    Mesoscale Discussion 1033
    NWS Storm Prediction Center Norman OK
    0738 AM CDT Wed Jun 14 2023

    Areas affected...Parts of southern OK/north TX into the ArkLaTex

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

    Valid 141238Z - 141445Z

    Probability of Watch Issuance...40 percent

    SUMMARY...Supercell development is possible later this morning,
    though timing remains uncertain. Watch issuance is possible.

    DISCUSSION...At 1230 UTC, increasing cumulus is noted on visible and
    IR imagery across northeast TX/southeast OK, which may be the
    precursor to more robust elevated thunderstorm development. Regional
    12Z soundings depict very favorable instability and shear across the
    region, with MUCAPE in excess of 3000 J/kg, steep midlevel lapse
    rates, and strong effective shear in excess of 60 kt. This is
    resulting in a conditionally favorable environment for supercells,
    with an attendant threat of very large hail.=20

    However, uncertainty remains regarding the timing and coverage of
    development through the morning, with stronger large-scale ascent
    likely focused north of this region. While a watch will likely be
    needed at some point later today across parts of the MCD area, the
    short-term potential remains uncertain. Watch issuance is currently
    considered possible through 15 UTC, though it will become likely if
    there is any indication of robust elevated supercell development.
