Areas affected...parts of GA to the FL Panhandle
Concerning...Tornado Watch 723...
Valid 290906Z - 291030Z
The severe weather threat for Tornado Watch 723 continues.
SUMMARY...Potential for brief tornadoes and sporadic damaging winds
from strong gusts should persist through sunrise as a QLCS
progresses across Georgia and the Florida Panhandle.
DISCUSSION...Overall severe potential has subdued slightly in the
early morning hours as the faster-moving/north-south oriented
portion of the QLCS spread into GA from AL. Despite the presence of
a 60-kt rear inflow jet per the MXX and EOX VWP data, measured
surface gusts have largely ranged from 40-55 mph. The forward motion
of this line at around 45 kts appears to be outpacing MLCAPE in
excess of 500 J/kg. Still, low to mid 60s surface dew points have
become common across central GA and will support scant to meager
buoyancy downstream. This should be sufficient for a sporadic wind
damage and brief tornado threat given the strong low-level
winds/SRH.
The trailing portion of the QLCS in the western FL Panhandle has
been steadily moving east at around 25 kts, lagging well behind the
west-central GA portion. Rich low-level moisture combined with
sufficient shear will support potential for tornadogenesis and
occasional strong gusts. These threats may tend to be focused near
the coast where inflection in the large-scale convective outflow is
maintained.
