    Mesoscale Discussion 2338
    NWS Storm Prediction Center Norman OK
    0256 PM CDT Wed Sep 30 2026

    Areas affected...portions of western Texas

    Concerning...Severe potential...Watch possible

    Valid 301956Z - 302200Z

    Probability of Watch Issuance...40 percent

    SUMMARY...At least a few severe gusts and a couple instances of hail
    are possible with the stronger storms that can develop over the next
    several hours. Assuming storms can appreciably increase in both
    coverage and intensity, a Severe Thunderstorm Watch may be needed,

    DISCUSSION...A surface low continues to track northeast along the
    KS/OK Panhandle border area, with a weak surface trough extending
    through western TX and a cold front trailing the surface low into
    eastern NM. Ahead of the surface cold front and lee trough, surface temperatures have warmed into the upper 80s to 90 F amid upper 50s
    to upper 60s F dewpoints. RAP forecast soundings suggest a dry
    boundary layer is in place, potentially extending to over 700 mb in
    altitude. Visible satellite and MRMS mosaic radar data depict
    developing storms, and as these storm mature, they should become
    multicellular initially (given 20-30 kts of effective bulk shear).
    Given nearly unidirectional tropospheric flow aligned roughly
    parallel to the lee trough, convection should quickly become linear
    in nature. As these linear segments overspread the dry boundary
    layer, a few severe gusts may occur, along with an instance or two
    of hail.
