Fog, dense in several valley locations, will be most prevalent in locations south of the Mountain Parkway. Visibilities will be reduced to below a quarter of a mile at times and visibilities will vary significantly over short distances. The fog should gradually lift and dissipate by the 9 to 10 AM EDT timeframe. If traveling this morning, slow down, use low beam headlights when you encounter any fog, and allow extra time to reach your destination.
