    Mesoscale Discussion 1107
    NWS Storm Prediction Center Norman OK
    1142 PM CDT Fri Jun 25 2021

    Areas affected...Southeast KS...northeast OK

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

    Valid 260442Z - 260545Z

    Probability of Watch Issuance...20 percent

    SUMMARY...An isolated severe wind and a brief tornado threat may
    persist through about 07Z across mainly southeast KS into a portion
    of northeast OK.

    DISCUSSION...A storm cluster intensified over south-central KS, to
    the south of an MCV in central KS, as outflow from a largely
    decaying cluster in north-central OK merged with the remnant outflow
    from the decaying MCS that was in southeast OK and southwest MO.
    Organization of the cluster with a couple of brief mesovorticities
    were noted earlier near Wichita. Potential will exist for transient mesovorticities capable of producing severe wind gusts and a brief
    tornado given a rather enlarged low-level hodograph amid 40-kt 1 km
    AGL southwesterlies sampled by the INX VWP atop the remnant outflow
    boundary. Overnight, stronger low-level flow will be increasingly
    focused across the southern High Plains (reference MCD 1106), and
    strengthening MLCIN across much of OK both suggest that the overall
    severe threat will remain temporally and spatially limited farther
