...VISIBILITIES IMPROVING ACROSS MOST OF THE AREA...BUT PATCHY
DENSE FOG MAY PERSIST IN LOW-LYING AREAS FOR ANOTHER HOUR OR
TWO...

The widespread dense fog that developed over portions of
central and north-central Wisconsin had begun to lift, and a
steady improvement in the conditions across most of the area is
expected during the next hour or two. However, patches of dense
fog with visibilities down as low as a few hundred feet will
probably linger a bit longer in low-lying areas and near lakes,
streams, and rivers.

Motorists should remain alert for sudden variations in the
visibility due to lingering patches of dense fog. Be sure to use
low-beam headlights until the fog is completely gone. Be sure to drive
at a speed that will allow you to safely stop if you unexpectedly
encounter an object or animal on the road.
