    Mesoscale Discussion 0891
    NWS Storm Prediction Center Norman OK
    0229 PM CDT Fri May 29 2026

    Areas affected...Parts of the TX South Plains/Permian Basin vicinity

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

    Valid 291929Z - 292130Z

    Probability of Watch Issuance...60 percent

    SUMMARY...Severe storms may develop by 4-5 PM CDT, with a threat of
    hail and severe gusts. Watch issuance is possible.

    DISCUSSION...Relatively strong heating is underway across parts of
    west TX this afternoon, though some areas of mid/upper-level clouds
    persist. Low-level south/southeasterly flow to the east of a weak
    surface trough is maintaining sufficient low-level moisture for
    moderate destabilization, with MLCAPE increasing to near/above 1500
    J/kg across parts of the TX South Plains and Permian Basin.
    Decreasing CINH and a subtle midlevel shortwave trough near the
    TX/NM border will support scattered thunderstorm development by late
    afternoon. An approaching mid/upper-level subtropical jet maximum
    will lead to strengthening deep-layer shear (with effective shear of
    40+ kt), and a few organized cells or clusters may evolve with time.

    Isolated large hail will be possible, including conditional
    potential for 2+ inch diameter hail if any sustained supercells
    develop. Relatively deep mixing and steep low-level lapse rates will
    encourage increasing outflow with time, with an attendant threat of
    at least isolated severe gusts (potentially 75+ mph). Issuance of
    one or more watches is possible later this afternoon in order to
    address these threats.
