    Concerning...Severe Thunderstorm Watch 95...

    Valid 040433Z - 040530Z

    The severe weather threat for Severe Thunderstorm Watch 95
    continues.

    SUMMARY...Severe gusts remain possible with an expansive MCS over
    the next few hours.

    DISCUSSION...A persistent, elongated MCS has materialized from
    southwest MO to south-central OK over the past few hours, with a
    progressive embedded bowing feature continuing across east-central
    OK. This bow has a history of severe gusts, and while the bow has
    diminished a bit in intensity, severe gusts remain possible given
    1000+ J/kg MLCAPE and 35 kts of effective bulk shear remaining in
    place. A severe gust may also occur wherever a additional bowing
    structures may materialize, from southwestern MO to southern OK.
    However, the greatest short-term severe risk remains with the
    progressive bow.
