   Concerning...Severe Thunderstorm Watch 441...

   The severe weather threat for Severe Thunderstorm Watch 441

   SUMMARY...Large to very-large hail and isolated strong/severe winds
   are most likely in parts of southeast Utah and adjacent western

   DISCUSSION...Though the mid-level trough is continuing to lose
   amplitude with time, strong mid-level winds should continue to
   persist in the eastern Great Basin. At present, the most undisturbed
   airmass is roughly within southeastern Utah into adjacent far
   western Colorado. A supercell in San Juan County remains the
   strongest storm in the area and will be most capable of producing 2+
   inch hail in the short term. Other storms in the Emery/Grand
   Counties vicinity may intensify and pose a threat for large hail as
   well. As storms move farther into the western slope, buoyancy will
   be decreased and storm intensity should wane. Elsewhere in WW 441,
   cloud cover/outflow has had some impact and storms have not been as
   intense in the last hour. However, isolated large hail and
   strong/severe winds could occur if any of that peripheral activity
