An arctic blast sweeping into New England on Friday into Saturday brought biting winds and record low temperatures falling below zero.
The high-powered winds impact was felt across Massachusetts, from knocked down trees to power outages.
The extreme conditions also created seldom seen phenomena.
Sea smoke, which is formed when cold air sits over warmer waters, blanketed areas including the Boston Harbor and a seawall in Marshfield. Mount Washington, in New Hampshire — the highest peak in northeastern US — also became colder than an average week on Mars, according to The Washington Post, with a windchill of 108 degrees below zero.
