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.

Meteorological history
Шаблон:Storm path The nor'easter originated as a weak frontal system over Alabama late on December 4.[4] Several hours later, the system began to grow more organized, transitioning into an extratropical cyclone over North Carolina by 03:00 UTC on December 5.[5] The developing low-pressure exited the coast 6 hours later, with a minimum central pressure of Шаблон:Convert.[6] After this point, the nor'easter began to undergo bombogenesis, reaching an initial central pressure of Шаблон:Convert off the coast of Rhode Island at 18:00 UTC that day.[7] After making landfall in Nantucket 3 hours later with a central pressure of Шаблон:Convert,[8] the low-pressure strengthened further, reaching its peak intensity of Шаблон:Convert at 06:00 UTC on December 6 off the coast of Maine.[9] After slowly weakening for several hours that, it made landfall in New Brunswick at 18:00 UTC with a central pressure of Шаблон:Convert.[10] The system weakened slightly over New Brunswick, but began to weaken faster after emerging into the Gulf of Saint Lawrence.[11] At 21:00 UTC on December 7, the weakening nor'easter made landfall in Newfoundland with a central pressure of Шаблон:Convert.[12] After this point, the low-pressure began to rapidly weaken, with the system dissipating inland over Newfoundland the next day.[13]
Preparations and impact
Winter Storm Warnings were issued on December 4 and 5 in advance of heavy, wet snow and possible blizzard conditions across New England, including both Boston and Portland. Winter Weather Advisories were issued further south, and High Wind Warnings were placed into effect on Cape Cod in anticipation of hurricane-force wind gusts.
Southern New England
In Connecticut, near-whiteout conditions were reported for prolonged periods on December 5, leading to numerous crashes on interstates. I-84 was closed in both directions from Tolland, Connecticut, to the Massachusetts state line for hours as a result of numerous crashes and a lack of snowplows.[3]
Massachusetts State Police lowered the speed limit to 40 mph on I-90 at noon on December 5 due to ongoing whiteout conditions on the roadways. A crash was reported on I-90 in Millbury a few hours later, prompting the closure of two lanes. Over 1,800 snow removal vehicles were deployed in Massachusetts to clear roads of snow and ice. Over 26,000 power outages resulted in Massachusetts, and several thousand of those were not restored until the next day.

Northern New England
In New Hampshire, Mount Washington recorded the second-highest snow total during the storm with Шаблон:Convert falling there and the highest wind gust during the storm, with a peak wind gust of Шаблон:Convert.

Carrabassett Valley, Maine, recorded the highest snowfall total during the storm, with a total of Шаблон:Convert.
