Aviation Forecasts Discussions (AFD) INFO

(EXTRACTED FROM FXUS66 KPQR 171757)


    Warm front affecting the area is bringing primarily
    MVFR cigs to the northern terminal and the coast along with
    periodic MVFR vsbys and very occasional IFR vsbys under heavier
    drizzle. VFR conditions generally dominate interior south of a
    KMMV to KUAO line. Expect conditions to improve somewhat as the
    warm front crosses the area over the next couple hours. Then will
    see a weak cold front drop south this evening and overnight with
    conditions falling back into widespread MVFR. Expect IFR (maybe
    LIFR) at KONP as moist low level onshore flow develops overnight.
    IFR cigs also possible at KEUG but not as confident yet.
    
    PDX AND APPROACHES...Some improvement expected into low end VFR
    after the warm front crosses the area today, but still expect
    cigs AOB 040 to limit visual approaches. Cigs fall back to the
    020-030 range tonight as weak cold frontal rain arrives. Impacts
    remain through the morning push. /JBonk
