   Areas affected...portions of the eastern Texas Panhandle into
   northern Oklahoma and far southern Kansas

   Concerning...Tornado Watch 13...

   Valid 060334Z - 060500Z

   The severe weather threat for Tornado Watch 13 continues.

   SUMMARY...The severe threat continues across WW0013, with the
   primary threat for large hail and a tornado or two (perhaps strong).
   Two localized, short-term corridors of enhanced severe potential may
   accompany supercell thunderstorms currently tracking northeastward
   across portions of northern Oklahoma and the eastern Texas
   Panhandle.

   DISCUSSION...Regional VWP profiles depict strong low-level hodograph
   curvature, with over 300 m2/s2 0-500 m SRH, which will help support
   continued mesocyclone development and the potential for large hail
   and an isolated tornado or two with ongoing supercells across much
   of WW0013. The supercell thunderstorms currently tracking across
   portions of northern Oklahoma and the eastern Texas Panhandle are
   the primary concern for severe weather over the next 1-2 hours, with
   both supercells recently having confirmed tornadoes. In time, at
   least some decrease in severe potential is expected with the
   supercell in northern Oklahoma as it moves north/northeast and
   crosses the surface boundary into a more stable low-level air mass.
   MUCAPE values of 1500-2000 J/kg north of this boundary will allow
   the threat for large hail to persist for at least some time,
   however.
