   MESOSCALE DISCUSSION 0766
   NWS STORM PREDICTION CENTER NORMAN OK
   0500 PM CDT FRI MAY 27 2016

   AREAS AFFECTED...WESTERN KS

   CONCERNING...SEVERE THUNDERSTORM WATCH 224...

   VALID 272200Z - 272330Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 224
   CONTINUES.

   SUMMARY...ISOLATED SEVERE STORMS CAPABLE OF BRIEF TORNADOES AND HAIL
   WILL CONTINUE OVER PARTS OF WESTERN KS FOR ANOTHER 1-2 HOURS.

   DISCUSSION...RADAR LOOP SHOWS SEVERAL SEMI-DISCRETE STORMS THAT ARE
   FORMING EAST OF A SURFACE LOW NEAR GREELEY COUNTY KS...AND ALONG
   ALONG THE PACIFIC COLD FRONT EXTENDING EASTWARD INTO CENTRAL KS. 
   SOUTHERLY-ORIENTED DEEP LAYER SHEAR VECTORS ARE NORMAL TO THE E-W
   BOUNDARY...ALLOWING CELLS TO REMAIN MOSTLY DISCRETE. 
   MEANWHILE...STORMS ARE TRACKING WESTWARD AND REMAINING IN THE
   VICINITY OF THE BOUNDARY.  THIS ALLOWS THE UPDRAFTS TO INTERACT WITH
   ENHANCED LOW-LEVEL VORTICITY AND SHEAR AND IS LEADING TO SEVERAL
   BRIEF TORNADO REPORTS.  THIS PROCESS MAY CONTINUE FOR ANOTHER HOUR
   OR TWO UNTIL STORMS EXHAUST THE INSTABILITY ALONG THE BOUNDARY AND
   DAYTIME HEATING ENDS.  STRONGER UPDRAFTS ALONG THIS CORRIDOR WILL
   ALSO POSE A THREAT OF LARGE HAIL.
