   MESOSCALE DISCUSSION 0230
   NWS STORM PREDICTION CENTER NORMAN OK
   0128 PM CDT SUN MAR 30 2014

   AREAS AFFECTED...UT...SWRN WY...NWRN CO

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 301828Z - 302030Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...SCATTERED SHOWERS/STORMS MAY AUGMENT STRONG GRADIENT WINDS
   TO YIELD ISOLATED SEVERE WIND GUSTS THROUGH THE AFTERNOON.

   DISCUSSION...AN INCREASE IN CONVECTIVE DEVELOPMENT HAS OCCURRED IN
   THE PAST HOUR ALONG/AHEAD OF A COLD FRONT PUSHING EWD ACROSS THE ERN
   GREAT BASIN. WITH LIMITED MOISTURE...MODIFIED 12Z RAOBS/RAP FORECAST
   SOUNDINGS SUGGEST SBCAPE IS QUITE MEAGER AOB 250 J/KG. EVEN
   SO...STEEP LAPSE RATES IN CONJUNCTION WITH ROBUST-FORCED ASCENT
   THROUGH MID-LEVEL DCVA AHEAD OF THE NV SHORTWAVE TROUGH WILL BE
   SUFFICIENT FOR MAINTAINING SCATTERED CONVECTION THROUGH THE
   AFTERNOON. UPDRAFT STRENGTH WILL LIKELY BE WEAK...BUT INTENSE
   GRADIENT LOW-LEVEL WINDS ARE PREVALENT AHEAD OF THE COLD
   FRONT...SAMPLED FROM 50-60 KT AOB 2 KM AGL IN KICX/KGJX VWP DATA.
   THIS SUGGESTS THAT EVEN LITTLE AUGMENTATION VIA CONVECTIVE
   DOWNDRAFTS COULD PRODUCE SEVERE WIND GUSTS COINCIDENT WITH SPORADIC
   LIGHTNING.
