    Areas affected...Oklahoma...Western Arkansas

    Concerning...Severe Thunderstorm Watch 200...202...

    Valid 230409Z - 230615Z

    The severe weather threat for Severe Thunderstorm Watch 200, 202
    continues.

    SUMMARY...A wind damage threat will continue across much of Oklahoma
    over the next few hours, reaching western Arkansas after midnight. A
    new weather watch will likely be necessary to the east of severe
    thunderstorm watch 202 as the line approaches the eastern edge of
    the watch.

    DISCUSSION...The latest radar imagery shows a mature fast-moving
    linear MCS across central and southwestern Oklahoma. The linear MCS
    is moving east-southeastward at about 60 kt and is forecast to
    approach the eastern edge of severe thunderstorm watch 202 by around
    0530Z. The 60 kt movement will make wind damage likely along the
    leading edge of the MCS. Damaging wind gusts of greater than 70 mph
    will be possible with the stronger parts of the line. Ahead of the
    MCS, the RAP is analyzing moderate instability across southeastern
    Oklahoma into southwestern Arkansas suggesting the MCS will track
    and develop more on the southern end. This should take the line of
    storms across southeastern Oklahoma and into southwestern Arkansas.
