Areas affected...Portions of southern GA and northern FL

Concerning...Tornado Watch 21...

Valid 222119Z - 222245Z

The severe weather threat for Tornado Watch 21 continues.

SUMMARY...A line of potentially tornadic supercells will continue
tracking eastward around 40-50 kt into the late afternoon hours.
Long-track, fast-moving, strong tornadoes will be possible.

DISCUSSION...A line of discrete/semi-discrete supercells and
supercell clusters extending from southern GA to eastern portions of
the FL Panhandle will continue spreading eastward around 40-50 kt.
Approximate times of arrival of this line are depicted in the
accompanying graphical product. Very strong wind fields accompanying
a rapidly deepening cyclone over east-central AL will continue to
support long, curved hodographs. As southerly mass fluxes east of
the cyclone continue to support the northward advance of a
precipitation-enhanced boundary across southern GA -- with moderate
instability south of this boundary -- the supercell-tornado risk
should continue to develop northward across parts of southern GA.
The potential for strong, long-track, fast-moving tornadoes will
continue.
