Mainly clear skies over eastern Wisconsin will allow for the formation of fog again tonight. The fog will gradually thicken during the evening. Although the visibility at most locations is expected to edge downward to between 1 and 2 miles by 1100 PM...the fog will become much more dense in some areas. Visibilities as low as 1/4 mile could develop in low-lying areas and river valleys. Anyone traveling this evening should be prepared for the possibility of encountering sudden changes in visibility. If you encounter a fog bank while driving on the Highway...always use your low-beam headlights and slow down to a speed at which you can safely stop if you encounter an animal or object in the roadway.
