When saturated air is cooled, it cannot take up more water vapor. This is because it has already reached its maximum capacity for holding water vapor at that particular temperature and pressure. This is known as the air's dew point, and any further cooling will cause excess water vapor to condense into visible droplets, such as fog or precipitation (like snow). The relative humidity will change as a result of the change in temperature, and fog or precipitation may form, but the air cannot take up more water vapor.
