    Areas affected...Southwest and South-central Missouri

    Concerning...Tornado Watch 153...

    Valid 270322Z - 270515Z

    The severe weather threat for Tornado Watch 153 continues.

    SUMMARY...A tornado threat is expected to continue for several more
    hours into the early overnight period across parts of southwest and south-central Missouri.

    DISCUSSION...On water vapor imagery, a vigorous shortwave trough is
    evident over the northern Ozarks. Near this feature, scattered
    strong to severe thunderstorms are ongoing. Ahead of and to the
    south of the storms, moderate instability is analyzed by the RAP in
    southwest Missouri. Over the top of the unstable airmass, mid-level
    flow is westerly at 40 knots. This is creating shear favorable for
    supercells. In addition, the RAP is showing a 30 to 40 knot
    low-level jet located over west-central and southwest Missouri. The
    WSR-88D VWP at Springfield, Missouri has a looped hodograph with 0-3
    km storm-relative helicity near 650 m2/s2. This will continue
    support a tornado threat with supercells. Large hail and wind damage
    will also be likely with supercells.
