Jacksonville residents woke up to a Christmas morning draped in a blanket of slightly fogged air, as reported on the National Weather Service’s website. The morning fog, expected to lift before 7 am, gave way to mostly cloudy skies with the temperature hovering near 52 degrees Fahrenheit. The festive quiet of the city was matched with a gentle breeze from the north at a pace of 7 miles per hour, reassuring in its consistency.
