    Areas affected...portions of southern Coastal California

    Concerning...Severe Thunderstorm Watch 622...

    Valid 141242Z - 141415Z

    The severe weather threat for Severe Thunderstorm Watch 622
    continues.

    SUMMARY...A damaging gust may occur this morning.

    DISCUSSION...A pronounced mid-level trough and an associated 80+ kt
    mid-level jet streak is currently overspreading the LA Basin, with
    60 F surface dewpoints impinging on the shoreline. Intense dynamic
    forcing currently supports a strong vertical wind field and
    accompanying shear profile over southern CA, where a low-topped
    confluence band is currently progressing. Some of the stronger
    showers in the region have supported damaging gusts over the past
    couple of hours, including a measured severe gust and wind damage
    report in Ventura/Los Angeles counties. The current thinking is that
    the potential for an additional damaging or perhaps severe gust will
    remain in place through the morning hours as the low-topped
    convective band continues to take advantage of scant buoyancy in the
    region.
