   MESOSCALE DISCUSSION 0903
   NWS STORM PREDICTION CENTER NORMAN OK
   1233 PM CDT FRI MAY 31 2013

   AREAS AFFECTED...FAR SE MI...WRN OH...FAR SE IND...CNTRL/ERN KY...N
   CNTRL TN

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 311733Z - 311900Z

   CORRECTED FOR AFFECTED AREA

   PROBABILITY OF WATCH ISSUANCE...40 PERCENT

   SUMMARY...THUNDERSTORM COVERAGE WILL INCREASE THROUGH THE AFTERNOON.
   LOOSELY ORGANIZED STRONG TO SEVERE STORM CLUSTERS WILL BE CAPABLE OF
   PRODUCING STRONG WINDS AND MARGINALLY SEVERE HAIL.

   DISCUSSION...SCATTERED THUNDERSTORMS WERE DEVELOPING IN AREA OF
   INCREASING ASCENT AHEAD OF UPPER SHORTWAVE IMPULSE MOVING ACROSS THE
   MID-MS VALLEY EARLY THIS AFTERNOON. POCKETS OF STRONGER HEATING
   ACROSS SE MI/WRN OHIO INTO PARTS OF CNTRL AND ERN KY HAS ALLOWED FOR
   WEAK DESTABILIZATION WITH SBCAPE VALUES AROUND 1000 J/KG. BULK SHEAR
   VALUES AROUND 20-40 KTS SHOULD LEAD TO AT LEAST SOME ORGANIZED
   CLUSTERS/LINE SEGMENTS. THE BEST LOCATIONS FOR THIS TO OCCUR WOULD
   BE ACROSS FAR SW MI /WHERE STORMS ARE CURRENTLY ONGOING/ INTO PARTS
   OF IND AND OHIO WHERE DEEP LAYER SHEAR IS A BIT STRONGER THAN
   FURTHER SOUTH INTO KY/TN. HOWEVER...A REMNANT MCV EVIDENT IN
   SATELLITE IMAGERY MOVING ACROSS THE LOWER OHIO VALLEY MAY SERVE TO
   FOCUS STRONGER THUNDERSTORM DEVELOPMENT THIS AFTERNOON ACROSS KY
   DESPITE WEAKER DEEP LAYER SHEAR. STRONG WINDS AND MARGINALLY SEVERE
   HAIL WILL BE THE MAIN THREATS WITH ANY ORGANIZED STORMS THAT CAN
   DEVELOP TODAY. TRENDS WILL BE MONITORED FOR POSSIBLE WW ISSUANCE.
