   Areas affected...Portions of southwestern Texas

   Concerning...Tornado Watch 147...

   Valid 192121Z - 192215Z

   The severe weather threat for Tornado Watch 147 continues.

   SUMMARY...The severe threat continues across Severe Thunderstorm
   Watch 147. The highest tornado threat exists with supercells
   interacting with a boundary.

   DISCUSSION...Multiple supercells have become sustained across
   portions of southwestern Texas, with the lead supercell having a
   history of producing a tornado while interacting with a mesoscale
   baroclinic boundary. While severe gusts and hail will remain a
   concern with these storms over the next several hours, additional
   tornadoes remain possible with any of these storms if their updrafts
   can anchor to the boundary and effectively ingest locally higher
   SRH.
