Interesting situation in regards to severe weather tomorrow. Threat is conditional. Depending on how atmosphere recovers. SPC mentioning the possibility of some low topped super cells. If instability can be realized. I love a good low topper!
Extensive convection will likely be ongoing Saturday morning from
near the LA Gulf Coast into parts of MS/AL, within the warm conveyor
region of the developing cyclone. Rich low-level moisture and
favorable low-level and deep-layer shear will support organized
convection, with some morning threat for locally damaging wind and
possibly a tornado or two from southeast LA into southern MS/AL and
eventually the FL Panhandle. This initial band of convection may
reach southwest GA by early afternoon with an isolated severe
threat, before weakening as large-scale ascent becomes displaced to
the north.
In the wake of morning convection, some low-level moistening is
expected across much of AL into far southern TN, in advance of a
cold front that will be moving eastward in conjunction with the
surface low. Relatively steep midlevel lapse rates will also
overspread the region, resulting in the potential for MLCAPE to
increase to at least 500 J/kg range, though the magnitude of
destabilization will depend on the extent of heating/moistening in
the wake of morning convection, which remains uncertain at this
time. If robust convection can evolve and be sustained, a few
relatively low-topped supercells may evolve with time along/ahead of
the cold front and spread eastward with a threat of a couple
tornadoes, isolated damaging wind, and small to perhaps marginally
severe hail.
