    Areas affected...Extreme northern MS into western/middle TN

    Concerning...Tornado Watch 107...

    Valid 031923Z - 032100Z

    The severe weather threat for Tornado Watch 107 continues.

    SUMMARY...An increasing severe threat is expected this afternoon,
    including potential for tornadoes, damaging wind, and isolated hail.

    DISCUSSION...A small storm cluster has recently intensified across
    western TN, with other showers and small cells developing south and
    east of this cluster, in the vicinity of an outflow-reinforced
    front. The front earlier moved northward across middle TN, but has
    shown signs of stalling or beginning to sag southward over the last
    hour.=20

    The storm cluster moving out of western TN appears likely to
    traverse the area along and just south of the front, within an
    environment characterized by moderate MLCAPE (1000-1500 J/kg),
    strong (60+ kt) deep-layer shear, and generally favorable low-level
    shear/SRH. One or more embedded supercells within this cluster may
    become capable of producing tornadoes, especially near the surface
    boundary, along with a threat of large to locally very large hail
    and damaging winds. A strong tornado is possible, especially if any semi-discrete supercells can be sustained.=20

    Additional cells developing across far northeast MS into southwest
    TN may also mature into supercells, posing a threat of hail,
    damaging winds, and possibly a strong tornado if the cells can
    persist along/south of the boundary within the warm sector.=20

    Aside from the potential for surface-based supercells, a few
    stronger elevated cells/clusters also remain possible north of the
    front, with a threat for hail and damaging wind.
