    Areas affected...Southern and Central Kansas...Texas and Oklahoma Panhandles...Western and Central Oklahoma

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

    Valid 230207Z - 230400Z

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

    SUMMARY...A wind damage threat will continue as a squall-line moves east-southeastward across parts of the southern and central Plains.
    A new severe thunderstorm watch will be issued shortly for areas to
    the east of weather watch 201.

    DISCUSSION...The latest radar imagery shows a linear MCS from
    southern Kansas extending southwestward into western Oklahoma and
    the eastern Texas Panhandle. The MCS is being supported by a
    shortwave trough evident on water vapor imagery over the central
    Plains and southern High Plains. Ahead of the shortwave trough, a 40
    to 50 kt low-level jet will strengthen across the southern Plains
    enabling the linear MCS to be maintained late this evening into the
    overnight. The greatest wind damage potential should be over
    northern and central Oklahoma along the leading edge of the fastest
    moving line segments. However, there remains some potential that a
    severe threat could impact parts of southern Oklahoma where surface temperatures and the resulting instability was greater. Isolated
    large hail will also be possible with rotating cell elements along
    the squall-line.
