   Areas affected...Southern GA...extreme southeast AL...and part of
   the FL Panhandle

   Concerning...Tornado Watch 19...

   Valid 221211Z - 221415Z

   The severe weather threat for Tornado Watch 19 continues.

   SUMMARY...Severe weather -- including a continued tornado potential
   -- continues across WW 19.

   The northwest quadrant of WW 19 is expected to have a continued lull
   in thunderstorm development until about 15Z, at which time newly
   developing strong to severe storms should be moving into this region
   from the west/southwest.

   DISCUSSION...At 1140Z, mosaic radar imagery showed a corridor of
   strong to severe storms extending from the northeast corner of WW 19
   in southeast GA to central and eastern parts of the FL Panhandle,
   with additional storms developing between this axis of storms and
   the warm front. Early morning surface analysis showed an area of low
   pressure near EUF (Eufaula, AL), with a warm front extending east
   through the northern part of WW 19 in southern GA.  An influx of
   moisture-rich air has spread north overnight into southern GA, with
   surface dew points in the upper 60s to 70 F located along and south
   of the aforementioned axis of strong to severe storms.  The
   combination of effective bulk shear at or above 50 kt and mucape of
   750-1500 J/kg will continue to support organized storms, while
   effective SRH of 300-600 m2/s2 favors a continued tornado threat.
