   NWS STORM PREDICTION CENTER NORMAN OK
   0539 PM CDT SUN MAY 08 2016

   AREAS AFFECTED...SOUTHWEST INTO NORTH TEXAS...

   CONCERNING...SEVERE THUNDERSTORM WATCH 148...

   VALID 082239Z - 090045Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 148
   CONTINUES.

   SUMMARY...THE SEVERE HAIL CONTINUES ACROSS WW 148... WITH AN
   INCREASING DAMAGING WIND THREAT EMERGING WITH ANY STORMS THAT CAN
   CONGEAL INTO LINES/LEWPS.

   DISCUSSION...THE SEVERE THREAT CONTINUES ACROSS WW 148.  RADAR
   MOSAIC IMAGERY INDICATES A CONTINUATION OF SCATTERED STRONG TO
   SEVERE THUNDERSTORMS ACROSS THE WATCH ATTM.  HAIL HAS BEEN THE
   PRIMARY THREAT WITH THESE STORMS GIVEN MODERATE INSTABILITY...STEEP
   LOW/MID LEVEL LAPSE RATES...AND 35-40 KNOT DEEP SHEAR.  LOW-LEVEL
   SHEAR HAS BEEN A BIT WEAK...LEADING TO THE OUTFLOW-DOMINATED NATURE
   OF THE STORMS /ESPECIALLY IN WESTERN AND CENTRAL PORTIONS OF THE
   WATCH/.  A FEW OF THE STORMS HAVE CONGEALED INTO SMALL
   LINES...ESPECIALLY IN SHACKLEFORD/CALLAHAN AND ALSO TOM GREEN/COKE
   COUNTIES.  OBSERVATIONAL AND HIGH-RES GUIDANCE SUGGESTS THAT THIS
   TREND SHOULD CONTINUE INTO THE EVENING...WITH A DAMAGING WIND THREAT
   INCREASING WITH TIME PARTICULARLY ACROSS EASTERN/NORTHEASTERN
   PORTIONS OF THE WATCH.
