Areas affected...central and eastern FL Panhandle...far southwest GA
Concerning...Severe Thunderstorm Watch 174...
Valid 272034Z - 272200Z
The severe weather threat for Severe Thunderstorm Watch 174
continues.
SUMMARY...Scattered damaging gusts and perhaps a tornado will remain
possible through 5-6pm EDT.
DISCUSSION...Radar mosaic shows a north-northeast to south-southwest
oriented band of a thunderstorms move east across the northeast Gulf
of Mexico and central portions of the FL Panhandle late this
afternoon. Surface streamline analysis indicates weak easterly flow
across the central portion of the FL Panhandle during the past
couple of hours. Surface conditions ahead of the band of storms
have temperatures in the lower to mid 70s with dewpoints in the
lower 70s. A long-lived supercell has continued east-northeast
across the Panhandle with all hazards being exhibited via radar
during the past couple of hours. The band of storms and associated
convection on its leading edge is beginning to encroach on the
supercell with the potential for a tornado becoming more uncertain
with time. Nonetheless, a pronounced surge in the line supported by
strong deep-layer shear (effective shear 60 kt) will favor swaths of
damaging gusts as a weak mesolow begins to develop centered with
thunderstorms near Washington/Calhoun counties. Complex storm-scale interactions may continue to occur with both damaging gusts and
perhaps a brief mesovortex tornado possible as as the band moves
east during the next 1-2 hours.
