   VALID 262145Z - 262315Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 726 CONTINUES.
   
   THE DAMAGING WIND THREAT WILL CONTINUE THE NEXT FEW
   HOURS...ESPECIALLY OVER NORTHERN PORTIONS OF THE WATCH.
   HOWEVER...TORNADO THREAT IS DIMINISHING.
   
   21Z MESOANALYSIS INDICATED VERY LITTLE INSTABILITY WITH MLCAPE
   VALUES AROUND A COUPLE HUNDRED AT BEST OVER SOUTHERN PORTIONS OF WW
   726. GIVEN THE LOW CAPE ENVIRONMENT AND POOR LAPSE RATES /5.5-6.5
   C/KM IN LOW AND MID LEVELS/ THE TORNADO THREAT WILL QUICKLY DIMINISH
   WITH THE EWD PROGRESSION OF THE SYSTEM. HOWEVER...GIVEN INTENSE LOW
   LEVEL SHEAR AS NOTED ON SEVERAL REGIONAL VWPS...DAMAGING WIND GUSTS
   WILL STILL BE POSSIBLE THE NEXT FEW HOURS.
