   VALID 250438Z - 250615Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 16 CONTINUES.
   
   THE SEVERE THREAT ASSOCIATED WITH A SQUALL-LINE FROM SRN KY SSWWD TO
   CNTRL MS WILL CONTINUE EWD TONIGHT ACROSS THE REMAINDER OF THE TN
   VALLEY INTO THE SRN APPALACHIAN MTNS. A WW LIKELY BE NEEDED TO THE
   EAST OF WW 16 AND 17.
   
   A SQUALL-LINE WITH SEVERAL LEWP SEGMENTS IS ONGOING JUST TO THE EAST
   OF A POWERFUL 60 TO 75 KT LOW-LEVEL JET. THIS FEATURE IS CREATING
   VERY STRONG SPEED SHEAR JUST ABOVE THE SFC WHICH ALONG WITH A
   FORWARD SPEED OF THE LINE AT 40-45 KT WILL CREATE A FAVORABLE
   ENVIRONMENT FOR WIND DAMAGE. STRONG LARGE-SCALE ASCENT AHEAD OF AN
   OZARKS UPPER-LEVEL TROUGH WILL PROVIDE SUPPORT FOR THE SQUALL-LINE
   FOR A FEW MORE HOURS AS THE LINE MOVES INTO SE KY...ERN TN...NE AL
   AND FAR NW GA. HOWEVER...INSTABILITY IS VERY WEAK AHEAD OF THE LINE
   AND THE LINE SHOULD BECOME LESS INTENSE WITH TIME. THIS SHOULD
   RESULT IN THE WIND DAMAGE THREAT BECOMING INCREASINGLY ISOLATED
   AFTER 06Z.
