   MESOSCALE DISCUSSION 1546
   NWS STORM PREDICTION CENTER NORMAN OK
   0310 PM CDT SUN JUL 26 2015

   AREAS AFFECTED...PORTIONS OF SERN IND...FAR NRN KY...AND SWRN INTO
   CNTRL/ERN OH

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 262010Z - 262215Z

   PROBABILITY OF WATCH ISSUANCE...5 PERCENT

   SUMMARY...A MARGINAL RISK FOR LARGE HAIL AND DAMAGING WINDS WILL
   EXIST THROUGH THE EARLY EVENING. WW ISSUANCE IS NOT EXPECTED AT THIS
   TIME.

   DISCUSSION...WITH THE APPROACH OF A LOW-AMPLITUDE SHORTWAVE TROUGH
   FROM THE UPPER MIDWEST...WIDELY SCATTERED THUNDERSTORMS HAVE
   DEVELOPED ACROSS SERN IND AND SWRN/CNTRL/ERN OH ALONG AND JUST AHEAD
   OF A NEARLY STALLED SFC COLD FRONT. COMPARED TO LOCATIONS FURTHER
   E...MID-LEVEL FLOW ASSOCIATED WITH THE UPPER TROUGH IS SLIGHTLY
   STRONGER...AND EFFECTIVE BULK SHEAR VALUES ACROSS THE MCD AREA ARE
   AROUND 30-35 KT PER RAP MESOANALYSIS. WITH MLCAPE AROUND 1000-2000
   J/KG...ONGOING MULTICELLULAR CONVECTION ACROSS THE MCD AREA SHOULD
   REMAIN CAPABLE OF PRODUCING MARGINALLY SEVERE HAIL AND ISOLATED
   INSTANCES OF STRONG/DAMAGING WINDS FOR THE NEXT SEVERAL HOURS. THE
   LACK OF STEEPER MID-LEVEL LAPSE RATES AND STRONGER EFFECTIVE BULK
   SHEAR VALUES SHOULD GENERALLY LIMIT A GREATER SEVERE WEATHER THREAT.
