   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 246 CONTINUES.
   
   ALTHOUGH AN ISOLD TORNADO REMAINS POSSIBLE OVER THE NEXT HOUR OR
   TWO...A GENERAL WEAKENING TREND HAS BEEN OBSERVED OVER THE WATCH
   AREA.
   
   ALTHOUGH CONVECTION CONTINUES TO DEVELOP NEAR THE STATIONARY
   FRONT...LITTLE ROTATION/SUPERCELLULAR STRUCTURE HAS BEEN OBSERVED
   RECENTLY. WEAKENING TREND IS LIKELY PRIMARILY TIED TO DIURNAL
   COOLING AND HEIGHT RISES AS THE SHORT WAVE RESPONSIBLE FOR STRONGER
   CONVECTION MOVES OFFSHORE...AND THE LARGER SCALE TROUGH BEGINS TO
   LIFT NEWD. AS THIS OCCURS...RECENT VAD WIND PROFILE DATA INDICATES
   SUBTLY DECREASING WINDS...WHILE AT THE SURFACE WINDS ARE GENERALLY
   VEERING. AS COOLING/INCREASING CINH CONTINUES...CONVECTION WILL
   PRIMARILY BECOME ELEVATED...WITH A THREAT OF MARGINALLY SEVERE HAIL.
   AS STORMS CONTINUE TO WEAKEN...THE WW MAY BE CANCELLED EARLY.
