Aviation Forecasts Discussions (AFD) INFO

(EXTRACTED FROM FXUS61 KLWX 241933)


    Low clouds (generally IFR) have persisted all day. Models
    actually picked up on the ceilings rising to MVFR at BWI/MTN but
    I didn't believe it. Given that model performance, I'll give the
    models additional credit for the rest of the TAF period, and
    the guidance has been trending away from dense fog tonight due
    to a little mixing and the expected rain. However, it retains
    low (IFR or LIFR) ceilings throughout, especially once the rain
    moves back in after a lull late this afternoon and evening.
    
    Winds will shift out of the south after daybreak, and then turn
    southwest and west through the day. Rain generally ends by early
    afternoon with ceilings rising as the front passes.
    
    The forecast period beyond the TAF through Tuesday should
    feature mid-high clouds at most; yielding VFR conditions.
    
    High pressure on Wednesday will bring VFR conditions to start the
    day. Clouds increase during the afternoon...and there could be some
    MVFR cigs in showers late in the day. As low pressure east just
    north of the Mason-Dixon line...expect IFR to LIFR cigs and vsbys in
    precip/fog on Thur.
