   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.
