   SUMMARY...THE SVR RISK CONTINUES ACROSS REMAINING VALID PORTIONS OF
   TORNADO WATCHES 58 AND 59.

   DISCUSSION...A LARGE LEADING-LINE/TRAILING-STRATIFORM MCS CONTINUES
   SPREADING ACROSS PARTS OF THE LOWER MS AND THE TN VALLEY.
   STRENGTHENING MID-LEVEL SWLYS ARE FOCUSING THE STRONGEST FORWARD
   PROPAGATIONAL COMPONENT OF THIS SYSTEM AND DMGG WIND/TORNADO
   POTENTIAL INTO PARTS OF MIDDLE TN...WHERE WW 59 HAS BEEN EXPANDED
   NWD. FARTHER S ACROSS AL INTO CNTRL MS AND NERN LA...INSTANCES OF
   DMGG WIND GUSTS MAY BE MORE SPORADIC AS THE CONVECTIVE LINE IS
   ASSUMING A MORE PARALLEL ORIENTATION TO THE FLOW ALOFT.

   SUPPORT SOME POTENTIAL FOR DMGG WIND GUSTS WITH EMBEDDED BOWING
   SEGMENTS. THIS POTENTIAL MAY SPREAD E OF WW 59 IN AL...PERHAPS
   WARRANTING AN EWD EXTENSION OF THE TORNADO WATCH. THE SVR RISK WILL
   BE NIL BEHIND THE CONVECTIVE LINE.
