Widespread dense fog reducing visibilities to less than a quarter mile can be expected through about mid-morning. The combination of the fog and surface temperatures near or below freezing may also create slippery roads...especially on bridges and overpasses. Anyone traveling this morning should be prepared to encounter fog...and plan accordingly. If you encounter a fog bank while driving on the Highway...always use your low-beam headlights and slow down to a speed at which you can safely stop if you encounter an animal or object in the roadway. Slow down and travel with care until visibilities improve later this morning.
