    Areas affected...Parts of central/eastern MO into southern IL and
    far western KY

    Concerning...Severe Thunderstorm Watch 479...480...

    Valid 110026Z - 110200Z

    The severe weather threat for Severe Thunderstorm Watch 479, 480
    continues.

    SUMMARY...Small storm clusters capable of producing wind damage may
    continue through the evening.

    DISCUSSION...At 0015 UTC, a small but long-lived storm cluster is
    moving along I-70 between Columbia and St. Louis. Some wind damage
    was reported in the Columbia area, and strong inbound velocities are
    currently observed from the KLSX radar. This cluster may continue
    propagating along a surface theta-e gradient, with rich moisture
    (dewpoints in the 70s F and PW above 2 inches), moderate buoyancy,
    and sufficient low-level flow and deep-layer shear supporting a
    continued damaging wind threat as this cluster approaches the
    Mississippi River.

    To the east, another storm cluster across southwest IL may also
    continue to propagate along the theta-e/buoyancy gradient, posing a
    threat of wind damage into a larger portion of southern IL through
    the evening.

    Farther south, a measured severe gust was recently observed near
    West Plains in south-central MO, near another developing storm
    cluster. Deep-layer shear is weaker in this area, but strong
    downstream buoyancy may allow for modest upscale growth and a
    continued wind damage threat this evening into southeast MO (as
    depicted by some recent HRRR runs).
