As low clouds begin to clear late this evening and through the overnight, conditions for fog development will become more favorable, especially across eastern Indiana and western Ohio. Some dense fog is possible and may result in visibility of one quarter mile or less. Locations farther east into Ohio and farther south into northern Kentucky could see visibility worsen through daybreak. Motorists should be prepared for rapid changes in visibility. Allow for greater distances between vehicles, use low beam headlights, and allow extra time to reach your destination.
