   CONCERNING...TORNADO WATCH 5...6...
   
   VALID 172023Z - 172200Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 5...6...CONTINUES.
   
   NRN ZONE OF STORMS FROM TPA TO MLB HAS WEAKENED AS THE INFLUENCE OF
   THE UPPER SHORTWAVE TO THE N HAS WANED AND STORM ARE NO LONGER BEING
   GENERATED UPSTREAM ALONG THE BOUNDARY. WITH CLOUDS AND RAIN
   OVERSPREADING MUCH OF THE AREA...FURTHER DESTABILIZATION IS UNLIKELY
   
   
   FARTHER S...WIDESPREAD RAIN AND EMBEDDED STORMS HAVE ALSO OVERSPREAD
   FAR SRN FL...WITH A FEW CELLS SHOWING ROTATION OFF THE SERN COAST.
   SURFACE ANALYSIS...AS WELL AS AN 18Z KEY SOUNDING...SHOWS A
   MODERATELY UNSTABLE AIR MASS WITH DEWPOINTS RISING TO AROUND 70 F.
   ALTHOUGH WIND ALOFT ARE VEERING...ADDITIONAL ACTIVITY IS INCREASING
   IN INTENSITY W OF THE KEYS. THESE STORMS WILL LIKELY CONTAIN STRONG
   AND POSSIBLY DAMAGING WIND GUSTS AS THEY AFFECT THE FL KEYS AND
   EVENTUALLY THE SRN PENINSULA. THE TORNADO THREAT APPEARS TO BE
   LESSENING WITH TIME AS HODOGRAPHS BECOME STRAIGHT...BUT INCREASING
   WIND FIELDS ALOFT COULD COMBINE WITH ORGANIZED LINES/BOWS TO PRODUCE
   WIND DAMAGE.
