The North American blizzard of 2006 was a nor'easter that began on the evening of February 11, 2006. It dumped heavy snow across the Mid-Atlantic and New England states, from Virginia to Maine through the early evening of February 12, and ended in Atlantic Canada on February 13. The major cities from Baltimore to Boston received at least a foot of snow, with a second-highest amount of 26.9 inches (68 cm) in New York City, the most since at least 1869, the start of record keeping, only broken by the January 2016 United States blizzard nearly 10 years later.
The February 9–10, 2010 North American blizzard was a winter and severe weather event that afflicted the Midwest, Mid-Atlantic and New England regions of the United States between February 9–11, 2010, affecting some of the same regions that had experienced a historic Nor'easter three days prior. The storm brought 10 to 20 inches of snow across a wide swath from Washington, DC to New York City, with parts of the Baltimore metro area receiving more than 20 inches (51 cm). This storm began as a classic "Alberta clipper", starting out in Canada and then moving southeast, and finally curving northeast while rapidly intensifying off the New Jersey coast, forming an eye. The National Weather Service, in an interview with The Baltimore Sun's weather reporter Frank Roylance, likened this storm to a Category 1 hurricane. Forecasters told Roylance that "Winds topped 58 mph over part of the Chesapeake Bay, and 40 mph gusts were common across the region as the storm's center deepened and drifted slowly along the mid-Atlantic coast". This storm system, in conjunction with the first storm 3 days prior, has been nicknamed Snoverkill.
The February 25–27, 2010 North American blizzard was a winter storm and severe weather event that occurred in the Mid-Atlantic and New England regions of the United States between February 24 and 26, 2010. The storm dropped its heaviest snow of 12 to 24 inches across a wide area of interior New England, New York, and Pennsylvania. The storm also brought flooding rains to coastal sections of New England, with some areas experiencing as much as 4 inches (10 cm). Aside from precipitation, the Nor'easter brought hurricane-force sustained winds to coastal New England.
The December 2010 North American blizzard was a major nor'easter and historic blizzard affecting the Contiguous United States and portions of Canada from December 22–29, 2010. From January 4–15, the system was known as Windstorm Benjamin in Europe. It was the first significant winter storm of the 2010–11 North American winter storm season and the fifth North American blizzard of 2010. The storm system affected the northeast megalopolis, which includes major cities such as Norfolk, Philadelphia, Newark, New York City, Hartford, Providence, and Boston. It brought between 12 and 32 inches of snow in many of these areas.
The 2011 Halloween nor'easter, sometimes referred to as "Snowtober," "Shocktober," "Storm Alfred," and "Oktoberblast," was a large low pressure area that produced unusually early snowfall across the northeastern United States and the Canadian Maritimes. It formed early on October 29 along a cold front to the southeast of the Carolinas. As it moved up the East Coast, its associated snowfall broke records in at least 20 cities for total accumulations, resulting in a rare "white Halloween" two days later.
The February 2013 North American blizzard, also known as Winter Storm Nemo and the Blizzard of 2013, was a powerful blizzard that developed from the combination of two areas of low pressure, primarily affecting the Northeastern United States and parts of Canada, causing heavy snowfall and hurricane-force winds. The storm crossed the Atlantic Ocean, affecting Ireland and the United Kingdom. The nor'easter's effects in the United States received a Category 3 rank on the Northeast Snowfall Impact Scale, classifying it as a "Major" Winter Storm.
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 2012–13 North American winter started out somewhat early, as the remnants of Hurricane Sandy brought heavy snow to the mountains of West Virginia in late October. Later, a strong nor'easter affected the weary Northeastern United States, hampering storm recovery efforts and dropping several inches of snow. The rest of the winter featured several other notable events, such as a Christmas winter storm that affected most of the Eastern United States, and the most notable event occurring in early February, when a powerful blizzard struck the Northeast and brought record snow to some areas. During the winter, a weak El Nino was expected to influence weather conditions across the continent.
The March 2017 North American blizzard was a major late-season blizzard that affected the Northeastern United States, New England and Canada, dumping up to 3 feet of snow in the hardest hit areas, mainly New York, Vermont, New Hampshire and Southern Quebec. Forming out of an extratropical cyclone near the Northwest, the storm system dived into the northern portions of the United States, dropping light to moderate snow across the Great Lakes, Upper Midwest on March 11–12 before reaching the Ohio Valley the next day. It later coalesced into a powerful nor'easter off the East Coast, producing a swath of heavy snowfall across a large portion of the Northeast. The storm was given various unofficial names, such as Winter Storm Stella, Blizzard Eugene, and Blizzard of 2017.
The 2017–18 North American winter saw weather patterns across North America that were very active, erratic, and protracted, especially near the end of the season, resulting in widespread snow and cold across the continent during the winter. Significant events included rare snowfall in the South, an outbreak of frigid temperatures that affected the United States during the final week of 2017 and early weeks of January, and a series of strong nor'easters that affected the Northeastern United States during the month of March. In addition, flooding also took place during the month of February in the Central United States. Finally the winter came to a conclusion with a powerful storm system that caused a tornado outbreak and blizzard in mid-April. The most intense event, however, was an extremely powerful cyclonic blizzard that impacted the Northeastern United States in the first week of 2018. Similar to the previous winter, a La Niña was expected to influence the winter weather across North America.
The March 1–3, 2018 nor'easter caused major impacts as well as significant coastal flooding in the Northeastern, Mid-Atlantic and Southeastern United States. It originated as the northernmost low of a stationary front over the Midwest on March 1, which moved eastward into the Northeast later that night. A new low pressure system rapidly formed off the coast on March 2 as it slowly meandered near the coastline. It peaked later that day and brought hurricane-force winds to coastal New England before gradually moving out to sea by March 3. Producing over 2 feet (24 in) of snow in some areas, it was one of the most significant March snowstorms in many areas, particularly in Upstate New York. In other areas, it challenged storm surge records set by other significant storms, such as Hurricane Sandy. It was unofficially named Winter Storm Riley by The Weather Channel.
The 2020–21 North American winter was the most significant winter season to affect North America in several years, and the costliest on record, with a damage total of at least $33.35 billion. The season featured 6 storms ranking on the Regional Snowfall Index scale, with 4 storms ranking as at least a Category 3. Most of the winter's damage and fatalities occurred due to a historic and major cold wave in mid-February. Several other significant events occurred, including a crippling early-season ice storm in the Southern Plains, a powerful nor'easter in mid-December, another major nor'easter in early February, two major and widespread winter storms in mid-February, and a major blizzard in the Rocky Mountains in mid-March. The winter-related events were responsible for at least 358 fatalities, making it the deadliest season since 1992–93. A La Niña pattern influenced much of the winter in North America.
The December 5–6, 2020 nor'easter brought heavy snowfall, hurricane-force wind gusts, blizzard conditions, and coastal flooding to much of New England in the first few days of December 2020. The system originated on the Mid-Atlantic coast late on December 4. It then moved up the East Coast of the United States from December 5–6, bombing out and bringing heavy wet snow to the New England states. It brought up to 18 inches (46 cm) of snow in northern New England, with widespread totals of 6–12 inches (15–30 cm) farther south.
The December 15–17, 2020 nor'easter was a powerful nor'easter that hammered the Northeastern United States and produced widespread swaths of over 1 foot (12 in) of snow in much of the region from December 15–17, 2020, ending a 1,000+ day high-impact snowstorm drought in much of the Mid-Atlantic and coastal New England regions. The system developed out of a weak area of low-pressure that first developed over the Central United States producing some snowfall before moving eastward, and by December 16, a new, dominant area of low pressure began to develop along the Southeast coast. This low steadily deepened as it moved along and impacted the Mid-Atlantic coastline, prompting several winter-related advisories and warnings for much of the Northeast.
The January 31 – February 3, 2021 nor'easter, also known as the 2021 Groundhog Day nor'easter, was a powerful, severe, and erratic nor'easter that impacted much of the Northeastern United States and Eastern Canada from February 1–3 with heavy snowfall, blizzard conditions, strong gusty winds, storm surge, and coastal flooding. The storm first developed as an extratropical cyclone off the West Coast of the United States on January 25, with the storm sending a powerful atmospheric river into West Coast states such as California, where very heavy rainfall, snowfall, and strong wind gusts were recorded, causing several hundred thousand power outages and numerous mudslides. The system moved ashore several days later, moving into the Midwest and dropping several inches of snow across the region. On February 1, the system developed into a nor'easter off the coast of the Northeastern U.S., bringing prolific amounts of snowfall to the region. Large metropolitan areas such as Boston and New York City saw as much as 18–24 inches (46–61 cm) of snow accumulations from January 31 to February 2, making it the worst snowstorm to affect the megalopolis since the January 2016 blizzard. It was given the unofficial name Winter Storm Orlena by The Weather Channel.
The February 6–8, 2021 nor'easter, also referred to as the 2021 Super Bowl Sunday nor'easter, was a strong and fast-moving nor'easter that started out in the Southern United States, before impacting the Mid-Atlantic and New England states on Super Bowl Sunday, in February 2021. The storm struck the region just days after another significant nor'easter impacted the same general regions. Developing on February 6 along a stationary front in the Southern United States and moving northeastward, the imminent impacts from the nor'easter forced several vaccination sites in the Northeast to temporarily close again for the following days. The storm caused one indirect death, and damage estimates are currently undetermined. It was unofficially named Winter Storm Quade by The Weather Channel.
The April 2021 nor'easter, also referred to as the 2021 Spring nor'easter, was a significant late-season nor'easter that impacted much of New England with heavy snowfall, gusty winds, thundersnow, and near-whiteout conditions from April 15–17, 2021. The system originated from a weak frontal system late on April 14 over North Carolina, which moved into the ocean the next day and began to strengthen. The low-pressure steadily deepened as it moved up the East Coast, and developed an eye-like feature just prior to peak intensity. It prompted a fairly large area of Winter Storm Warnings across interior sections of New England, with Winter Weather Advisories being issued closer to the coast. Over 20,000 customers lost power at the height of the storm on April 16 due to heavy wet snow, and near-whiteout conditions were reported in many areas. Several injuries, some serious, occurred as well, mostly due to traffic incidents on poorly-treated roadways during the storm. Damage estimates from the system are currently not calculated.
The January 2022 North American blizzard caused widespread and disruptive impacts to the Atlantic coast of North America from Delaware to Nova Scotia with as much as 2.5 feet (30 in) of snowfall, blizzard conditions and coastal flooding at the end of January 2022. Forming from the energy of a strong mid- to upper-level trough, the system developed into a low-pressure area off the Southeast United States on January 28. The system then quickly intensified that night as it traveled northeast parallel to the coast on January 29, bringing heavy snowfall blown by high winds to the East Coast of the continent. Further north, it also moved inland in Maine and its width meant it strongly impacted all three of Canada's Maritime provinces. In some areas, mainly the coastal regions of New Jersey, Long Island and Massachusetts, it was the first blizzard since a storm in January 2018. The storm was considered a "bomb cyclone" as it rapidly intensified and barometric pressure dropped at least 24 millibars over a 24-hour period. The storm was given names such as Blizzard of 2022 and Winter Storm Kenan.
The 2022–23 North American winter was an unusually warm winter for the east and an unusually cold winter for the west in North America, as it occurred across the continent from late 2022 to early 2023. The winter season in North America began at the winter solstice, which occurred on December 21, 2022, and it ended at the March equinox, which occurred on March 20, 2023. The first day of meteorological winter began on December 1 and unofficially ended on February 28; winter storms may still occur outside of these limits.
