   MESOSCALE DISCUSSION 0904
   NWS STORM PREDICTION CENTER NORMAN OK
   0659 PM CDT FRI JUN 05 2015

   AREAS AFFECTED...NWRN KS / E-CNTRL CO

   CONCERNING...TORNADO WATCH 260...

   VALID 052359Z - 060100Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 260 CONTINUES.

   SUMMARY...THE NEAR-STORM ENVIRONMENT FOR A STRONG TORNADO IS
   BECOMING MORE FAVORABLE AS LOW-LEVEL SHEAR INCREASES MARKEDLY.  A
   COMPLICATING FACTOR WILL LIKELY BE CONVECTIVE MODE.

   DISCUSSION...GLD VAD DATA HAS SHOWN A SUBSTANTIAL INCREASE IN THE
   SIZE OF THE HODOGRAPH OVER THE PAST HOUR AS 0-3 KM SRH HAS
   STRENGTHENED FROM 200 M2/S2 TO NEAR 400 M2/S2 WHEN ACCOUNTING FOR
   THE KIT CARSON COUNTY TORNADIC SUPERCELL MOTION.  THE BLOSSOMING OF
   ADDITIONAL STORMS NEAR ITR WILL PROBABLY COMPLICATE AND POSSIBLY BE
   DETRIMENTAL IN THE LONG-TERM FOR TORNADO POTENTIAL WITH THE
   ESTABLISHED SUPERCELLS.  HOWEVER...IN THE NEAR TERM...THE LOWER 60S
   DEWPOINTS INDICATIVE OF A MOIST BOUNDARY LAYER AND SIZABLE SRH WILL
   LEND THE POSSIBILITY FOR A STRONG TORNADO OR TWO OVER THE NEXT HOUR
   OR SO.
