    Areas affected...South-central Kansas...Eastern Texas and Oklahoma Panhandles...Western and Central Oklahoma

    Concerning...Severe Thunderstorm Watch 199...200...201...

    Valid 230012Z - 230215Z

    The severe weather threat for Severe Thunderstorm Watch 199, 200,
    201 continues.

    SUMMARY...The wind damage threat will likely continue with a linear
    MCS moving east-southeastward across parts of the central and
    southern Plains this evening. A brief tornado or an isolated large
    hail threat will also exist with the stronger portions of the line.

    DISCUSSION...A linear MCS is continuing to organize across the
    southern and central High Plains early this evening. The MCS is
    expected to enter the mature phase over the next couple of hours as
    it moves east-southeastward across south-central Kansas, the eastern
    Texas Panhandle and into northwest Oklahoma. Over the last hour, the
    line has accelerated and the faster moving segments within the line
    are moving at about 55 knots. This speed of movement will make wind
    damage likely along the leading edge. A 69 knot gust was measured at
    Dodge City at 7:02 CDT. The strongest part of the MCS is expected to
    move across southern Kansas, the northeastern Texas Panhandle and
    northwestern Oklahoma where the combination of shear and instability
    is maximized. The low-level jet will increase across the southern
    Plains also aiding development with the MCS. A weather watch may
    need to be considered to the east of severe thunderstorm watch 201
    later this evening.
