AVIATION [Beginning 19Z Tuesday]...
Mainly VFR conditions are expected this afternoon. However, as
low-level moisture increases with the approach of the cold front,
CIGS should gradually lower overnight, with some IFR or even LIFR
possible. Some fog is possible, especially in the evening and in the
southeast parts of the area. Forecast soundings show a deep
saturated layer up to about 7000 ft tomorrow, so low CIGS should
linger into the daytime hours, with some -DZ or -SHRA possible.
