    Mesoscale Discussion 1456

    0107 PM CDT Thu Jun 26 2025

    Areas affected...Southern lower MI into parts of IN/OH...western
    PA...northern WV

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

    Valid 261807Z - 262000Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Storms with localized damaging winds are possible this
    afternoon.

    DISCUSSION...Multiple storm clusters are ongoing early this
    afternoon across southern lower MI, with other recent development
    into northeast OH and northern IN. The southern lower MI storms are
    accompanied by gradually expanding outflow, which will eventually
    move into parts of northeast IN and northern OH. Additional storm
    development may occur near this outflow this afternoon as it spreads east-southeastward. Deep-layer shear is weak, but modest
    west-northwesterly flow in the 850-700 mb layer may support
    occasional loosely organized clusters. A 44 kt gust was recently
    observed in Toledo, OH, and strong buoyancy and steep low-level
    lapse rates will continue to support a threat of strong gusts and
    localized damaging wind through the afternoon.=20

    Farther south, deep-layer shear is even weaker into parts of central
    IN, central/southern OH, and southwest PA. However, a favorable
    downburst environment is in place across this region, with strong
    buoyancy, relatively large PW, and steepening low-level lapse rates.
    A threat for locally damaging wind will accompany the strongest
    storms.
