...THERE IS AN ENHANCED RISK OF SEVERE THUNDERSTORMS ACROSS PORTIONS
OF NORTHEAST LOUISIANA...CENTRAL AND SOUTHERN MISSISSIPPI...AND INTO
CENTRAL ALABAMA...

...SUMMARY...
Scattered severe thunderstorms are expected this afternoon and
evening from central Texas into the lower Mississippi and Tennessee
Valleys/southern Appalachians.  Supercells capable of all hazards
will be possible across portions of central Mississippi and Alabama
before a shift to a more of a damaging wind risk into the late
evening/overnight.

...TX/Lower MS Valley into the Southeast...
A corridor of strong mid to high-level west-southwesterly flow
extends from TX into the central and southern Appalachians to the
southeast of a larger-scale positively tilted trough with embedded
shortwaves.  Morning surface mesoanalysis depicted a cold front
slowly moving southward across south-central TX through northern MS
and into the southern Appalachians.  South of the boundary, a
quasi-zonal flow regime with little mid-level height change is
expected through tonight.  A moist airmass maintained by southerly
flow will yield surface dewpoints ranging from the mid-upper 60s to
lower to mid 70s deg F south of the front.  Despite extensive cloud
cover owing to the moist boundary layer (reference the 16 g/kg
lowest 100-mb mean mixing ratios from the 12 UTC Lake Charles and
Slidell, LA raobs), heating and persistent weak low-level warm
advection will combine to erode convective inhibition and yield
scattered storms developing later this afternoon.  Moderately steep
mid-level lapse rates and seasonably rich moisture/PW will support
strong buoyancy ahead of the front (i.e. 2500 J/kg of MLCAPE) over
LA/MS.  Gradual intensification of storms in the moist environment
will likely result in several strong supercells eventually
developing late this afternoon through the evening.  Large to very
large hail, damaging gusts, and tornadoes will be possible with the
stronger storms.  The tornado risk is forecast to peak late this
afternoon through the evening as southwesterly 850-mb flow
strengthens from 25 kt to 35-40 kt. Environmental conditions support
the potential for a strong tornado during this timeframe.  Whether
or not storms can realize this increasing low-level shear will
largely be a function of storm mode.  Storms should eventually begin
to cluster and to grow upscale, with an increasing damaging wind
threat continuing downstream into Alabama and Georgia.

The front will continue slowly southward, and the very moist 
environment could support additional warm sector storms throughout
much of the evening and overnight, supporting a continued risk for
all severe hazards, perhaps extending into northern GA and Upstate
SC late tonight.
