   ...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS FROM SOUTHEAST
   GEORGIA THROUGH EASTERN SOUTH CAROLINA...

   ...SUMMARY...
   A strong wind gust or two and a brief tornado remain possible this
   evening from southeast Georgia into eastern South Carolina.

   ...Southeast Georgia through eastern South Carolina...

   Band of relatively shallow convection with only a few embedded
   lightning flashes persists along the warm conveyor belt from the
   central FL Panhandle northeastward through the Middle Atlantic
   region. The best chance for any additional severe weather this
   evening exists from southeast GA, northeastward along and south of a
   warm front situated across central SC. Surface based-convection in
   this region will remain within vertical wind profiles sufficient for
   a couple of rotating updrafts or bowing segments. The thermodynamic
   environment in this region is very marginal, and a cooling surface
   layer suggests most updrafts will probably remain slightly elevated.
   Nevertheless, a strong wind gust and a brief tornado cannot be ruled
   out primarily through about 03Z.
