January 2015 North American blizzard

The January 2015 North American blizzard was a powerful and severe blizzard that dumped up to 3 ft 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. 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 ft. 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.

Meteorological history
On January 23, a low-pressure area developed off the Pacific Northwest, before moving over the Canadian Prairies by January 24. The storm system quickly moved southeastward into the Upper Midwest during the evening of January 24, taking a path typical of an Alberta clipper. As it progressed southward, the storm intensified, with frontogenesis occurring the next day. By noon on January 25, the upper-level low was centered near the border between Iowa and Missouri in correlation with a weak shortwave trough. Moisture from the Gulf of Mexico wrapped around the system from the south, resulting in widespread rainfall and snow over the Midwest. Throughout the day, the system traversed eastward along the Kentucky-Tennessee border. Snowfall remained concentrated along a cold front north of the Ohio River. At 09:00 UTC on January 26, the Weather Prediction Center began issuing storm summaries on the developing disturbance while the low-pressure system was centered near Bluefield, West Virginia. At the time, mixed precipitation was occurring over northern Appalachia. As this system tracked eastward, it gradually weakened; however, at the same time, a new low-pressure system formed off the coast of North Carolina and began to track north-northeastward, eventually becoming the dominant low of the storm. Early on January 30, the nor'easter left the East Coast, even as another winter storm began to impact the region. During the next day, the former nor'easter continued to accelerate eastward across the North Atlantic, even as it rapidly weakened. On January 31, the winter storm was absorbed by a much more powerful extratropical cyclone developing over Western Europe.

Forecasting controversy
After the storm had passed, a number of New York City residents criticized New York Governor Andrew Cuomo's decision to shut down the city's subway system; it had never previously been closed due to snow. The nor'easter dropped much less snow in the city than originally expected, totaling 9.8 in in Central Park. The models were 50 miles off; the storm failed to bring moisture back to New York City and New Jersey.

Preparations
On January 25, 2015, blizzard warnings were issued for areas of coastal New England, New York and New Jersey. High winds and heavy snow were forecast for the evening of January 26 and all day January 27, impacting a 250-mile area from New York City to Boston. On January 26, many roads in New York and New England were closed to all vehicles except emergency vehicles due to life-threatening conditions on area roadways.

Many churches and other houses of prayer remained open to those in need of a warming center.

At the height of the storm, a 300-mile (480 km) stretch of Interstate 95 from northern New Jersey to the Massachusetts/New Hampshire border was closed in conjunction with travel bans in the impacted areas. Portions of Interstates 78, 80, 84, 87, 90, 91 and 93 were also shut down by the storm.

Pennsylvania
In preparation for the winter storm, the Pennsylvania Department of Transportation deployed approximately 350 salting trucks to treat major roadways. On January 26, Pennsylvania Governor Tom Wolf signed a disaster emergency proclamation in an attempt to distribute state resources as quickly as possible. Philadelphia Mayor Michael Nutter closed municipal offices and schools for January 27 and cancelled trash collection for the day. Meanwhile, SEPTA's bus lines closed while its train system ran 24 hours a day for Monday and Tuesday. According to the Philadelphia Office of Emergency Management, the snow emergency declaration was lifted at 6:00 a.m. Tuesday morning.

New Jersey
The South Brunswick Police Department said in a press release on January 25 that additional officers and public works staff would be on duty throughout the storm. The department urged residents to make preparations in anticipation that travel would be impossible for several days. The Monroe Township Office of Emergency Management released a guideline to ensure residents were safe and prepared for the nor'easter. New Jersey Governor Chris Christie declared a state of emergency for the duration of the storm; in a morning press conference, Christie also urged all nonessential personnel to remain off roadways. A travel ban was issued later that day, to be put in effect on January 26 at 11pm; Amtrak and New Jersey Transit services were also suspended.

New York
In a statement on January 25, New York Governor Andrew Cuomo urged residents to take their necessary safety precautions and prepare for the possibility of disrupted commute on Monday and Tuesday.

The State Emergency Operations Center in Albany was expected to be staffed beginning early on January 26 to coordinate with all affected counties. At least 1,806 plows and 126,000 tons of salt were expected to be divided across the region, and the National Guard was expected to deploy more than six dozen personnel and 20 vehicles throughout the region. New York State Police were expected to bring in additional personnel, as well as supply at least 50 4x4 vehicles, 8 all-terrain vehicles, and 8 snowmobiles.

At its major transportation facilities, the Port Authority of New York and New Jersey readied more than 200 piece of snow equipment at its airports, more than 60 pieces of snow equipment for its bridges and tunnels, hundreds of thousands of gallons of liquid anti-icer chemicals and thousands of tons of solid de-icers, plow-equipped trains, liquid snow-melting agent trains, and a "jet engine" plow. The New York State Thruway Authority activated its emergency operations ahead of the winter storm and was expected to supply 338 snowplows, 18 snowblowers, 55 front-end loaders, and approximately 126,000 tons of salt. The New York State Department of Transportation also activated its emergency operations, mobilizing 162 snow plows and nearly 338 operators to Long Island and the Hudson Valley, totaling to approximately 600 plows and 1,300 operators and supervisors across downstate New York. A total of 1,444 snow plows and 3,629 operators and supervisors would be available statewide.

New York City Mayor Bill de Blasio warned of 2 to 3 ft of snow, and said, "Prepare for something worse than we have seen before." De Blasio ordered all vehicles off the streets by 11pm on January 26, and declared that, with the exception of emergency and government vehicles, anyone driving in New York City after 11pm on January 26 would be fined.
