    For the 06Z TAFs...
    
    The main weather concerns will be the timing of low CIGS and fog
    which is likely to arrive across the area by this evening.
    
    Saturday should start out VFR, but later in the day expect
    increasing warm moist air to allow a lower stratus deck to
    gradually shift northward over the area. While confidence on an
    exact time of these lower CIGs is a bit low at this time, it
    appears that the best timing of IFR or lower CIGS may hold off
    until this evening. Thereafter, CIGs are likely to lower into the
    into the LIFR tonight and for Sunday. Also expect low
    visibilities in fog and drizzle to become an increasing issue,
    particularly late tonight and on Sunday as a surface warm front
    approaches the area from the south.
