    Areas affected...Central/East-Central MS...West-Central AL

    Concerning...Tornado Watch 13...15...16...

    Valid 092250Z - 100015Z

    The severe weather threat for Tornado Watch 13, 15, 16 continues.

    SUMMARY...Threat for damaging wind gusts and perhaps a brief tornado
    will continue across central/east-central MS and west-central AL for
    the next few hours.

    DISCUSSION...Regional radar imagery reveals two somewhat more
    organized storm clusters, one moving through Calhoun county MS and
    the other in Holmes and Carroll counties in central MS. Downstream
    air mass, particularly immediately downstream of the Holmes/Carroll
    cluster, appears favorable for storm persistence and perhaps
    strengthening. In this area, a corridor of slightly higher dewpoints
    (i.e. around 64 deg F) exists amidst moderate southerly surface
    winds and strong vertical shear. Storm motion of both of these
    storms is northeasterly at 45 kt, taking them to the MS/AL border
    around 00Z. A extension in time will be needed for a few southern
    counties Tornado Watch 13 given its current expiration time of 23Z.
