   Areas affected...portions of western and central Texas

   Concerning...Tornado Watch 55...

   Valid 190628Z - 190830Z

   The severe weather threat for Tornado Watch 55 continues.

   SUMMARY...Severe/isolated tornado risk continues across the WW area,
   including a well-developed supercell now crossing Taylor County.

   DISCUSSION...Latest radar loop shows a strongly rotating storm
   crossing northern Taylor County at this time, within northern
   portions of WW #55.  KDYX WSR-88D has depicted rotational velocities
   near 50 kt with this cell at times, along with a CC min/TDS near the
   Nolan/Taylor County border just after 06Z.  With the KDYX VWP
   showing substantial veering/increasing of the flow field with height
   through the lowest 2km, and a thermodynamic environment featuring
   1500 J/kg mixed-layer CAPE, expect this risk to continue as storms
   spread quickly east-northeastward at 45 kt.

   Meanwhile farther south, storms continue to increase either side of
   the Rio Grande, just west/northwest of Del Rio, where a similarly
   favorable kinematic and thermodynamic environment exists.  A such,
   severe risk appears likely to increase over southern and central
   portions of the watch over the next 1-2 hours.
