...Locally dense patchy freezing fog into tonight...

Patchy fog continues to develop this evening and is expected to
continue into tonight. The fog formation is not expected to be
widespread but could be locally dense with visibility dropping
below a quarter of a mile. Freezing fog is also a concern tonight
as temperatures continue to drop which could lead to a light
glazing of ice on surfaces along with reduced visibility. Elevated
surfaces are of particular concern into tonight for a light glazing
of ice. Use caution when traveling and be prepared for changes in
visibility.
