   Areas affected...portions of Southwest Oklahoma and
   Western/Northwest Texas

   Concerning...Tornado Watch 100...

   Valid 112029Z - 112130Z

   The severe weather threat for Tornado Watch 100 continues.

   SUMMARY...The severe thunderstorm threat continues across WW #100.
   While the primary threat remains large to very large hail, a few
   tornadoes are also possible this afternoon/evening.

   DISCUSSION...At 2020Z radar data suggested two severe thunderstorms
   ongoing in and near WW #100. One of these storms is located across
   Southwest Oklahoma and has a history of producing large hail. While
   MRMS data continues to exhibit large hail characteristics with this
   storm (e.g., MESH > 1 inch), the environment to the east is a bit
   less favorable, which may promote gradual storm weakening over the
   next hour or so. Despite this, large hail will remain possible with
   this storm as it moves east out of the Watch #100. Another severe
   storm is moving into portions of northwest Texas (Stonewall County)
   and has developed supercell characteristics over the last 30-45
   minutes. Large hail is likely with this thunderstorm as it moves
   northeast. 

   Otherwise, scattered thunderstorms should continue to develop across
   much of WW #100 through the remainder of the afternoon. MLCAPE
   values near 2500 J/kg coupled with effective bulk shear near 40-50
   knots will foster supercell thunderstorms with scattered large hail
   potential (some 2+ inches). While large hail should be the primary
   threat, the tornado potential is expected to increase through the
   afternoon and into the evening as low-level moistening continues and
   shear increases.
