   AREAS AFFECTED...ERN SC...SE GA AND NRN FL
   
   CONCERNING...TORNADO WATCH 7...
   
   VALID 052335Z - 060100Z
   
   A SEVERE THREAT WILL EXIST ACROSS NRN FL...SE GA AND ERN SC OVER THE
   NEXT FEW HOURS. A FEW TORNADOES AND ISOLATED WIND DAMAGE WILL BE
   POSSIBLE WITH THE STRONGER THUNDERSTORMS EMBEDDED IN THE LARGE AREA
   OF RAIN.
   
   LATEST SFC ANALYSIS SHOWS A COLD FRONT AND PRE-FRONTAL TROUGH
   EXTENDING SWD FROM THE SRN APPALACHIAN MTNS TO THE WRN FL PANHANDLE.
   THE LARGE AREA OF RAIN IS LOCATED WELL AHEAD OF THESE SFC FEATURES
   AND IS ASSOCIATED WITH A BAROCLINIC LEAF AHEAD OF A NEGATIVELY
   TILTED UPPER-LEVEL TROUGH. AHEAD OF THE RAIN...SFC DEWPOINTS ARE IN
   THE MID TO UPPER 60S F AND THE WARM SECTOR IS CHARACTERIZED MOSTLY
   BY WEAK INSTABILITY. A CENTER OF STRONG VERTICAL SHEAR EXISTS NEAR
   THE COAST OF GA WHERE OBJECTIVE ANALYSIS SHOWS 0-6 KM SHEAR VALUES
   OF 65 KT. THIS IS DUE TO STRONG ONSHORE SSELY FLOW AT THE SFC
   COUPLED WITH A SSWLY MID-LEVEL JET AROUND 60 KT LOCATED IN SE GA.
   THIS SHEAR ENVIRONMENT WILL CONTINUE TO BE FAVORABLE FOR LOW-TOPPED
   SUPERCELLS EMBEDDED IN THE LARGE AREA OF RAIN. ISOLATED WIND DAMAGE
   MAY ALSO OCCUR WITH THE BETTER ORGANIZED THUNDERSTORMS THROUGH EARLY
   EVENING.
