PATCHY DENSE FOG THIS MORNING... Patchy dense fog, with visibilities of one quarter mile or less, will continue across parts of central Wisconsin and the Fox Valley this morning. The dense fog is expected to continue lift the next hour or two. Motorists traveling across the region this morning can expect rapidly changing and poor visibilities at times. Remember to turn on your low-beam headlights and allow extra distance between you and the car in front of you.
