    Mesoscale Discussion 1672
    NWS Storm Prediction Center Norman OK
    0912 PM CST Fri Nov 30 2018

    Areas affected...Southeast KS...Southwest MO

    Concerning...Severe potential...Watch possible

    Valid 010312Z - 010515Z

    Probability of Watch Issuance...40 percent

    SUMMARY...The severe threat will increase late this evening ahead of
    the primary thunderstorm band. Watch issuance is possible.

    DISCUSSION...Primarily elevated convection is ongoing across
    southeast KS and southwest MO as of 03Z. While steep midlevel lapse
    rates and sufficient effective shear will support a localized hail
    threat in the short term with the strongest cores, a somewhat
    greater severe threat is expected later this evening associated with
    the ongoing QLCS across central into northeast OK. This QLCS should
    be maintained through much of the night as it moves northeastward in
    advance of the strong mid/upper trough and surface low currently
    moving into central OK. Some severe wind threat will likely spread
    into southeast KS/southwest MO with time, though this may be
    mitigated to some extent by a stable near-surface layer, since the
    primary warm front is expected to generally remain south of this
    area. A brief tornado or two cannot be ruled out across far
    southeast KS/southwest MO given strong low-level shear, though
    unfavorable low-level stability should tend to mitigate the tornado
    threat as well. Watch issuance is possible within the next 1-2 hours
    if the ongoing QLCS across OK maintains its intensity.
