    Areas affected...Parts of southwest Kansas

    Concerning...Tornado Watch 287...291...

    Valid 190227Z - 190330Z

    The severe weather threat for Tornado Watch 287, 291 continues.

    SUMMARY...A highly favorable and localized tornado corridor is
    evident in parts of southwest Kansas.

    DISCUSSION...A supercell has recently intensified at the nose of the strong/extreme surface-based instability over southwest KS. Here,
    the VNX/DDC VWPs are sampling a 40-50 kt low-level jet -- which is
    contributing to 350-400 m2/s2 0-500m SRH. This very high helicity
    and strong/extreme instability will favor a localized corridor for
    tornadoes -- some of which may be strong/intense if storms can
    remain surface-based.
