Areas affected...portions of central and southern

Concerning...Tornado Watch 17...18...
Valid 220549Z - 220745Z
The severe weather threat for Tornado Watch 17, 18 continues.
SUMMARY...Severe weather risk -- including some tornado potential --
DISCUSSION...Latest radar loop shows widespread convection -- with
local/embedded severe storms -- ongoing across parts of central and
southern Alabama and into portions of Georgia and the Florida
Panhandle (in and near Tornado Watch 18). Overall convective trends
have been downward, with the stronger convection now almost entirely
north of the warm front (which currently extends from central MS
southeast to the FL/AL border and east across southern GA).
With that said, an increase in northeast-moving cellular convection
is noted south of the warm front over the northern Gulf/east of the
LA coast, with some lightning now observed over the FL Panhandle
area as cells near the frontal zone. While low-level flow south of
the warm front has veered, some tornado risk may exist as these
storms cross the warm front. Elsewhere/farther north, risk for a
tornado or two, along with potential for local wind damage and
marginal hail, will continue over the next 1-2 hours.
