   MESOSCALE DISCUSSION 0944
   NWS STORM PREDICTION CENTER NORMAN OK
   0324 PM CDT MON JUN 08 2015

   AREAS AFFECTED...TN VALLEY TO CNTRL APPALACHIANS

   CONCERNING...SEVERE THUNDERSTORM WATCH 275...277...

   VALID 082024Z - 082200Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   275...277...CONTINUES.

   SUMMARY...ISOLATED DAMAGING WINDS AND MARGINAL HAIL RISKS CONTINUE
   WITHIN A BROAD SWATH OF NUMEROUS CONVECTIVE CLUSTERS ACROSS WW/S
   275/277. THESE RISKS MAY ALSO EXTEND BOTH SOUTH AND NORTH OF CURRENT
   WW/S. ADDITIONAL WW ISSUANCE/S SEEM UNLIKELY BUT LOCAL WFO
   EXTENSIONS ARE POSSIBLE.

   DISCUSSION...THE MOST INTENSE TSTM CLUSTER WITHIN WW/S 275/277 OVER
   THE NASHVILLE METRO AREA. WITH A SMALL POCKET OF YET TO BE
   OVERTURNED MODERATELY UNSTABLE AIR MASS AND EFFECTIVE SHEAR NEAR
   30-KT...THE RISK FOR DAMAGING WINDS AND MARGINALLY SEVERE HAIL
   SHOULD BE RELATIVELY GREATEST HERE THROUGH ABOUT 22Z.
   ELSEWHERE...EXTENSIVE OVERTURNING IS ONGOING WITH A BROKEN LINE OF
   STORMS ACROSS THE CNTRL APPALACHIANS TO CUMBERLAND PLATEAU AS WELL
   AS SCATTERED DEVELOPMENT FROM THE CNTRL OH VALLEY TO THE MID-SOUTH.
   LARGELY MODERATE DEEP-LAYER SHEAR SHOULD SUPPORT CONTINUED CLUSTERS
   CAPABLE OF STRONG WIND GUSTS AND MAINLY ISOLATED DAMAGE.
