    Concerning...Tornado Watch 78...

    Valid 022134Z - 022300Z

    The severe weather threat for Tornado Watch 78 continues.

    SUMMARY...The potential for multiple discrete supercells and
    attendant tornadoes is increasing along an axis from southwest Ohio
    into central Kentucky and northern Middle Tennessee.

    DISCUSSION...Regional radars show a line of thunderstorms
    intensifying from southeast IN into west-central KY and northwest
    TN. Multiple cells in this line have developed mid-level rotation
    in the past 45 min, with reported tornadoes in the storm west of
    Cincinnati. Clouds have thinned ahead of this activity, where
    temperatures have locally warmed into the mid 70s along with
    dewpoints in the mid 60s. A 50+ knot southerly low-level jet is
    aiding in impressive shear parameters, with VAD profiles showing
    0-3km SRH values of 300-500 m2/s2. Discrete supercells in this line
    appear to be the primary concern for tornadoes (potentially strong)
    during the next 1-2 hours. Steep mid-level lapse rates will also
    promote large hail in the stronger cells.
