    Mesoscale Discussion 0375

    0348 PM CDT Fri Apr 10 2026

    Areas affected...portions of central California

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

    Valid 102048Z - 102245Z

    Probability of Watch Issuance...5 percent

    SUMMARY...An instance of hail or perhaps a brief tornado may
    accompany the stronger storms that manage to develop this afternoon.
    However, the severe threat should remain sparse.

    DISCUSSION...Widespread clouds, rainfall, and occasional
    thunderstorms have overspread the central and northern CA Valley
    region through much of the day, inhibiting destabilization to a
    degree. However, some breaks in the clouds have allowed surface
    temperatures to reach into the mid 60s to low 70s F, amid 50 F
    dewpoints over the lower Sacramento Valley into the San Joaquin
    Valley. 20Z mesoanalysis depicts MLCAPE exceeding 500 J/kg, with
    just over 150 J/kg CAPE in the 0-3 km layer. With continued heating/destabilization, multicells and low-topped supercells should
    develop. Given some low-level vertically oriented vorticity present
    in the Valley areas, any supercell that can become sustained may
    ingest this vorticity and produce a brief tornado, in addition to
    some hail. Nonetheless, the severe threat will be quite isolated at
    best, so a WW issuance is not expected.
