    Mesoscale Discussion 1750
    NWS Storm Prediction Center Norman OK
    0910 PM CDT Mon Jul 21 2025

    Areas affected...West-central into central South Dakota and far
    south-central North Dakota

    Concerning...Severe potential...Watch possible=20

    Valid 220210Z - 220415Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Though uncertain, some increase in storm
    intensity/coverage is possible this evening. Convective trends will
    be monitored for a possible watch.

    DISCUSSION...A small cluster of storms northeast of the Black Hills
    has recently shown some modest intensification. Another storm has
    also developed east of the Black Hills. This is likely in response
    to a strengthening low-level jet. MLCAPE is still near or above 4000
    J/kg ahead of this activity and effective shear is sufficient for
    organized storms. However, MLCIN is also starting to slowly increase
    as well. With little upper-level support, it is not clear whether
    storms will maintain intensity or how much coverage will increase
    this evening. A watch is possible, but it will depend on convective
    trends in intensity/upscale growth.
