   Areas affected...Southern High Plains

   Concerning...Severe potential...Watch unlikely 

   Valid 120014Z - 120215Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Isolated severe thunderstorms may produce large hail and
   gusty winds this evening. Severe thunderstorm watch is not currently

   DISCUSSION...Upper trough over the Four Corners region is shifting

   where surface temperatures are only in the upper 50s/lower 60s.
   Latest radar data suggests slow-moving supercells will gradually
   shift east across the instability axis and should weaken as this
