    Concerning...Severe Thunderstorm Watch 417...

    Valid 150946Z - 151145Z

    The severe weather threat for Severe Thunderstorm Watch 417
    continues.

    SUMMARY...Some risk for strong to severe gusts and severe hail
    probably will continue beyond daybreak with thunderstorms developing
    into and across parts of western through southern Oklahoma.=20
    However, it is not clear that an additional severe weather watch
    will be needed.

    DISCUSSION...Within a generally weak large-scale flow regime,
    convectively augmented mid-level troughing continues to slowly dig south-southeastward across parts of southeastern Kansas and eastern
    Oklahoma. Aided by persistent vigorous thunderstorm development,
    supported by lower/mid-tropospheric warm advection above the western
    flank of a composite outflow, the outflow has been slowly spreading west-southwestward across the Interstate 35 corridor of north
    central Oklahoma. This is likely to continue into
    western/southwestern Oklahoma through and beyond daybreak.

    As the nocturnal low-level jet weakens, forcing to overcome
    mid-level inhibition and maintain convective development in the
    presence of moderate potential instability remains unclear. It is
    possible that lift along an intersecting outflow emerging the Texas
    Panhandle could maintain a corridor of vigorous thunderstorm
    development, but this is not certain based on model output.=20=20

    Regardless, barring more substantive cold pool strengthening with
    the Texas Panhandle cluster than currently appears probable, there
    is little to suggest potential for a substantive increase in severe
    weather into mid morning. However, a couple of locally strong to
    severe gusts remain possible, along with some continuing risk for
    severe hail in stronger cells.
