   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 666
   CONTINUES.
   
   THE SEVERE THREAT IS DIMINISHING ACROSS SERN TX AND SRN/WRN LA WITH
   THE LOSS OF HEATING AND SIGNIFICANT OUTFLOW PRODUCTION. SEVERE
   STORMS THAT TRAVELED FROM NRN LA INTO NERN TX DISSIPATED
   QUICKLY...AND ALTHOUGH AN UNSTABLE AIR MASS REMAINS OVER MUCH OF THE
   AREA APART FROM OUTFLOW...LITTLE IMPETUS EXISTS FOR FURTHER
   DEVELOPMENT. AN ISOLATED STRONG STORM CANNOT BE RULED OUT THROUGH
   EARLY EVENING...WITH MAINLY WIND GUST POTENTIAL. OTHERWISE...THE
   REMAINDER OF WW 666 MAY BE CANCELED EARLY.
