New Severe Thunderstorm Watch Coming for Counties to South of Current One

Jason Davis at the NWS Birmingham asks a new severe thunderstorm watch is being coordinated for counties to the south of the current one.

Here is the MCD from the SPC;

SUMMARY…Ongoing cluster of strong to severe storms may continue
southeastward with a risk primarily for damaging gusts and some
hail. Conditions are being monitored for a possible downstream
Watch.

DISCUSSION…As of 22 UTC, regional radar analysis showed a cluster
of ongoing strong to severe storms across portions of AL and GA
within WW377. Over the last couple of hours, this cluster has
gradually become loosely organized into an MCS, as surface cold
pools have consolidated. Intensity has fluctuated somewhat, but
moderate buoyancy should continue to be sufficient for strong
updraft maintenance. Vertical shear decreases with southward extent,
but 20-25 kt of effective shear from area VADs may remain supportive
of organized multicells. The presence of a strong cold pool also
suggests storms may remain organized despite limited vertical shear.
Damaging wind gusts and some hail are possible as storms track south
and east with time. Greater buoyancy across portions of southeastern
AL may favor preferential propagation along the southwestern most
portions of the line tonight. Recent HRRR runs are also supportive
of this scenario with the main MCS shifting toward the AL/GA border
later this evening. Given the potential for damaging wind gusts and
hail this evening, a Watch is being considered.
