MADISON, Wis. (WMTV) – Again, we’re looking at another foggy day with mild temperatures for Southern Wisconsin. Visibilities around the area have been up and down all day, dropping to below 1/8 mile in some areas at times. Dense Fog Advisories continue for the southern counties until 6 pm this evening. I am expecting these advisories to be extended and shifted to other counties. Our setup with the fog is very fluid and at times visibility may improve but then come back down.
