   AREAS AFFECTED...ERN KY THROUGH WRN HALF OF WV AND EXTREME SWRN VA
   
   CONCERNING...TORNADO WATCH 58...62...
   
   VALID 030037Z - 030200Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 58...62...CONTINUES.
   
   THREAT FOR STRONG TORNADOES...DAMAGING WIND AND VERY LARGE HAIL WILL
   CONTINUE THROUGH MID EVENING THROUGH THE REMAINDER OF ERN KY...THE
   WRN HALF OF WV INTO SWRN VA.
   
   SEVERAL TORNADIC SUPERCELLS CONTINUE THROUGH ERN KY...WRN WV AND
   SWRN VA WITHIN AN ENVIRONMENT CHARACTERIZED BY VERY LARGE 0-1 KM
   HODOGRAPHS...60-70 KT EFFECTIVE BULK SHEAR AND 500 J/KG MLCAPE.
   TENDENCY HAS BEEN FOR SOME STORMS TO EVOLVE INTO LINES...BUT A FEW
   DISCRETE SUPERCELLS REMAIN AHEAD OF THE LINE. THE UPSCALE GROWTH
   WILL INCREASE THE POTENTIAL FOR DAMAGING WIND...BUT THREAT FOR
   TORNADOES WILL PERSIST WITH ANY SUPERCELLS EMBEDDED WITHIN OR AHEAD
   OF THE LINE.
   
   LATEST SURFACE ANALYSIS INDICATES A WEDGE FRONT PERSISTING FROM WRN
   NC INTO ERN WV. THE SURFACE LAYER EAST OF THIS BOUNDARY IS STABLE
   WITH TEMPERATURES IN THE 40S TO AROUND 50F...SUGGESTING THE STORMS
   SHOULD BEGIN TO WEAKEN LATER THIS EVENING AS THEY CROSS INTO THE
   COOLER AIR OVER ERN WV AND FARTHER EAST INTO VA.
