fell in addition to the heavy rain.  The runoff from the heavy rain pushed the hail into 3-4 foot drifts across Highway 287.  The highway was closed for over 12 hours due to the water flooding the roadway and the hail drifts.  The runoff from the heavy rain also caused a normally dry creek to rise about 15 feet, approximately 23 miles north of Amarillo.  The creek was reported to have risen to the bottom side of a bridge on Highway 287.  A storm survey nearly 20 hours after the event revealed hail was still piled up to 3 feet in places and remained as large as ping pong balls.  At the bridge site, severe erosion of the bankment just downstream of the bridge was noted.
