   MESOSCALE DISCUSSION 0635
   NWS STORM PREDICTION CENTER NORMAN OK
   0723 PM CDT MON MAY 16 2016

   AREAS AFFECTED...N-CNTRL TX PANHANDLE INTO WRN OK

   CONCERNING...SEVERE THUNDERSTORM WATCH 176...177...

   VALID 170023Z - 170130Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   176...177...CONTINUES.

   SUMMARY...A STORM CLUSTER OVER THE NRN TX PANHANDLE WILL CONTINUE TO
   MOVE ESEWD AND AFFECT PORTIONS OF THE NERN TX PANHANDLE AND
   EVENTUALLY MOVE INTO WRN OK.  A NEW SEVERE THUNDERSTORM WATCH WILL
   LIKELY BE NEEDED BY 0130-0200Z FOR PORTIONS OF WRN OK.

   DISCUSSION...RADAR MOSAIC SHOWS A BAND OF STORMS WITH A FEW
   SUPERCELLS ON THE SWRN PORTION OF THE CLUSTER OVER THE NRN TX
   PANHANDLE.  SURFACE OBSERVATIONS SHOW TEMPS HAVE RISEN INTO THE
   LOWER 70S WITH DEWPOINTS AROUND 60 DEG F.  WHILE LOW-LEVEL SHEAR HAS
   INCREASED THE PAST 1-2 HOURS PER KAMA VAD DATA...UPSCALE GROWTH INTO
   A LESS-ORGANIZED CONVECTIVE MODE /QUASI-DISCRETE TO LINEAR CLUSTER/
   APPEARS UNDERWAY.  THE 00Z AMA RAOB SHOWED VERY STEEP H7-H5 LAPSE
   RATES /8.5 DEG C PER KM/ WITH SELY LOW-LEVEL WINDS VEERING TO AROUND
   50 KT AT H5.  AS SUCH...THE NEAR-STORM ENVIRONMENT WILL REMAIN
   FAVORABLE FOR ORGANIZED SEVERE STORMS.

   EXPECTING AN UPSCALE GROWTH EVOLUTION TO OCCUR DURING THE NEXT 1-2
   HOURS AS STORMS MOVE DOWNSTREAM.  FOR ANY STORMS MAINTAINING A
   CELLULAR STRUCTURE...LARGE HAIL WILL CONTINUE TO BE A THREAT IN
   ADDITION TO PERHAPS A TORNADO.  IF STORMS GROW INTO A WELL-CONNECTED
   BAND OF CELLULAR STORMS...THE PREDOMINANT THREAT THAT MAY DEVELOP
   WITH TIME COULD BE MORE WIDESPREAD SEVERE GUST POTENTIAL---BEGINNING
   IN THE ERN PANHANDLE AND MOVING INTO WRN OK.  SEVERE GUSTS
   POTENTIALLY EXCEEDING 65 KT MAY OCCURRED IF THIS SCENARIO UNFOLDS.
