   Concerning...Severe Thunderstorm Watch 470...

   Valid 300138Z - 300245Z

   The severe weather threat for Severe Thunderstorm Watch 470
   continues.

   SUMMARY...Corridor of enhanced damaging wind potential is emerging
   across the eastern Texas Panhandle.

   DISCUSSION...Recent scans on KAMA radar show strong velocity values
   (e.g., exceeding 80 kt at 300 ft AGL) with a storm that developed
   northwest of AMA and is tracking through northern and northeast
   sides of the metro area. This storm has produced estimated 60-70 mph
   winds and 1.5-2 inch hail. The 00z AMA sounding indicates nearly
   1200 J/kg of DCAPE and steep low-level lapse rates, supporting the
   damaging wind potential, in addition to ambient 35 kt of effective
   shear colocated with a compact mid-level short-wave trough to
   support persistent storm organization. Thus, as this storm continues
   eastward, upscale growth appears possible with a threat for damaging
   winds.
