    Areas affected...lparts of sern MS into cntrl AL

    Concerning...Tornado Watch 130...131...

    Valid 061037Z - 061230Z

    The severe weather threat for Tornado Watch 130, 131 continues.

    SUMMARY...Storms overspreading areas near/northeast of Pine Belt MS
    into areas near/south of Tuscaloosa AL will pose a risk for
    producing additional tornadoes through 7-8 AM CDT.

    DISCUSSION...Several meso-beta to meso-gamma scale circulations have
    evolved along the gust front slowly advancing eastward through
    southeastern Mississippi, with 2-hourly surface pressure falls in
    excess of 2 mb noted on the Pine Belt MS surface observations the
    past couple of hours. A couple of these circulations appear to have
    briefly intensified to tornadic strength, based on storm-relative
    velocity data and debris signatures. Supported by southeasterly
    updraft inflow emanating from a narrow corridor of moderately large
    CAPE across southeastern Mississippi into portions of west central
    Alabama (where surface dew points remain near 70f), it appears that
    this activity may maintain strength while gradually spreading
    eastward through 11-13Z.

    Intensification of one or two additional discrete cells just ahead
    of the line also appears possible near/east to northeast of Pine
    Belt during the next couple of hours, accompanied by potential to
    produce a tornado in the presence of sizable clockwise-curved
    low-level hodographs.
