    Areas affected...Eastern KS into western/northern MO and
    west-central IL

    Concerning...Severe Thunderstorm Watch 38...

    Valid 140730Z - 140900Z

    The severe weather threat for Severe Thunderstorm Watch 38
    continues.

    SUMMARY...Hail and localized severe gusts will remain possible
    overnight. Eventual downstream watch issuance is possible, depending
    on convective trends.

    DISCUSSION...At 0730 UTC, multiple storm clusters are ongoing from
    eastern KS into western/northern MO and western IL. The most
    vigorous ongoing cluster (based on radar and satellite trends) is
    located across east-central/southeast KS, where a strong
    mid/upper-level jet is impinging upon moderate to strong elevated
    buoyancy (MUCAPE of greater than 2000 J/kg). Steep midlevel lapse
    rates, cold temperatures aloft, and sufficient effective shear will
    support a hail threat with the strongest storms in this region,
    though a possible transition to more of a linear mode may temper
    hail potential to some extent. Also, despite the presence of some
    low-level stability, localized severe gusts will continue to be
    possible with this cluster, as indicated by a recent 59 mph gust
    near Eureka, KS.=20

    Other elevated storm clusters are ongoing in an east-west oriented
    band from northeast KS into northern MO. Severe gusts have recently
    been observed at Kirksville and Moberly, MO, and moderate elevated
    buoyancy will continue to support a threat of isolated hail and
    strong gusts as these clusters move eastward.=20

    With time, a larger QLCS could evolve and accelerate eastward, as
    the southeast KS cluster merges with convection and a related
    outflow boundary to its north and northeast. This could lead to some
    eventual increase in severe potential to the east of WW 38.
    Depending on convective trends through the overnight hours, eventual
    downstream watch issuance is possible.
