   Areas affected...Northeast OK into southeast KS

   Concerning...Tornado Watch 189...

   Valid 070235Z - 070330Z

   The severe weather threat for Tornado Watch 189 continues.

   SUMMARY...A discrete supercell will pose a strong/intense tornado
   threat, while a growing QLCS to the west may pose an increasing
   threat for severe wind gusts and line-embedded tornadoes with time.

   DISCUSSION...A discrete supercell has recently intensified across
   northeast OK, and may be producing a strong to intense tornado,
   based on rotational velocity, environment, and TDS characteristics.
   Strong instability and intense low-level shear/SRH (with 0-1 km SRH
   increasing above 400 m2/s2 on the KINX VWP) will continue to support
   intense tornado potential with this cell as it moves northeastward. 

   Farther north and west, a growing QLCS will pose an increasing
   threat of severe wind gusts and line-embedded tornadoes as it moves
   eastward. This QLCS will eventually tend to absorb the ongoing
   tornadic cell and other discrete cells that may develop ahead of the
   line, which would potentially increase the tornado threat in the
   area of the QLCS where these mergers occur.
