   NWS STORM PREDICTION CENTER NORMAN OK
   0952 PM CDT WED MAY 11 2016

   AREAS AFFECTED...PORTIONS OF N TX

   CONCERNING...SEVERE THUNDERSTORM WATCH 170...

   VALID 120252Z - 120345Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 170
   CONTINUES.

   SUMMARY...THE RISK FOR SVR TSTMS WITH LARGE HAIL AND DMGG WINDS
   CONTINUES ACROSS WW 170.

   DISCUSSION...TSTM CLUSTERS FROM MINERAL WELLS TO COLEMAN TX CONTINUE
   SPREADING EWD/SWD WITH CONVECTIVE BACKBUILDING TAKING PLACE UPSTREAM
   ACROSS THE LOW ROLLING PLAINS. MODEST INCREASES IN MLCINH E OF THE
   AFOREMENTIONED CONVECTION MAY MARGINALIZE THE SVR RISK ACROSS PARTS
   OF N-CNTRL TX...THOUGH AMPLE BUOYANCY SAMPLED BY THE 00Z FWD RAOB
   SUGGESTS SVR HAIL/WIND MAY PERSIST WITH THIS ACTIVITY TOWARD W SIDES
   OF THE DFW METROPLEX AND VICINITY. LARGE-SCALE ASCENT AHEAD OF A
   MID-LEVEL TROUGH WILL SUPPORT CONVECTIVE BACKBUILDING INTO THE
   OVERNIGHT HOURS ACROSS PARTS OF NW TX. WW 170 IS PRESENTLY SCHEDULED
   TO EXPIRE AT 04Z. HOWEVER...SOME SVR RISK MAY CONTINUE LATER INTO
   THE OVERNIGHT HOURS AS MODERATELY TO STRONGLY UNSTABLE INFLOW EXISTS
   AMIDST MODERATE DEEP SHEAR...POTENTIALLY WARRANTING EXTENSION OF THE
   WW IN TIME OR A NEW WW.
