TORNADO WATCHES 58 AND 59.

SPREADING ACROSS PARTS OF THE LOWER MS AND THE TN VALLEY.
STRENGTHENING MID-LEVEL SWLYS ARE FOCUSING THE STRONGEST FORWARD

SUPPORT SOME POTENTIAL FOR DMGG WIND GUSTS WITH EMBEDDED BOWING

WARRANTING AN EWD EXTENSION OF THE TORNADO WATCH. THE SVR RISK WILL
BE NIL BEHIND THE CONVECTIVE LINE.
