Early February cold wave

Following an arctic front moving in the night of February 2,[71] extremely cold temperatures settled into the Northeast on February 3 and 4. Schools in Boston, Massachusetts closed on February 3 in anticipation of the cold temperatures.[72] On February 4, 2023, Boston experienced a temperature of −10 °F (−23 °C), the first double-digit negative temperature in the city since the 1950s.[73] Nantucket, Massachusetts was −3 °F (−19 °C), which tied a record low also set in both 2004 and 1962.[74] Portland, Maine had a record low wind chill of −45 °F (−43 °C).[75] Atop Mount Washington in New Hampshire, the wind chill hit −108 °F (−78 °C), the coldest wind chill in the United States, with an air temperature of −47 °F (−44 °C) combined with wind speeds of 97 mph (156 km/h).[76][77] The cold wave caused 5,000 power outages in Connecticut. The temperature in Bridgeport, Connecticut of −4 °F (−20 °C) broke the previous record by 9 °F (5 °C).[78] Temperatures in Burlington, Vermont were −15 °F (−26 °C) on February 4, leading to steam devils on Lake Champlain.[79] Several frostquakes occurred in Maine.[80] An all-time record low temperature was set atop Whiteface Mountain, at −40.2 °F (−40.1 °C).[81] Strong winds relating to the arctic front killed a passenger in a car in western Massachusetts when a tree fell on the car.[82] 60,000 customers lost power due to the cold wave in New England, with 46,000 in Massachusetts alone.[83] 191 flights were delayed and 62 flights were cancelled out of Logan International Airport due to the bitter cold.[84]

Kennedy International Airport’s low of 4 °F (−16 °C) were low enough to set daily records.[87] Newark, New Jersey also recorded a record low of 5 °F (−15 °C), although it was the only site in the state to break a daily record. Temperatures in the state got as low as −10 °F (−23 °C) at High Point Monument in Sussex County, New Jersey.[88]

The National Centers for Environmental Information documented that this winter storm and cold wave caused $1.6 billion (2023 USD) in damage.[89]

A major blizzard struck the Great Plains in early April 2023. In preparation for the storm, blizzard warnings were issued for over 800 mi (1,300 km), from Wyoming to Minnesota.[118] The snowstorm in Casper, Wyoming resulted in them setting both a one-day and two day record for snowfall, at 26.7 in (68 cm) and 37.4 in (95 cm). Atlantic City, Wyoming recorded 48.8 in (124 cm).[119] Kenora, Ontario recorded 27.2 cm (10.7 in) of snow.[120] As a result of the storm, parts of Interstate 29, Interstate 90 and Interstate 94 was closed due to the storm, and both Fargo and Grand Forks, North Dakota had record deep snowpack for so late in the spring.[121] Two people were killed in the winter storm due to a car crash on icy roads in Ward County, North Dakota.[122] Blowing snow in southern Manitoba resulted in several highways shutting down as well.[123] Mount Rushmore and Badlands National Park closed due to the snow.[124] In addition, Salt Lake City set a record cold high after the storm, at only 33 °F (1 °C).[125] As a result of the snow, as well as forecasted high temperatures of 34 °F (1 °C), the Minnesota Twins postponed their home opener by a day.[126] Further east, a severe ice storm struck Quebec, resulting in a fatality in Montreal and over a million customers losing power.[127] In addition to winter weather impacts, the system also spawned a severe weather and tornado outbreak that affected the Midwestern United States, Mississippi Valley, and Great Lakes. A total of 27 tornadoes were confirmed along with five fatalities.[128]

Early May winter storm

A record breaking winter storm affected the Upper Peninsula of Michigan from May 1 to 2. The city of Marquette, Michigan received 26.2 in (67 cm) of snow, which made the city record their snowiest May on record. 19.8 in (50 cm) of that total fell on May 1, which became the snowiest day in May for the city.[129] Over ten thousand customers in the Upper Peninsula lost power.[130] Further south, Green Bay, Wisconsin recorded 2.2 in (5.6 cm) of snow.[131] West Virginia set a monthly snowfall record with Davis receiving 20.3 in (52 cm) of snow.[132] Further north, Pittsburgh had a record cold high on May 2 due to the system, at 44 °F (7 °C).[133]

Records

Eastern United States

Due to unfavorable storm tracks,[134] the Eastern United States received little snowfall. For the first time in history, Charlotte, North Carolina did not even record a trace of snow.[135] New York City also recorded its least snowy winter with just 2.3 in (5.8 cm) of snow, as well as their second warmest winter and warmest January on record.[136] The record warm January contributed to the first snowfall occurring on February 1, the latest first date for snowfall on record.[137] The season also became the least snowy on record at Baltimore, Atlantic City, Bridgeport, Oswego and Elkins, as well as tying for the second least snowy at Philadelphia, becoming the third least snowy in Washington DC and fourth least snowy in Boston.[138][139][140] In addition to the lack of snow, it was also one of the warmest winters on record, with Massachusetts tying for their warmest winter at an average temperature of 33.7 °F (0.9 °C), with Tupelo, Mississippi also recording their warmest winter.[141][142] Pittsburgh recorded their least snowy February at only 0.2 in (0.51 cm) of snow, with seasonal snowfall being well below normal.[143] Despite that, Buffalo, New York recorded its fifth snowiest winter on record with 132.8 in (337 cm) of snow falling, mainly due to lake effect snowstorms in November and December 2022.[144] In addition, Mount Washington recorded their snowiest June on record.[145]

Midwestern United States

Western United States

The same pattern that contributed to little snow in the east helped give major snow to the Western US. The city of Flagstaff, Arizona recorded their third snowiest January on record.[150] The winter also became the second snowiest at the UC Berkeley Central Sierra Snow Lab,[151] which also made it the second deepest snowpack in California history.[152] This also helped produce copious amounts of rain in areas too warm for snow, with Hanford, California recording their wettest day on record on February 24,[153] and San Francisco recorded their third wettest winter on record.[154] In addition, the first quarter of 2023 became the coldest on record for Lander, Wyoming.[149] Near-record snow at the North Rim of the Grand Canyon National Park resulted in the opening date being delayed to June 2.[155]
