MESOSCALE DISCUSSION 0508
  NWS STORM PREDICTION CENTER NORMAN OK
  0253 PM CDT MON MAY 10 2010
 
  AREAS AFFECTED...PARTS OF S CNTRL/SERN KS...N CNTRL AND NE OK
 
  CONCERNING...TORNADO WATCH 147...
 
  VALID 101953Z - 102130Z
 
  THE SEVERE WEATHER THREAT FOR TORNADO WATCH 147 CONTINUES.
 
  THE RISK FOR STRONG TORNADOES APPEARS LIKELY TO INCREASE DURING THE
  NEXT FEW HOURS.
 
  THE SURFACE WARM FRONT APPEARS TO BE STRENGTHENING NEAR THE
  KANSAS/OKLAHOMA BORDER AREA...AND THE DRY LINE/WARM FRONT
  INTERSECTION NOW APPROACHING MEDICINE LODGE IS BECOMING THE FOCUS
  FOR STRONGEST FORCING FOR UPWARD VERTICAL MOTION AND
  DESTABILIZATION...AS THE EXIT REGION OF THE STRONG 500 MB JET STREAK
  OVERSPREADS IT.  MODELS ARE SUGGESTIVE THAT THIS BOUNDARY
  INTERSECTION WILL DEVELOP EASTWARD NEAR THE STATE BORDER AREA
  ...SOUTH OF WICHITA/NORTH OF STILLWATER...BETWEEN NOW AND 23-00Z.
  AS SURFACE DEW POINTS INCREASE THROUGH THE MID/UPPER 60S AND
  LOW-LEVEL LAPSE RATES CONTINUE TO STEEPENING...IN THE PRESENCE OF
  LARGE CLOCKWISE CURVED LOW-LEVEL HODOGRAPHS ACROSS THIS
  REGION...POTENTIAL FOR SUPERCELLS TO PRODUCE STRONG TORNADOES
  APPEARS LIKELY TO INCREASE LATE THIS AFTERNOON.
