   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS OVER PARTS OF
   SOUTHERN GEORGIA AND NORTHERN FLORIDA...

   ...SUMMARY...
   Thunderstorms will pose a marginal severe-weather threat today
   across southern Georgia and northern Florida.

   ...FL/GA...
   Morning surface analysis shows a boundary extending from the FL
   panhandle east-northeastward to the GA coast.  Scattered showers and
   occasional thunderstorms have been occurring in vicinity of this
   boundary, including a few rotating/bowing structures.  Local VAD
   profiles suggest that low level winds are relatively veered,
   limiting the convergence along the boundary and the near-surface
   vertical shear profiles.  Abundant cloud cover will also likely
   persist through the day, limiting substantial destabilization.  CAM
   solutions suggest that deep convection will track across southern
   GA/northern FL through the afternoon. A severe storm or two is
   possible in this corridor, with locally damaging wind gusts the main
   threat.  An isolated tornado is also possible, but the overall
   severe threat appears to remain marginal.
