...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS ACROSS SOUTHERN
AL...SOUTHWEST GA...AND THE FL PANHANDLE...

...SUMMARY...
Severe thunderstorms are possible across portions of the Southeast
states this morning and afternoon. Damaging gusts and a few
tornadoes are the main concerns.

...Portions of the Southeast States...
Early-morning satellite imagery shows a southern-stream shortwave
trough moving across the southern Plains and into the more
single-stream confluent flow across the eastern CONUS. Surface
analysis places the low associated with this shortwave over the
central MS/AL border vicinity. A cold front extends from this low
southwestward through southeast LA and into the western Gulf.
Combination of these features compose the large winter storm system
that is impacting much of the central and eastern CONUS.

Recent regional radar imagery and surface observations reveal an
extensive area of anafrontal showers and thunderstorms from east TX
into MS and TN Valley. Much of this precipitation is falling as
either freezing rain or sleet, with sporadic lightning accompanying
this winter precipitation across east TX, northern/central LA, and
western/northwestern MS. Currently, the warm sector, which extends
from southeast LA across southern AL and southern MS into the FL
Panhandle, is free of any thunderstorms. This is expected to change
throughout the morning as continued moisture advection further
modifies the airmass and modest buoyancy develops ahead of the
advancing cold front. Despite the fast progression of the cold
front, strong deep-layer vertical shear should allow for the
maintenance of deep convection along the frontal zone once it begins
to encounter the modest buoyancy. Additionally, the strong vertical
shear should also allow for some organization/rotation within any
deeper, more persistent updrafts.

Damaging gusts appear to be the primary severe risk, with the risk
concentrated from southern AL and the western FL Panhandle into
southwest GA and the central FL Panhandle where the best
thermodynamics (i.e. 500-1000 J/kg of MLCAPE) are forecast.
Low-level shear is strong enough to support a tornado risk in this
area as well, with the linear nature of the convection favoring
brief cell-in-line/QLCS circulations (in contrast to a more
discrete, supercellular mode). A few discrete cells ahead of the
line cannot be entirely ruled out. However, limited residence time
due to the fast-moving front and likely shallow character due to
limited buoyancy should prevent these updrafts from maturing.
