   MESOSCALE DISCUSSION 0579
   NWS STORM PREDICTION CENTER NORMAN OK
   0239 AM CDT SUN MAY 10 2015

   AREAS AFFECTED...N-CNTRL AR

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 100739Z - 100845Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...ISOLD STRONG TO LOCALLY SEVERE WIND GUSTS ARE POSSIBLE FOR
   THE NEXT FEW HOURS.  A SEVERE THUNDERSTORM WATCH APPEARS UNNECESSARY
   AT THIS TIME BUT TRENDS WILL CONTINUE TO BE MONITORED.

   DISCUSSION...RADAR MOSAIC SHOWS A WEST-EAST ORIENTED CLUSTER OF
   STORMS MOVING EWD ACROSS THE GREATER FSM AREA EWD INTO N-CNTRL AR. 
   THE KFSM ASOS RECORDED A 47 KT WIND GUST WITH PASSAGE OF A BOWING
   SEGMENT AROUND 07Z.  ALTHOUGH SOME NOCTURNAL BOUNDARY LAYER
   DECOUPLING HAS LIKELY OCCURRED...MOIST LOW LEVELS CHARACTERIZED BY
   MID 60S DEWPOINTS ARE CONTRIBUTING TO MODERATE BUOYANCY ACCORDING TO
   OBJECTIVE ANALYSIS /1000-1500 J PER KG MUCAPE/.  THE KLZK VAD SHOWS
   A STRONG AND VEERING LOW-LEVEL HODOGRAPH WHICH SHOULD SUPPORT STORM
   ORGANIZATION.  AS A RESULT...A FEW STRONG TO LOCALLY SEVERE WIND
   GUSTS MAY ACCOMPANY SEVERAL OF THE STRONGER STORMS OVER THE NEXT FEW
   HOURS AS THIS ACTIVITY MOVES GENERALLY EWD ACROSS N-CNTRL AR.  GIVEN
   THE ANTICIPATED COVERAGE AND MARGINAL THREAT FOR SEVERE WIND
   GUSTS...A SEVERE THUNDERSTORM WATCH WILL PROBABLY NOT BE NEEDED.
