    Mesoscale Discussion 0781
    NWS Storm Prediction Center Norman OK
    0219 PM CDT Mon Jun 18 2018

    Areas affected...Central/northern Kansas

    Concerning...Severe potential...Watch unlikely

    Valid 181919Z - 182115Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Storms are expected into the evening and isolated storms
    could become severe. Hail and strong winds are the primary threats
    with the strongest storms.

    DISCUSSION...An upper-level shortwave passing over the Plains per
    satellite imagery is helping to provide forcing for ascent.
    Additionally, ample low-level moisture (surface dewpoints upper 60s
    to low 70s; mean mixing ratios of 13-15 g/kg) and strong diabatic
    heating (surface temperatures in the 90s) have destabilized
    lower-levels resulting in thunderstorm development. Shear and flow
    aloft are weak, but the atmosphere is strongly buoyant (MLCAPE 2000+
    J/kg). Storms should continue to form mostly along a southwest to
    northeast oriented diffuse surface trough. Isolated storms could
    become severe with hail and strong wind gusts (DCAPE 1000+ J/kg) as
    the primary threats.
