Patchy Dense Fog and Pockets of Freezing Drizzle Overnight... With a moist air mass in place, areas of fog and drizzle have been developing across the southern Adirondacks, Lake George Saratoga Region, southern Vermont and the Berkshires. Some of the fog may be locally thick with visibility under one mile at times. If you will be traveling overnight, be prepared for reduced visibility at times. In addition, temperatures across the higher elevations of the Adirondacks, Greens and Berkshires are close to or just below the freezing mark. Any fog or drizzle could be allowing for a thin layer of ice to develop on any untreated surfaces, so keep in mind that some slippery conditions are possible through the overnight hours as well.
