   Concerning...Tornado Watch 189...

   Valid 070359Z - 070530Z

   The severe weather threat for Tornado Watch 189 continues.

   SUMMARY...Supercells capable of all severe hazards will spread
   eastward into the early overnight hours. Strong tornadoes remain
   possible. WW 189 will be extended in time.

   DISCUSSION...Storms have recently developed in the vicinity of the
   Pacific cold front in southwest OK. Downstream, the 03Z OUN sounding
   indicates a very favorable environment remains in place across
   central OK, with strong buoyancy, effective shear of 60+ kt, and 0-1
   km SRH of greater than 300 m2/s2. A threat for supercells will move
   quickly eastward into the early overnight hours, with a threat of
   all severe hazards. Strong to intense tornadoes remain possible if
   discrete supercells can be maintained. WW 189 will be extended in
   time to cover this threat.
