   Areas affected...southeastern Colorado...northeastern New
   Mexico...and the western Texas/Oklahoma Panhandles

   Concerning...Severe potential...Watch unlikely 

   Valid 212010Z - 212245Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Storms are expected to increase in coverage and intensity
   across the area this afternoon and evening posing an initial threat
   for hail and eventually evolving into a wind threat.  The severe
   threat appears too marginal and isolated to warrant a severe
   thunderstorm watch.

   DISCUSSION...Numerous thunderstorms have already initiated across
   the area ahead of a southward-moving midlevel shortwave trough. 
   While instability (MLCAPE around 1000 J/kg) and shear (effective
   bulk shear around 25 knots) are modest, initial multicell modes may
   support hail (0.75-1.25 in) and convective gusts (45-60 mph). 
   Eventually cold pool mergers are expected to lead to some degree of
   upscale growth, especially across northeastern New Mexico, where
   isolated severe gusts (55-65 mph) may be possible if an organized
   convective cluster develops.  A severe thunderstorm watch is
   unlikely given the isolated and marginal nature of the severe
   threat.
