MESOSCALE DISCUSSION 0831
   NWS STORM PREDICTION CENTER NORMAN OK
   0657 PM CDT THU MAY 28 2015

   AREAS AFFECTED...MUCH OF WRN TX INTO THE HILL COUNTRY

   CONCERNING...TORNADO WATCH 234...

   VALID 282357Z - 290200Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 234 CONTINUES.

   SUMMARY...NUMEROUS STORMS ARE EXPECTED TO PERSIST INTO CNTRL TX WITH
   MAINLY A DAMAGING WIND AND HAIL THREAT. A NEW WATCH MAY BE REQUIRED
   ACROSS PORTIONS OF CNTRL TX INTO THE RIO GRANDE VALLEY.

   DISCUSSION...STORMS HAVE MERGED INTO MULTIPLE LINES ACROSS NRN INTO
   SWRN TX WITH A LOT OF OUTFLOW PRODUCTION. AS A RESULT...THE TORNADO
   THREAT HAS DECREASED.

   AHEAD OF THE MERGING LINES...A VERY MOIST AND UNSTABLE AIR MASS
   REMAINS...AND WILL SUPPORT CONTINUED ROBUST STORM DEVELOPMENT INTO
   MUCH OF CNTRL AND SRN TX THIS EVENING. THE HIGH PW ENVIRONMENT AS
   WELL AS LINEAR STORM MODE SUGGEST THAT DAMAGING WINDS WILL BE THE
   PRIMARY THREAT...BUT A FEW CORES WILL ALSO CONTAIN HAIL. DUE TO THE
   MOIST AIR MASS...CAPPING IS EXPECTED TO BE NEGLIGIBLE.
