   MESOSCALE DISCUSSION 0610
   NWS STORM PREDICTION CENTER NORMAN OK
   0144 PM CDT MON MAY 11 2015

   AREAS AFFECTED...SRN MS...SERN LA

   CONCERNING...SEVERE POTENTIAL...WATCH POSSIBLE 

   VALID 111844Z - 112045Z

   PROBABILITY OF WATCH ISSUANCE...40 PERCENT

   SUMMARY...STRONG STORMS WILL PERSIST THIS AFTERNOON WITH MARGINAL
   WIND AND HAIL AS WELL AS A BRIEF/WEAK TORNADO POSSIBLE.

   DISCUSSION...STRONG STORMS CONTINUE TO FORM ALONG A LINE FROM SWRN
   MS INTO ERN LA NEAR THE ADVANCING OUTFLOW BOUNDARY WITH WEAK
   ROTATION NOTED IN SEVERAL CELLS. THIS IS LIKELY DUE TO A COMBINATION
   OF ENHANCED VORTICITY NEAR THE OUTFLOW BOUNDARY COMBINED WITH ROBUST
   UPDRAFT STRENGTH. STORMS THAT CAN REMAIN ALONG THE BOUNDARY...EITHER
   BY WAY OF PROPAGATION OR A SLOWING OF A PORTION OF THE
   BOUNDARY...MAY BECOME CAPABLE OF A BRIEF/WEAK TORNADO. HOWEVER...THE
   THREAT AREA IS SMALL IN BOTH SPACE AND TIME.
