   MESOSCALE DISCUSSION 0591
   NWS STORM PREDICTION CENTER NORMAN OK
   0639 PM CDT TUE MAY 10 2016

   AREAS AFFECTED...SOUTHWEST INTO NORTH TEXAS

   CONCERNING...SEVERE THUNDERSTORM WATCH 160...

   VALID 102339Z - 110115Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 160
   CONTINUES.

   SUMMARY...HAIL AND DAMAGING WIND THREAT CONTINUES ACROSS THE WATCH
   AREA...WITH SOME DEVELOPMENT EASTWARD TOWARD THE DFW METROPLEX AND
   CENTRAL TEXAS I-35 CORRIDOR POSSIBLE OVER THE NEXT 1-2 HOURS.

   DISCUSSION...CONTINUE WW 160.  SCATTERED THUNDERSTORMS NEAR MWL AND
   MNZ HAVE BEGUN TO CONGEAL AND PROPAGATE SLOWLY
   EASTWARD/SOUTHEASTWARD ALONG THE LEADING EDGES OF COLD POOLS
   ESTABLISHED FROM PREVIOUS CONVECTION.  OVER THE NEXT COUPLE OF
   HOURS...THESE STORMS ARE EXPECTED TO APPROACH AREAS NEAR/NORTHWEST
   OF THE DFW METROPLEX AND ALSO CENTRAL TEXAS...WITH HAIL AND DAMAGING
   WINDS LIKELY GIVEN THE VERY STRONG INSTABILITY /3500+ J/KG MUCAPE/
   IN PLACE ACROSS THE REGION.  

   FARTHER WEST...SCATTERED CONVECTION WILL CONTINUE TO PERCOLATE
   NEAR/SOUTH OF SJT...WITH LEFT-MOVING CELLS NOTED ALONG THE WESTERN
   FRINGES OF THE WW.  ALTHOUGH INSTABILITY IS SLIGHTLY LOWER IN THIS
   REGION DUE TO LESSER BOUNDARY-LAYER MOISTURE CONTENT...HAIL AND
   DAMAGING WIND GUSTS ARE POSSIBLE WITH THE STRONGER STORMS.  THIS
   THREAT MAY DIMINISH SOME AFTER DARK AS NOCTURNAL BOUNDARY LAYER
   COOLING REDUCES SURFACE-BASED INSTABILITY.
