    Areas affected...portions of central into southern Alabama/Georgia

    Concerning...Severe potential...Watch possible=20

    Valid 252210Z - 252345Z

    Probability of Watch Issuance...60 percent

    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.
