    Areas affected...southeast Colorado through southwest Kansas

    Concerning...Tornado Watch 175...

    Valid 152317Z - 160015Z

    The severe weather threat for Tornado Watch 175 continues.

    SUMMARY...A relatively small window will exist through mid evening
    for brief isolated tornadoes from a portion of southeast Colorado
    through southwest Kansas.

    DISCUSSION...Early this evening a stationary boundary extends
    through southwest Kansas into southeast Colorado. Dewpoints are
    generally in the upper 50s to around 60 F in vicinity of this
    boundary contributing to somewhat lower LCLs and up to 2000 J/kg
    MLCAPE. Storms will continue spreading eastward off the higher
    terrain, and other storms may initiate on the boundary. Effective
    bulk shear around 35 kt will promote both multicell and marginal
    supercell structures, and some increase in 0-2 km hodograph size
    will occur as the low-level jet strengthens this evening. The
    primary threat for a few brief tornadoes is expected to occur as
    storms develop along or move east and interact with the boundary
    where low-level vorticity will be maximized.
