   Areas affected...Salt Lake Vicinity

   Concerning...Severe potential...Watch unlikely 

   Valid 111830Z - 112030Z

   Probability of Watch Issuance...20 percent

   SUMMARY...Severe wind gusts will be possible this afternoon with
   high-based showers and embedded thunderstorms.

   DISCUSSION...With temperatures rising into the low/mid 80s F in the
   vicinity of Salt Lake, high-based showers and isolated thunderstorms
   have deepened over the last hour. A few of these storms have
   produced 58-63 mph measured gusts in Tooele/Salt Lake Counties.
   While low-level wind fields are not overly strong, the 9.2 C/km
   700-500 mb lapse rate observed in this mornings 12Z SLC sounding,
   coupled with steep low-level lapse rates and high surface dewpoint
   depressions, will continue to support strong diabatically driven
   downdrafts. Severe wind gusts will remain possible through the
   afternoon in association with this weak, disorganized convection.
