    Areas affected...portions of northern MS into Middle TN

    Concerning...Tornado Watch 104...

    Valid 030955Z - 031130Z

    The severe weather threat for Tornado Watch 104 continues.

    SUMMARY...The tornado risk may persist across portions of northern
    Mississippi into Middle Tennessee another few hours. A local watch
    extension may be needed.

    DISCUSSION...Occasionally intense cells exhibiting moderate rotation
    continue along the stalled surface boundary from northern MS into
    Middle TN early this morning. A supercell southwest of the Nashville
    area has recently shown increasing rotation over the past 20
    minutes. Wind profile data from GWX and HUN continue to show
    supercell wind profiles across the warm sector, while a narrow
    corridor of modest MLCAPE extends northeast across the MCD area.
    Convection may continue to be sustained in the warm advection regime
    along the surface boundary and within a favorably sheared
    environment such that tornado/severe potential could persist a few
    more hours. With Tornado Watch 104 set to expire at 11z, a local
    watch extension may be needed.
