    Mesoscale Discussion 0455
    NWS Storm Prediction Center Norman OK
    0923 PM CDT Wed Apr 16 2025

    Areas affected...Portions of central/eastern Kansas

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

    Valid 170223Z - 170430Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Isolated large hail and potentially strong/damaging
    surface gusts are possible as elevated storms move eastward this
    evening.

    DISCUSSION...Moisture return continues this evening in the
    southern/central Plains. Dewpoints have risen into the mid 50s F in south-central Kansas. Even with this increase in low-level moisture,
    cooling surface temperatures have contributed to slowly increasing
    CIN. With the low-level jet increasing within the region (around 50
    kts per KVNX and KICT VAD data), convection has increased in
    coverage and intensity near and east of Dodge City. A continued
    increase in 850 mb winds through the evening will support additional
    convective development and potentially some clustering as activity
    moves into parts of eastern Kansas. There is some possibility that
    additional storms can develop north of the current activity, but
    confidence is low.

    The observed soundings at Dodge City and Topeka showed steep
    mid-level lapse rates (around 8 C/km). The stronger elevated storms
    would be capable of large hail given over 50 kts of effective shear.
    If storms can cluster later this evening, there would be some
    potential for a strong/damaging surface gust to occur as well.
