    Mesoscale Discussion 1552
    NWS Storm Prediction Center Norman OK
    0306 PM CDT Tue Oct 09 2018

    Areas affected...Eastern Kansas...western Missouri and northwestern
    Arkansas

    Concerning...Tornado Watch 403...404...

    Valid 092006Z - 092130Z

    The severe weather threat for Tornado Watch 403, 404 continues.

    SUMMARY...Thunderstorms developing across the region may pose a risk
    for tornadoes and localized strong wind gusts through 6-7 PM CDT

    DISCUSSION...The slowly deepening surface low center appears in the
    process of developing to the east/northeast of Salina KS, and likely
    to continue northeastward toward the Falls City NE area through
    23-00Z. Large clockwise curved low-level hodographs are focused
    within the warm sector in close proximity to the low, and along/to
    the immediate east of the arcing convective band now advancing into
    the Kansas City metro area.

    A number of cells within the convective band, as well as along a
    remnant convective boundary extending northeastward (roughly along
    the Interstate 35 corridor) are slowly organizing and intensifying
    in the presence of high boundary layer moisture content (surface dew
    points now near 70f) and weak to modest CAPE (up to 1000 J/kg).
    This environment appears conducive to occasional continuing
    development of low-level mesocyclones, accompanied by a risk for
    tornadoes and/or locally damaging wind gusts, and will gradually
    shift northeast of the Kansas City area toward the Missouri/Iowa
    border area through early evening.
