    Areas affected...portions of northern California...north and central Nevada...and western Utah

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

    Valid 061912Z - 062115Z

    Probability of Watch Issuance...5 percent

    SUMMARY...Thunderstorms may produce hail and gusty winds through the
    afternoon.

    DISCUSSION...Thunderstorm development has been noted across portions
    of northern California, north-central Nevada, and northern Utah in
    the last hour. Temperatures have warmed quickly with little cloud
    cover through the morning. Modifying the 12z soundings from LKN and
    SLC produces a deeply mixed boundary layer with steep lapse rates
    through the profile. Surface objective analysis indicates MLCAPE
    around 500 J/kg amid modest deep layer shear around 30-35 kts. This
    environment will favor multi-cell clusters, with potential for a few
    instances of severe wind and hail. Given the lack of deeper
    moisture, the spatial extent of this threat will likely remain too
    small for watch issuance.
