    Mesoscale Discussion 1296
    NWS Storm Prediction Center Norman OK
    0514 PM CDT Wed Jun 24 2026

    Areas affected...portions of far southern Oklahoma into far northern Texas...extreme southwestern Arkansas and extreme northwestern
    Louisiana

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

    Valid 242214Z - 242345Z

    Probability of Watch Issuance...20 percent

    SUMMARY...An isolated severe wind/hail risk exists along a
    baroclinic boundary under the condition that storms can initiate and
    organize.

    DISCUSSION...A quasi-stationary baroclinic boundary currently
    resides just north of the Red River along much of far southern OK.
    Despite weak synoptic forcing for ascent, extreme buoyancy (4000+
    J/kg MLCAPE) and minimal MLCINH with 40+ kts of effective bulk shear
    is coinciding with the boundary per 21Z mesoanalysis. As such, any
    storm that manages to develop and sustain itself will have the
    potential to produce severe wind/hail or perhaps a tornado. A storm
    has recently initiated over Atoka County, OK, suggesting that
    surface-based heating is strong enough to support additional
    isolated attempts at convective initiation along this boundary over
    the next several hours. The severe threat should remain isolated
    given overall lack of deep-layer ascent.
