   Concerning...Tornado Watch 146...

   Valid 272019Z - 272145Z

   The severe weather threat for Tornado Watch 146 continues.

   SUMMARY...Pair of potentially long-lived supercells within the
   southern portion of WW 146 may evolve with an intense tornado and
   very large hail threat.

   DISCUSSION...A potentially long-lived, slow-moving discrete
   supercell is centered over Knox County, TX. This supercell appears
   to be anchored along the far southern portion of the broader
   convective plume that extends north across OK/KS. With full
   insolation in the warm-moist sector inflow to its southeast, its
   plausible that a long-lived supercell will persist for the next 2-3
   hours. Amid MLCAPE of 3000 J/kg and mid 60s surface dew points to
   its southeast, a cyclic tornadic supercell could evolve beyond the
   very large hail threat with up to baseballs reported thus far. The
   supercell to its northeast in Wilbarger County, TX will also have
   potential to further intensify as it spreads towards and northwest
   of the Wichita Falls vicinity, given 0-1 km SRH of 100-200 m2/s2 per
   FDR VWP data.
