    Areas affected...parts of southeastern Kansas...northeastern Oklahoma...southwest through east central Missouri into central
    Illinois

    Concerning...Severe potential...Watch unlikely=20

    Valid 120359Z - 120600Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Stronger thunderstorm development has begun to weaken. As
    this continues, peak wind gusts along the associated gust front are
    likely to follow suit.

    DISCUSSION...Notable surface pressure rises (up to 2-4+ mb 2-hourly
    in 03Z surface observations), associated with strengthening
    convective cold pools, have supported a period of locally strong to
    severe northwesterly surface gusts and southeastward propagation of
    stronger convection, in the presence of otherwise modest
    southwesterly deep-layer mean flow. However, increasing inhibition
    for seasonably moist, potentially unstable parcels within the
    southeasterly low-level updraft inflow has begun to contribute to
    substantive weakening of convection. As this continues over the
    next few hours, the risk for localized damaging wind gusts is
    expected to continue to wane.
