   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 10 CONTINUES.
   
   SUMMARY...SCATTERED DAMAGING WIND/TORNADO THREATS WILL PERSIST
   WITHIN WW 10 FOR THE NEXT SEVERAL HOURS.
   
   DISCUSSION...THREE PRIMARY CORRIDORS OF SEVERE THREAT HAVE DEVELOPED

   EVENING. ONE...A QLCS ALONG A COMPOSITE COLD FRONT/OUTFLOW CURRENTLY
   EXTENDING FROM N-CNTRL AR TO ERN TX. TWO...A BAND OF SEMI-DISCRETE
   WARM SECTOR TSTMS FROM CNTRL AR TO NRN LA. PLEASE REFER TO MCD 0080

   00Z LZK/SHV/LCH RAOBS ALL SAMPLED SUFFICIENTLY BUOYANT PARCELS WITH
   PW VALUES JUST OVER 1.50 INCHES. THIS BUOYANCY IS FAVORABLE FOR
   PERSISTENT ROTATING UPDRAFTS GIVEN VERY LARGE LOW-LEVEL HODOGRAPHS
