    Mesoscale Discussion 1692
    NWS Storm Prediction Center Norman OK
    0529 PM CDT Wed Jul 16 2025

    Areas affected...Central and southwest Kansas

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

    Valid 162229Z - 170000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Thunderstorm development along and to the immediate cool
    side of the front is expected through late evening. Isolated
    downburst winds and large hail may occur, but limited storm
    organization suggests a watch is unlikely.

    DISCUSSION...Surface temperatures have warmed into the low-mid 90s
    along a stalled front across central/southwest KS, where strong
    buoyancy (MLCAPE > 3000 J/kg) and minimal convective inhibition
    coincide. Ascent atop the frontal surface should support scattered thunderstorms through late evening, where steep midlevel lapse rates
    will favor some potential for isolated large hail and strong-severe
    outflow gusts. However, storm intensity/duration should both be
    limited by relatively weak vertical shear (only modest enhancement
    to low-level shear on the cool side of the front). Thus, a watch
    will likely not be needed.
