    Upper level ridging building over the region through
    the weekend. Low level onshore flow will continue through
    Saturday then weaken. Expect mainly VFR conditions this evening
    as strong June sunshine dissipates the marine layer clouds. Later
    tonight expect MVFR cigs 1500-2000 feet to develop. The cloud
    layer will be shallower Sat so expect clouds to become SCT
    earlier than today.

    MVFR cigs around 1500 feet after 10Z Sat. Cigs should dissipate
    by 20Z Saturday.
