    Areas affected...Northern MS...northwest AL...southwest TN

    Concerning...Tornado Watch 124...125...

    Valid 052318Z - 060045Z

    The severe weather threat for Tornado Watch 124, 125 continues.

    SUMMARY...The threat for tornadoes, damaging wind, and isolated hail
    will spread eastward through the evening.

    DISCUSSION...A small storm cluster with embedded supercells has
    evolved across north-central MS this evening, with another cluster
    noted into southwest TN. The environment downstream of the southern
    cluster remains favorable for tornadic supercells, with strong
    buoyancy (with MLCAPE of 2000-3000+ J/kg), favorable boundary-layer
    moisture and deep-layer shear, and locally backed surface winds
    supporting 0-1 km SRH above 200 m2/s2. Despite the complex storm
    mode, the presence of embedded supercells within this environment
    will continue to support a tornado threat, including strong-tornado
    potential. One or more swaths of severe/damaging wind will also be
    possible with these clusters, along with isolated hail.=20

    Buoyancy is somewhat weaker into southern TN, but some threat for
    all severe hazards may accompany the northernmost cluster as it
    encounters a downstream outflow boundary.
