Special Weather Statement

... Patchy dense fog tonight into early Sunday morning...

A moist southerly flow of air combined with nighttime cooling has
resulted in areas of fog across much of the eastern half of Upper
Michigan tonight. This fog has become locally dense... restricting
visibility to one quarter mile or less in some places. The
thickest fog is more prevalent in low lying areas... especially
near bodies of water or wetlands. Expect this patchy dense fog to
linger through sunrise before burning off by mid Sunday morning.

If you must drive tonight... be prepared for patches of dense fog
with near zero visibility. Slow down and leave plenty of distance
between you and the vehicle ahead of you. Use your low beam
headlights.
