   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 147...148...CONTINUES.
   
   ...NEW TORNADO WATCH WILL BE ISSUED SOON FOR PORTIONS OF SERN
   KS...SWRN MO...NERN OK...NWRN AR...
   
   RAPID BOUNDARY LAYER RECOVERY IS UNDERWAY ACROSS SCNTRL KS INTO NERN
   OK AHEAD OF SFC LOW ALONG THE KS/OK BORDER WEST OF PNC.  FOCUSED
   PRESSURE FALLS ARE NOTED JUST AHEAD OF THIS FEATURE WITH 2 HOUR
   FALLS ON THE ORDER OF 4-7MB.  NEEDLESS TO SAY SHEAR AND
   THERMODYNAMIC PARAMETERS ARE UNUSUALLY STRONG AND VERY SUPPORTIVE OF
   VIOLENT TORNADIC SUPERCELLS.  LATEST RADAR TRENDS SUGGEST EARLIER
   ISOLATED ACTIVITY IS NOW MORE CONCENTRATED AND FOCUSED ALONG SURGING
   DRYLINE WITH AT LEAST HALF A DOZEN STRONG TO RAPIDLY INTENSIFYING
   SUPERCELLS...A FEW WITH POTENTIALLY SIGNIFICANT TORNADOES...FROM
   KINGMAN COUNTY KS...ARCING TO THE WEST AND SOUTHWEST OF OKC IN SWRN
   OKLAHOMA.
   
   LATEST THINKING IS SPEED/MOVEMENT OF CURRENT ACTIVITY WILL REQUIRE
   AN ADDITIONAL TORNADO WATCH TO BE ISSUED OVER SERN KS/SWRN MO/NERN
   OK/NWRN AR SHORTLY.
