MADISON, Wis. (WMTV) – After a rainy day, much of that precipitation is expected to move out by early evening. Accumulations here at Dane County were less than 1/4″. As the rain moves out, fog will be on its way back in. The National Weather Service has placed all of our areas under a Dense Fog Advisory until 10 am Saturday. At times we can expect the fog to bring down the visibility to near zero in some areas, so just be cautious on the roads as your visibility may drop very quickly.
