Periods of MVFR/IFR ceilings are possible along the coast later this evening and overnight, but offshore flow could limit its duration and extent. All other area should remain VFR throughout the next 24 hours, although some pockets of MVFR/IFR in fog or low stratus are possible in sheltered valleys.
