AREAS OF FOG TO REDUCE VISIBILITY THROUGH THE MORNING COMMUTE... Areas of fog with visibilities between one half and two miles continue early this morning across central and eastern Massachusetts and into Rhode Island. Visibilities should remain at those levels through the morning commute, which may hamper travel for commuters. Improvement is anticipated by mid-morning. Motorists should be prepared for sudden changes in visibility. Use low beam headlights and keep a safe distance between your vehicle and the one ahead of you.
