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.
