Update: Dense Fog Advisory Chicago area-wide discontinued

Update 3:30AM CST…

Winds have picked up, gusting at times in excess of 20 miles per hour, subsequently mixing the air at ground level just enough to significantly improve visibilities area-wide. As a result,  the  Dense Fog Advisory for the Chicago area has been discontinued.

_______________________________________________________________________________________________________

A Dense Fog Advisory (grey-shaded area on the headlined map) calling for visibilities lowering to a quarter-mile or less will be in effect tonight into Sunday forenoon for all of the Chicago area. Visibility could drop to near zero later tonight and early Sunday in some spots, so those traveling should be alert to rapidly changing visibility and hazardous driving conditions.
