    Mesoscale Discussion 1583
    NWS Storm Prediction Center Norman OK
    0454 PM CDT Sun Jul 06 2025

    Areas affected...Parts of southern Kansas...northern Oklahoma...and
    the far eastern TX/OK Panhandles

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

    Valid 062154Z - 070000Z

    Probability of Watch Issuance...20 percent

    SUMMARY...Sporadic severe wind gusts and isolated large hail are
    possible with the stronger storms into this evening. A watch is not
    currently expected, though convective trends are being monitored.

    DISCUSSION...Widely scattered outflow-dominant thunderstorms are
    evolving along a stalled surface boundary from southern KS into
    northern OK. Steep midlevel lapse rates atop a warm/moist boundary
    layer are yielding strong surface-based buoyancy ahead of these
    storms. While the environment is favorable for sporadic severe
    downbursts and isolated large hail, generally weak deep-layer
    flow/shear limits confidence in storm organization/longevity.
    Therefore, a watch is not currently expected, though convective
    trends are being monitored.
