   MESOSCALE DISCUSSION 0503
   NWS STORM PREDICTION CENTER NORMAN OK
   0429 PM CDT FRI APR 29 2016

   AREAS AFFECTED...PORTIONS OF FAR EASTERN MS AND NORTHERN/CENTRAL AL

   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 

   VALID 292129Z - 292300Z

   PROBABILITY OF WATCH ISSUANCE...20 PERCENT

   SUMMARY...A CLUSTER OF STORMS WILL CONTINUE TO POSE A THREAT FOR A
   FEW STRONG WIND GUSTS AND A LARGE HAIL REPORT OR TWO. HOWEVER...THE
   LIMITED NATURE OF THE THREAT PRECLUDES WATCH ISSUANCE.

   DISCUSSION...A QUASI-LINEAR COMPLEX OF STRONG TO OCCASIONALLY SEVERE
   STORMS CONTINUES EAST/SOUTHEASTWARD ACROSS FAR EASTERN MS AND
   NORTHERN/CENTRAL AL. THESE STORMS SHOULD GENERALLY FOLLOW AN
   INSTABILITY AXIS TO THEIR EAST/SOUTHEAST...WHERE PRIOR SFC HEATING
   HAS PROMOTED STEEPENED LOW-LEVEL LAPSE RATES AND AN ENVIRONMENT
   FAVORABLE FOR STRONG WIND GUSTS. ADDITIONALLY...ADVECTION OF
   WARM/MOIST AIR IS FAVORING PROPAGATION ALONG THE SOUTHERN END OF THE
   COMPLEX. MERGING COLD POOLS AND ANY EMBEDDED ROTATING ELEMENTS WILL
   FAVOR POCKETS OF GUSTY WINDS OVER THE NEXT FEW HOURS. HOWEVER...THE
   THREAT SHOULD SLOWLY DIMINISH AS BOUNDARY-LAYER STABILIZATION OCCURS
   AND CELLS BECOME MORE OUTFLOW-DOMINANT THIS EVENING.
