    Mesoscale Discussion 1196
    NWS Storm Prediction Center Norman OK
    1104 AM CDT Sun Jun 08 2025

    Areas affected...portions of the OK/TX Panhandles into western OK

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

    Valid 081604Z - 081800Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Elevated thunderstorms may produce isolated large hail and
    strong gusts through early afternoon before more intense convection
    develops by mid/late afternoon.

    DISCUSSION...Visible satellite trends have shows towering cumulus
    and isolated thunderstorm development late this morning in a
    low-level warm advection regime. Strong capping is still in place
    across the region, with temperatures still mainly in the 70s in the
    OK/TX Panhandles, through strong heating is occurring and
    temperatures have warmed into the mid/upper 80s across western OK.
    This initial thunderstorm activity will remain elevated, but could
    become surface based over the next few hours via mixing and
    additional heating/moistening. Regardless, this convection is
    developing within a strong MUCAPE gradient near the western OK/TX
    Panhandle border, and within 30-40 kt effective shear magnitudes.
    Very steep midlevel lapse rates are also in place across the region.
    As a result, even this initially elevated convection could pose a
    risk for large hail.=20

    The need for a watch with this early activity is uncertain and
    trends will be monitored. Additional, more intense and surface-based
    convection is still expected to develop by mid/late afternoon and
    will be addressed in subsequent MCDs as the risk evolves over time.
