    Areas affected...Portions of western/southern Indiana

    Concerning...Tornado Watch 10...

    Valid 192326Z - 200100Z

    The severe weather threat for Tornado Watch 10 continues.

    SUMMARY...Tornado Watch #10 continues until 0200 UTC. A supercell
    thunderstorm currently tracking across northern portions of the
    watch in far western/southern Indiana is the primary focus for
    severe activity in the short term, and has a history of rotation and
    brief tornadoes.

    DISCUSSION...The supercell thunderstorm tracking across the northern
    portions of Tornado Watch #10 is the primary concern for severe
    weather in the next 1-2 hours, with a history of rotation and
    tornado production. While further north in the cooler air, VWP
    profiles from KIND show strong curvature of the hodograph in the
    lowest levels which will help support continued mesocyclone and
    tornado development, with values in the 0-500m layer 120 m2/s2. Even
    further south away from the frontal boundary, profiles from KLVX
    still show strong support for low-topped supercell longevity.
    However, some uncertainty exists in how far eastward current
    convection will be maintained given only modest dewpoints in the
    low-to-mid 50s F. In spite of this, the cooler temperatures aloft
    and buoyancy evident in proximity sounding profiles, combined with=20
    the strong kinematics discussed and history of tornado production,
    the expectation is that severe convection should continue eastward
    into central Indiana for at least the next two hours. This supercell
    will continue to be capable of all hazards, including a strong
    tornado.
