The January 2015 North American blizzard was a powerful and severe blizzard that dumped up to 3 feet (910 mm) of snowfall in parts of New England. Originating from a disturbance just off the coast of the Northwestern United States on January 23, it initially produced a light swath of snow as it traveled southeastwards into the Midwest as an Alberta clipper on January 24–25. It gradually weakened as it moved eastwards towards the Atlantic Ocean, however, a new dominant low formed off the East Coast of the United States late on January 26, and rapidly deepened as it moved northeastwards towards southeastern New England, producing pronounced blizzard conditions. The nor’easter then gradually weakened as it moved away into Canada. The storm was also given unofficial names, such as Blizzard of 2015, and Winter Storm Juno.

The nor'easter disrupted transportation, with snow emergencies declared in six states and travel bans enacted in four of these states – Connecticut, New Jersey, Massachusetts, and Rhode Island – as well as in New York City. Most passenger rail service was suspended, and thousands of flights were cancelled.[3][4] Schools and activities saw weather-related cancellations for one or more days.

Before the blizzard struck, meteorologists had been anticipating that the impending storm would be "historic" and "record-breaking", with predictions of snowfall accumulations in major metropolitan areas such as New York City of up to 2–3 feet (24–36 in). However, snowfall fell significantly short of what was anticipated, mainly due to a shift of the storm's track. In the aftermath of the storm, citizens criticized the local government for shutting down the subway system in New York City for the storm.
