    Coastal stratus is expected to retreat to the beaches
    by this afternoon resulting in widespread VFR conditions across
    northwest Oregon and southwest Washington. Expect high end IFR to
    low end MVFR stratus to return to the coast towards 03z Sunday,
    but skeptical it will reach as far inland as the Portland metro
    by daybreak on Sunday.
    
    KPDX AND APPROACHES...A typical summertime low level northwesterly
    flow pattern will produce predominantly VFR conditions through
    18z Sunday. There is a chance of MVFR cigs between 13-17z Sunday
    as marine stratus attempts to move up the Columbia River. /Neuman
