    Mesoscale Discussion 2262
    NWS Storm Prediction Center Norman OK

    Areas affected...Central/North-Central TX

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

    Valid 251802Z - 252000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated damaging gusts and a brief tornado or two are
    possible across central/north-central Texas this afternoon.

    DISCUSSION...Convective outflow, which currently stretches from
    Young County TX southward/south-southwestward to Kimble and Edwards
    County TX, continues to gradually push eastward into
    north-central/central TX. Updraft intensity in the thunderstorms
    ongoing along this outflow boundary has remained relatively constant
    over the past two hours, with downstream airmass destabilization
    tempered by widespread cloud cover thus far. Northern portion of the
    line has recently shown a bit more eastward propagation over the
    past half hour as well as some sharpening of the reflectivity
    gradient along its leading edge. A mesoscale convective vortex may
    be developing in this vicinity of the line, which could be
    contributing to this increased forward propagation, and a few
    damaging gusts are possible along this portion of the line as it
    continues eastward.

    Farther south into central TX, convection within this portion of the
    line is weaker and less organized along the leading edge of the
    outflow, with an increasingly disorganized, banded structure with
    southern extent. However, deep convection has been realized within
    the warm sector ahead of the line over Hamilton County. Deep-layer
    shear profiles support the potential for supercells, particularly
    with any more discrete development, with low-level curvature
    moderately supportive of tornadoes as well. Modest buoyancy will be
    limiting factor, but a low-probability potential for a brief tornado
    or two exists.
