   Areas affected...central and eastern Utah into western Colorado

   Concerning...Severe potential...Watch possible 

   Valid 271843Z - 272115Z

   Probability of Watch Issuance...60 percent

   SUMMARY...Storms will continue to increase in coverage from Utah
   into western Colorado, with areas of severe wind or hail possibly
   developing.

   DISCUSSION...Visible satellite and radar shows storms already
   developing over the higher terrain, with occasional signs of brief
   hail over southwest UT. Precipitable water values around around
   1.00" over the entire region, which when combined with heating is
   resulting in over 1000 J/kg MLCAPE.

   While the main shortwave trough will move north of the area,
   midlevel westerlies will increase to over 40 kt, elongating
   hodographs. Combined with steepening lapse rates, this should prove
   favorable for cells or small bows capable of damaging winds and
   marginal hail.

   As remaining inhibition is erased this afternoon, storms are likely
   to proceed across the lower elevations and sustain. As such, a watch
   is being considered.
