    VFR conditions across most of the area this afternoon
    as low clouds continue to scatter, but MVFR cigs do remain in the
    far southern parts of the Willamette Valley (around KEUG).
    Meanwhile, some showers are developing over the WA and N OR
    Cascades, and these may continue to drift into parts of Portland
    metro area this afternoon and evening. Otherwise, expect a return
    of low clouds to the coastal areas and southern half of the
    interior lowlands tonight. Guidance indicates that clouds may
    build up along the Cascades foothills and perhaps into the
    Portland metro terminals, but confidence is low to moderate in
    this scenario.
    
    KPDX AND APPROACHES...VFR conditions this afternoon. Some showers
    or possibly a thunderstorm may develop around the terminal
    through around 04z, which could result in lightning and/or brief
    MVFR conditions. A lower MVFR cloud deck may develop south and east
    of the terminal late overnight (after 13z) and could build back
    into the terminal, but confidence in this remains moderate at
    best.	 Cullen
