   MESOSCALE DISCUSSION 1222
   NWS STORM PREDICTION CENTER NORMAN OK
   0335 PM CDT SUN JUN 28 2015

   AREAS AFFECTED...NERN/ERN MO

   CONCERNING...TORNADO WATCH 367...

   VALID 282035Z - 282230Z

   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 367 CONTINUES.

   SUMMARY...SUPERCELLS APPEAR IMMINENT WITH TORNADOES POSSIBLY
   DEVELOPING BY 21-22Z.

   DISCUSSION...LATEST RADAR TRENDS SHOW CELLS RAPIDLY DEVELOPING ON
   THE OUTFLOW BOUNDARY OVER NERN MO...FROM KNOX COUNTY SEWD. THIS AREA
   IS AN ENVIRONMENT CONSISTING OF AROUND 300 M2/S2 EFFECTIVE SRH ALONG
   WITH A SLIGHTLY SHELTERED/MOIST BOUNDARY LAYER AND PLUME OF
   LOW-LEVEL LAPSE RATES FEEDING INTO THE AREA. 

   AIR TO THE E OF THE KNOX COUNTY CELL IS A BIT COOL...BUT THE
   BOUNDARY COULD MOVE EWD. STILL...THE MOST LIKELY SCENARIO IS FOR
   THESE CELLS TO SLOW DOWN AS THEY TAKE ROOT INTO THE BOUNDARY
   LAYER...THEN TURN/PROPAGATE SEWD ALONG THE BOUNDARY WITH A TORNADO
   THREAT. OTHER CELLS THAT CONTINUE MOVING IN A RELATIVELY LEFTWARD
   DIRECTION MAY STILL YIELD A HAIL THREAT FARTHER E.
