Fog will be locally dense in pockets over southern Wisconsin from now through the mid morning. Visibility may be suddenly reduced to 1/4 mile or less in these dense pockets. Caution is advised for the morning commute.
At this time the need for a Dense Fog Advisory will be monitored using surface observation trends, as mid to high level cloud cover is spreading in from the west. This cloud cover may allow for some mild improvements in visibility if it holds together.
