   MESOSCALE DISCUSSION 0973
   NWS STORM PREDICTION CENTER NORMAN OK
   0338 PM CDT THU JUN 11 2015

   AREAS AFFECTED...PORTIONS OF E-CNTRL AND SERN CO

   CONCERNING...SEVERE THUNDERSTORM WATCH 284...

   VALID 112038Z - 112215Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 284
   CONTINUES.

   SUMMARY...A LARGE HAIL/DAMAGING WIND THREAT CONTINUES ACROSS WW 284.

   DISCUSSION...RADAR IMAGERY FROM KPUX SHOWS SEVERAL STRONG TO SEVERE
   THUNDERSTORMS ACROSS SERN CO...WITH ONE SUPERCELL OVER SRN LINCOLN
   COUNTY MOVING ESEWD WITH TIME. ADDITIONAL CONVECTION IS FORMING
   ACROSS THE HIGHER TERRAIN OF SERN CO WITH THE APPROACH OF A
   SHORTWAVE TROUGH OVER SRN CO/NRN NM. OTHER STORMS MAY FORM ALONG
   OUTFLOW BOUNDARIES GENERATED BY EARLIER CONVECTION. SFC TEMPERATURES
   HAVE WARMED INTO THE LOW TO MID 80S...WITH DEWPOINTS GENERALLY
   REMAINING IN THE MID TO UPPER 50S. MLCAPE OF 1000-1500 J/KG WILL
   CONTINUE TO SUPPORT A LARGE HAIL THREAT WITH THE STRONGER
   CORES...WHILE STEEP LOW-LEVEL LAPSE RATES MAY ALSO PROMOTE A
   DAMAGING DOWNDRAFT WIND THREAT. WITH MID-LEVEL FLOW STRENGTHENING
   WITH THE APPROACH OF THE SHORTWAVE TROUGH TO THE W...THE CONVECTION
   FIRING ALONG THE HIGHER TERRAIN OF SERN CO SHOULD ALSO BECOME SEVERE
   WITH TIME. ELY LOW-LEVEL FLOW VEERING TO SWLY ALOFT AND 0-1 KM SRH
   AROUND 150 M2/S2 PER THE KPUX VWP SUGGESTS AN ISOLATED TORNADO MAY
   ALSO BE POSSIBLE...ALTHOUGH WINDS IN THE 0-2 KM LAYER ARE RELATIVELY
   WEAK.
