   MESOSCALE DISCUSSION 1383
   NWS STORM PREDICTION CENTER NORMAN OK
   0642 PM CDT MON JUL 14 2014

   AREAS AFFECTED...ERN/SRN ID...WRN MT...FAR NRN UT...WRN WY

   CONCERNING...SEVERE THUNDERSTORM WATCH 421...

   VALID 142342Z - 150045Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 421
   CONTINUES.

   SUMMARY...SVR THREAT ACROSS WW 421 CONTINUES...PARTICULARLY WRN MT.
   ADDITIONALLY...SOME ISOLATED SVR HAIL IS POSSIBLE ACROSS SRN
   ID...FAR WRN WY...AND FAR NRN UT BUT MARGINAL/ISOLATED NATURE OF THE
   THREAT WILL LIKELY PRECLUDE THE NEED FOR AN ADDITIONAL WATCH.

   DISCUSSION...TSTM ACTIVITY CONTINUES ACROSS MUCH OF THE WATCH AREA.
   WATER VAPOR IMAGERY SHOWS THE LEAD SHORTWAVE TROUGH HAS MOVED
   THROUGH THE AREA WITH A SECONDARY SHORTWAVE LIKELY THROUGH MUCH OF
   WRN ID. AS A RESULT...AN INCREASE IN TSTM COVERAGE IS POSSIBLE
   ACROSS WRN MT BUT STORM SEVERITY MAY BE TEMPERED BY COOLER SURFACE
   TEMPERATURES AND LIMITED INSTABILITY. 

   ADDITIONAL TSTM ACTIVITY IS POSSIBLE ACROSS SRN ID...FAR WRN
   WY...AND FAR NRN UT AS THE REGION IS GLANCED BY THE SECONDARY
   SHORTWAVE TROUGH. INSTABILITY AND SHEAR ACROSS THE AREA ARE
   SUPPORTIVE OF A FEW STRONG TO SVR STORMS CAPABLE OF HAIL AND GUSTY
   WINDS. SVR COVERAGE IS EXPECTED TO BE ISOLATED AND AN ADDITIONAL WW
   IS NOT ANTICIPATED.
