   MESOSCALE DISCUSSION 0752
   NWS STORM PREDICTION CENTER NORMAN OK
   0916 PM CDT SUN MAY 24 2015

   AREAS AFFECTED...PORTIONS OF SWRN KS

   CONCERNING...TORNADO WATCH 206...

   VALID 250216Z - 250345Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 206 CONTINUES.

   SUMMARY...THE THREAT FOR LARGE HAIL AND A FEW DAMAGING WIND
   GUSTS...AS WELL AS A TORNADO OR TWO...CONTINUES PRIMARILY ACROSS FAR
   SRN PORTIONS OF WW 206.

   DISCUSSION...THE 02Z WSR-88D MOSAIC EXHIBITS A PAIR OF SUPERCELLS
   OVER SEWARD CO KS. MEANWHILE...A BAND OF CONVECTION FROM WICHITA CO
   TO STANTON CO /WITH AN EMBEDDED MESOVORTEX ON THE NRN END/ CONTINUES
   TO PROGRESS EWD. ADDITIONALLY...AN EMBEDDED SUPERCELL APPEARS TO
   HAVE EVOLVED WITHIN THE SRN END OF THIS LINE. NRN PORTIONS OF THIS
   LINEAR SYSTEM HAVE WEAKENED OVER THE LAST HOUR...BUT THE
   AFOREMENTIONED CELLS TO THE SOUTHEAST /AS WELL AS THE TAIL-END
   SUPERCELL/ ARE CONTINUING TO SUPPORT A THREAT FOR LARGE
   HAIL...DAMAGING WINDS...AND A COUPLE OF TORNADOES. WHILE NOCTURNAL
   COOLING HAS COMMENCED AND THE 00Z DDC RAOB SAMPLED SOME MLCIN AROUND
   750-700 MB /INDICATIVE OF A MORE HOSTILE THERMODYNAMIC ENVIRONMENT
   TO THE EAST/...UPDRAFT ORGANIZATION/ROTATION AIDED BY STEEP
   MID-LEVEL LAPSE RATES AND A VEERING 0-3-KM WIND PROFILE MAY MAINTAIN
   CONVECTIVE INTENSITY VIA DYNAMIC PRESSURE PERTURBATION PROCESSES.
   INDEED...SEVERAL REPORTS OF LARGE HAIL /INCLUDING A 3-INCH REPORT/
   IN SEWARD CO HAVE BEEN RECEIVED. AS SUCH...THE SEVERE THREAT
   CONTINUES ACROSS SRN PORTIONS OF WW 206. WHILE CELLS WILL LIKELY
   WEAKEN AS THEY PROGRESS EAST...A LOCAL AREAL EXTENSION BY A TIER OF
   COUNTIES EWD MAY BE NECESSARY IF CELLS MAINTAIN THEIR CURRENT
   INTENSITY.
