Daffodils under snow, St. Louis, Missouri, USA, 24 March 2013 (AP)
The snowstorm stretched from the American Rockies to the Mid-Atlantic states dumping as much as 30 cm or more in Colorado, Kansas and Missouri with almost 50 cm in parts of Illinois.
The spring snow is not unusual but such heavy amounts in late March have broken records in many cities according to the U.S. National Weather Service.
Although only reporting about 3 cm, Washington, DC, had its snowiest March day since 2011.
The storm gave New York City a rain/snow mix before moving out to sea.
