		Brief Description: EVENT NARRATIVE: At 12:15 pm CST, members of the TWISTEX research group confirmed the formation of a tornado approximately 6.5 miles south of Notrees. This tornado progressed northeastward around 20 mph, first causing damage to power poles around from 12:16 to 12:17 pm CST. As it continued to track to the northeast, the tornado caused significant damage to oil equipment from 12:19 to 12:22 pm CST. Two type 320 pump jacks, each weighing 71,000 pounds including the concrete base, were blown over. The tornado then began to weaken at 12:27 pm CST, and dissipated at 12:28 pm CST approximately 2 miles southeast of Notrees, TX. EPISODE NARRATIVE: During the late morning hours, an upper level disturbance slowly progressed over the area. At the surface, abundant low level moisture was available due to southeasterly to easterly winds. A nearly stationary frontal boundary across the Permian basin provided a focus for rapid thunderstorm development. Several supercell thunderstorms resulted in widespread severe weather in the form of tornadoes, flash flooding and large hail across the Texas Permian Basin. The supercell thunderstorms eventually diminished during the late evening hours across the southern Permian Basin.
