dense in spots, with visibilities of 1/4 mile or less, especially
along the southern Bay and near the city of Green Bay.
If you have travel plans this morning, be on alert for rapidly
changing or poor visibilities as low as 1/4 mile or less in spots.
Plan on extra time to reach your destination, and allow extra
room between you and the car in front of you.
Visibilities should begin to improve from west to east over the
next couple of hours as a cold front moves across the area.
