    Mesoscale Discussion 0633
    NWS Storm Prediction Center Norman OK
    0102 PM CDT Sun Jun 03 2018

    Areas affected...parts of western and central New Mexico and into
    far West Texas

    Concerning...Severe potential...Watch likely

    Valid 031802Z - 032000Z

    Probability of Watch Issuance...80 percent

    SUMMARY...Severe risk is expected to continue increasing across
    portions of New Mexico and far West Texas over the next few hours.
    WW will likely be needed.

    DISCUSSION...Latest visible satellite imagery and radar loops show
    convection increasing at this time over parts of western New Mexico,
    as ascent associated with the Four-Corners-area vort max overspreads
    this area.

    Strong diurnal heating across this region has helped boost
    mixed-layer CAPE, with near 500 J/kg values in northwest New Mexico
    increasing to near 2000 J/kg over south-central New Mexico and far
    West Texas, where greater boundary-layer dewpoints are observed.
    Continued heating/destabilization and existing large-scale ascent
    suggests continued convective increase over the next several hours.

    Along with ample CAPE, moderately strong southwesterly mid-level
    flow is indicated atop the area per area VWPs -- contributing to veering/increasing winds with height supportive of
    organized/rotating storms. CAM runs suggest isolated storm mode
    initially, with eventual upscale growth later this afternoon and
    evening into one or more eastward-moving MCSs. While resulting
    severe risk would likely trend toward primarily wind damaging in
    this scenario, the initial/more cellular storms will likely prove
    capable of producing hail, in addition to locally damaging winds. A
    tornado or two may also occur with initial/rotating storm mode.
