Based on the astronomical definition, winter began on the winter solstice on December 21, 2021 and ended on the spring equinox on March 20, 2022.[1] Based on the meteorological definition, the first day of winter started on December 1 and the last day was February 28.[2] These dates historically describe the period in each year when winter storms are most likely to occur. However, winter storms may occur outside of these limits, as shown by the early formation of this season's mid-October winter storm on October 12. Since both definitions of winter span the start of the calendar year, it is possible to have a winter storm spanning two different years. In addition, major winter events can occur well after the official start of spring, as close as June in some cases, as shown by a very late-season winter storm that impacted Colorado in late May 2022 with heavy snow following warm temperatures just a day beforehand.
Seasonal forecasts
Temperature outlook
Precipitation outlook
On October 13, 2021, The Weather Channel (TWC) released its U.S. winter temperature outlooks for the 2021–22 winter season.[3] The forecasts reflected the likelihood of a weak La Niña pattern and weak polar vortex during much of the season. Overall for the winter, significantly above-average temperatures were forecast for most of the Southern Tier, with near-average temperatures in the Central and much of the Northeastern United States. Slightly below-average temperatures were expected in most of the north-central and northwestern U.S. During the first half of the season, a relatively weak La Niña was expected to result in widespread below-average temperatures across the northern half of the country, with widespread above-average temperatures in the southern half. However, as both the La Niña and polar vortex were expected to strengthen later in the season, widespread above-average temperatures were forecast in most of the U.S. during the latter half of the winter, especially in the South and East. Below-average temperatures were still expected to continue in the far Northwestern U.S.[3]
On October 21, 2021, the National Oceanic and Atmospheric Administration's Climate Prediction Center released its U.S. Winter Outlook for the upcoming winter.[4] The temperature and precipitation outlooks reflected a typical La Niña weather pattern during the winter. Significantly above-average temperatures were forecasted across the Southern Tier, especially in the Southeast, with slightly above-average temperatures forecast in the Ohio Valley and Northeast. Near to below-average temperatures were expected in the far northwestern U.S. Below-average precipitation was expected across the far Southern Tier, with particularly in the Southwest, with above-average precipitation forecast in the far Northwestwern U.S., as well as the Ohio Valley and surrounding regions. Near-average precipitation was expected in the Central U.S., Northern Plains, and Northeast. Drought was forecasted to improve and end in the Pacific Northwest, while it was expected to develop or worsen across the Southwest. Drought was not expected in the eastern half of the country.[4]
Seasonal summary
The 2021–22 winter season began with the formation of a significant winter storm in the Western United States on October 12, resulting in heavy snow accumulations of up to 28 in (71 cm) across much of the Intermountain West and over 80 rescues due to blizzard-like conditions in Utah.[5][6] The system was estimated to have caused at least $50 million in damages.[7] After a one-month break in winter weather events due to unfavorable conditions for winter storms, a blizzard began to develop across south-central Canada and the Upper Midwest on November 11.[8] December 2021 saw a record warm month across the Lower 48. Ten states (New Mexico, Texas, Louisiana, Mississippi, Alabama, Oklahoma, Arkansas, Missouri, Kansas, and Nebraska) saw record warm December's.[9] An early December heat wave set all-time record highs in Montana, Washington, Wyoming, and North Dakota. Parts of British Columbia saw temperatures of 22.5 °C (72.5 °F), tying it for an all time Canadian high in December.[10] In early-to-mid December, a major system produced a historic tornado outbreak along with wintry weather in the Upper Midwest, followed by another powerful storm that produced an ever larger tornado outbreak along with strong winds across the High Plains just a few days later. The storm, being a category 3atmospheric river event,[11] brought heavy rain and snowfall to the Western United States. Over 8 inches (20 cm) of rain during the storm were recorded on Mount Tamalpais, a mountain in the San Francisco Bay Area, with San Francisco itself receiving around two inches of rain from the event.[12] Around 60 inches (150 cm) of snow was recorded in Pinecrest, California.[12] The storm caused statewide snowpack in California to increase from 19% of normal to 83% of normal.[13]
Later that month and into early January, a series of winter storms brought a cold snap and heavy snowfall to parts of the West Coast, particularly areas in the Pacific Northwest region.[14] Several weather stations in Washington state recorded record-breaking low temperatures for December 26 and 27, with temperatures at 17 °F (−8 °C) in Seattle and 7 °F (−14 °C) in Bellingham.[15] This became Seattle's coldest day in 31 years, because the high for the day was only 23 °F (−5 °C).[16] Seattle recorded 9.2 inches (23 cm) of snow in December, exceeding the city's normal winter average,[17] while some parts of the region had more than 1 foot (0.30 m).[18] With five days of snow in a row, Seattle saw the most consecutive snowy days on record since 1969.[19] Another storm on January 6 led to the closure of several mountain passes in the Cascade Range, leaving only one east–west route across Washington. Snoqualmie Pass reopened to limited traffic four days later.[20][21] In Vancouver, British Columbia, the temperature dropped to −15.3 °C (4.5 °F) on December 27, the coldest temperature there since 1969.[22]
Before additional snow events occurred throughout January, with below-average temperatures being common, Falcon Lake, Texas, set a record
for the highest January temperature in the contiguous United States on January 1, at 99.0 °F (37.2 °C).[23] One such storm in January was the a significant winter storm in the eastern half of the country in mid-January with snow and ice,[24] causing Georgia, Virginia, North Carolina and South Carolina to all declare a state of emergency in preparation for the winter storm.[25] The most significant event occurred at the end of the month, when a major blizzard struck the Northeastern United States on January 28–29. This storm brought up to 1–3 inches (2.5–7.6 cm) across a swath of New England and caused widespread impacts. Blizzard conditions were confirmed at multiple locations in New England, including Providence, Boston, and Worcester,[26] in addition to some areas on the Jersey Shore receiving blizzard conditions. In early February, another major winter storm affected the country, with areas as far south as Texas to as far north as Maine receiving significant snowfall, though in the former it was not as bad as the previous year's storm which crippled the state's power grid.[27]Howard Pass, Alaska saw a wind chill of −91 °F (−68 °C) on February 7.[28]
The rest of February saw less significant wintry events aside from a few concentrated snowstorms in some areas, particularly the Northeast, but activity increased again in mid-March after a significant winter storm affected a wide swath of areas from Louisiana to Maine, dropping widespread snow amounts of 6–18 inches (15–46 cm).[29] After a few late-season cold snaps, a a major blizzard struck the Dakotas in mid-April, dropping as much as 40 inches (100 cm) of snow, unusual for so late in the season.[30] The last significant event occurred in late May after a record-late snowstorm struck Colorado just days after temperatures had been near 90 °F (32 °C).[31] However, on June 19, 2022, a hiker died due to hypothermia in Maine, and temperatures below freezing were recorded that morning in Canaan Valley in West Virginia, Mount Washington in New Hampshire, and Waverly, New York.[32]Caribou, Maine, saw their latest day where the high failed to reach 50 °F (10 °C), with highs of 49 °F (9 °C).[33]
On October 10 at 03:00 UTC, an extratropical cyclone made landfall near Vancouver.[34] This cyclone's remnants became a weak, elongated frontal system over the interior West Coast by October 11 at 12:00 UTC.[35] After remaining disorganized for about 12 hours, the system began to coalesce into a stronger extratropical cyclone over Colorado on October 12.[36] It also began to drop snow over parts of the Rocky Mountains by this point. The system then merged into a well-formed extratropical cyclone with a single-low pressure center by early the next day, beginning to steadily intensify.[37] Snowfall rates began to rapidly increase in bands to the west of the center throughout the day, with up to a foot of snow falling within hours. The system reached its peak intensity of 988 mbar (29.2 inHg) at 21:00 UTC on October 13.[38][39] The extratropical cyclone then began to accelerate to the north, becoming occluded in the process.[40][5] The weakening system then moved into the Canadian Prairies, resulting in some more snow there,[41] before merging into another frontal system on October 15.[42]
The precursor to the system resulted in blizzard conditions across parts of northeastern Utah on October 11, disrupting a 50-mile ultramarathon occurring there. Extremely heavy snowfall rates and winds gusting to tropical storm-force resulted in the race being called off, and over 87 rescues had to be made in the snow.[6] The next day, up to 6 inches (15 cm) of snow fell across mountainous areas of Colorado as the system was organizing.[43] The system also resulted in wind gusts of over 64 mph (103 km/h) in parts of Nevada that day.[44] On October 13, the system moved north into areas such as Wyoming, with 17.4 inches (44 cm) of snow falling in Casper, and even higher totals in the high elevations.[45] Additionally, hurricane-force wind gusts were recorded across parts of eastern Colorado and western South Dakota, with a 74 mph (119 km/h) gust occurring in Wasta. As the storm system reached peak intensity on October 14, heavy snowfall rates resulted in snowfall totals of over 2 feet (0.61 m) in parts of eastern Montana, with the storm's maximum snowfall total of 28 inches (71 cm) occurring in Pony. Larger cities such as Billings and Bozeman also saw 8–12 inches (20–30 cm) of snow from the system. Areas in the Black Hills such as Deadwood and Whitewood measured over 24 inches (61 cm) of snow, with Rapid City also recording 3 inches (7.6 cm).[5] As the system moved into south-central Canada later that day, it also resulted in some light snowfall there before the system dissipated the next day.[46] According to Aon Benfield, the system was estimated to have caused at least $50 million (2021 USD) in damages.[7]
In late October 2021, a powerful bomb cyclone struck the Western United States and Western Canada, bringing severe impacts to the region.[48] The cyclone tapped into a large atmospheric river and underwent explosive intensification, becoming a bomb cyclone on October 24. The bomb cyclone had a minimum central pressure of 942 millibars (27.8 inHg) at its peak, making it the most powerful cyclone recorded in the Northeast Pacific.[49] The system had severe impacts across Western North America, before dissipating on October 26. The storm shattered multiple pressure records across parts of the Pacific Northwest. Additionally, the bomb cyclone was the most powerful storm on record to strike the region, in terms of minimum central pressure. The bomb cyclone brought powerful gale-force winds and flooding to portions of Western North America. At its height, the storm cut the power to over 370,500 customers across the Western U.S. and British Columbia.[citation needed] The storm killed at least two people;[50] damage from the storm was estimated at four hundred million dollars (2021 USD).[47] The bomb cyclone was compared to the Columbus Day Storm of 1962, in terms of ferocity.[51]
In mid-December, a large storm complex produced a devastating tornado outbreak in the South. On the wintry side, a prolific snowstorm occurred within the Plains and Upper Midwest,[52][53] entering the Western United States on December 9. The storm brought the first measurable snowfall of the rainy season to Utah. In southern Wyoming and Colorado, the storm dropped a maximum total of 3 feet (0.91 m) of snow in the mountains.[54]
A nor'easter exited the east coast of the United States on January 4, producing snowfall from Alabama to New England, with as much as 6.0 inches (15 cm) accumulating in Huntsville, Alabama and 6.9 inches (18 cm) falling at Ronald Reagan Washington National Airport.[58][59] A peak snowfall accumulation of 15.5 in (39 cm) was recorded in Huntingtown, Maryland.[60] Many vehicles and motorists across Interstate 95 in Virginia were stranded due to the snow, with some of them for 24 hours. Over 1,000 motor crashes were also reported and assisted by the state's police. It also caused 3 people to die in a car crash in Maryland.[61] Two others died in the winter storm, one each in Tennessee and Georgia, bringing the total up to 5.[62] Snow even fell as far south as Fort Walton Beach, Florida, where temperatures dropped from 75 °F (24 °C) to 34 °F (1 °C).[63] Thousands of flights were canceled in the eastern United States.[64] At the Baltimore Washington International Airport, a ground stop was temporarily instituted.[65] This storm came after a day of record high temperatures; the temperature in Huntsville, Alabama the day before the storm (January 1) was 79 °F (26 °C), a record for January.[66] The winter storm was unofficially named Winter Storm Frida by The Weather Channel.[67] It also caused 343,000 power outages in Virginia and 42,000 in Maryland.[68] North-central, northeast and northwest portions of Georgia were placed under winter storm warnings by the National Weather Service there on 1 January.[69] Over 59,000 household customers lost electricity across Charlotte City, with 159,000 overall over the Carolinas. Some establishments were completely wrecked by the strong winds the storm brought, and trees were reported to have been downed.[70][71] This further rose to 211,000 by 3 January and lessened to 2,500 as rescue teams started working to restore electricity.[72] In Ellendale, Delaware, 14.5 inches (37 cm) of snow fell on 3 January.[73] This led to a chicken house collapse on 4 January which trapped a 12-year-old girl.[74] According to Aon Bonfield, damage from the storm reached $495 million.[57]
Farther north, in Iceland, news about the storm were dispatched across the country's people as a preparation.[75] The south and western parts of Iceland were also placed under an orange warning by the Icelandic Meteorological Office by 5 January.[76] The Icelandic Coast Guard also alerted vessels and fishermen in ports regarding the brunt of it.[77]Icelandair also canceled some flight operations by that day owing to the storm.[78] In the southwest portion of the country, rescue teams were reported to have been responding to the calls by the citizens there regarding the impact of the storm. Across Reykjavík, they responded to flying roofs of different houses and establishments. Suðurnes (Southern Peninsula) and Vestmannaeyjar (Westman Islands) were also severely affected. A hut was also blown away by strong winds in Vatnsleysuströnd.[79] The country's eastern portion meanwhile, was battered by rough waves from the storm. Harbours at Hafnarhólmur sustained "biggest" damages, as well as some vessels docked there. Rocks from the shores also pushed over the area's roadways; this was cleaned up subsequently.[citation needed]
Throughout the month of January, temperatures frequently were below-average in much of the Eastern United States. On January 11, the coldest air in 3 years came down on the Northeastern United States. The Interstate 95 corridor had wind chills dip below 0 °F (−18 °C), while it dipped in the -30s Fahrenheit in interior New York and Maine.[93] On January 15, the cold wave returned and strengthened, giving New York City the coldest day of the year, with a high of only 21 °F (−6 °C) and a low of only 10 °F (−12 °C), making the low the coldest reading in Central Park since January 31st, 2019.[94] This was after January 14 was slightly above average, with temperatures at 43 °F (6 °C).[95] In Syracuse, New York, the high was only 6 °F (−14 °C). January 2022 was Syracuse's first time in ten months having a below average month, and like in New York City, the day before had a slightly above average high of 36 °F (2 °C).[96]Burlington, Vermont had a wind chill as low as −32 °F (−36 °C) on January 15.[97] January 15 saw temperatures as cold as −44.4 °C (−47.9 °F) in parts of Quebec and −40.6 °C (−41.1 °F) in parts of Ontario. Toronto recorded a low of −21.1 °C (−6.0 °F), Quebec City recorded a low of −28.0 °C (−18.4 °F), Montreal recorded a low of −25.7 °C (−14.3 °F), and Ottawa saw temperatures as low as −26.8 °C (−16.2 °F).[98] A week later, Lopez, Pennsylvania recorded a low of −24 °F (−31 °C) on January 22.[99] That day, Canaan Valley, West Virginia set an all-time record low of −31 °F (−35 °C).[100]Quebec City tied an all-time record low of −36.7 °C (−34.1 °F) on January 22 as well.[101] On that day, several record lows were set, including Houlton, ME, at −25 °F (−32 °C), and Massena, New York, at −29 °F (−34 °C).[102]International Falls, MN had a frigid high on January 25, at just −7 °F (−22 °C).[103] On January 21, four Canadians froze to death just 40 feet (12 m) from the border with Minnesota with wind chill temperatures of −29 °F (−34 °C).[104] A fifth person died from a cold weather-related incident in New York, where the temperatures were −12 °F (−24 °C).[105] On January 21, an incident happened in a lake in Queens, when two people fell in the frozen lake, whereas the FDNY attempted to rescue the people that were stuck in the lake while using cold water gear.[106] In West Palm Beach, the city reached a low of 37 °F (3 °C), the coldest temperature recorded since 2010, and Vero Beach tied their 1978 record low temperature at 30 °F (−1 °C) on the morning of January 30.[107] Syracuse saw 8 days below 0 °F (−18 °C), the most in 7 years.[108] Parts of Cuba get as low as 3.0 °C (37.4 °F) early on January 31.[109] January 2022 became the fifth coldest January in record at Covington, Virginia.[110]
A weak area of low pressure developed on January 13 in southwestern Canada,[111] moving southeastwards into the High Plains while delivering heavy snowfall and began moving more southwards through the states of Nebraska, Kansas and Missouri into the early morning hours of January 14.[112] Later that day, at 21:00 UTC the Weather Prediction Center (WPC) began issuing periodic storm summary bulletins on the developing system, albeit with competing areas of low pressure.[113] Moving further south, a stronger low began forming over southern Missouri on January 15, moving into Arkansas and began strengthening due to a strong upper-level low located nearby.[114] Associated cold air in place over the aforementioned areas allowed snow to break out in areas further south, as the system began occluding later that night while wintry precipitation spread eastward towards the Southeastern United States into the early morning hours of January 16.[115] The system began turning more northward later that day into the southern Appalachian Mountains as the two centers began merging.[116]
Winter storm warnings and blizzard warnings were issued for large swaths of the Northeast and New England, as blizzard conditions were expected to occur closer to the coastal areas of the region.[126] Approximately 1,200 flights nationwide were cancelled ahead of the storm. New York governor Kathy Hochul on January 28 urged residents, particularly those further east in the Long Island region, to prepare for high winds, power outages and near-blizzard conditions.[127] People were also urged to not travel at the height of the storm. Hochul also ordered that state emergency assets be ready in case the system tracked further west.[127] A "snow alert" was declared in New York City by the New York Department of Sanitation that day as well. On Long Island, Public Service Enterprise Group crews worked to cut tree branches in order to prevent power outages from snow weighing down on the branches and breaking.[127] In New Jersey, major roadways such as Interstate 95 and Interstate 78 were being brined by the New Jersey Department of Transportation since January 26.[128] The agency also stated that potential drivers should check their car settings and be prepared should the urgent need to travel arise.[128] Officials in Atlantic City announced a parking ban would go into effect at 5 p.m. on January 28, in addition to opening shelters. In Boston, Massachusetts, officials warned of up to 30 inches (76 cm) of snow through early on January 30.[129] Early on January 28, a Blizzard Warning was issued for Rhode Island and eastern Massachusetts.[130] The state of Virginia declared a state of emergency on January 27 in preparation for the storm system.[131]
Blizzard conditions were confirmed at multiple locations in New England, including Providence, Boston, and Worcester.[26] Boston recorded its snowiest day in January on record, and also tied its all time one-day snowfall record with the North American blizzard of 2003, with 23.5 inches (600 mm) of snow falling.[132] Providence broke its all time daily snowfall record set in 1961, with 18.8 inches (480 mm) of snow falling.[133]
A widespread, damaging and severe winter storm affected a wide swath of most of the United States with widespread wintry precipitation, spreading from Texas all the way northeast to Maine in early February 2022.[134][135][136] Nineteen states in the U.S. received impacts from the system, with more than 90 million people that were in the storm's path.[27] The winter storm was unofficially named Winter Storm Landon by The Weather Channel and was also referred to by other media outlets as the Groundhog Snowstorm, primarily due to the storm impacting on Groundhog Day.[137][138][139]
The National Weather Service issued winter storm watches from Wyoming to Maine.[140] Winter Storm Warnings were also issued from New Mexico to Maine, and at least 18 states were under winter storm warnings.[141][142] In northeastern Ohio, and Buffalo, New York, snow amounts of more than a foot were forecasted.[143][144][145]Amtrak cancelled or modified the routes several trains due to the storm.[146][147]
A very large winter storm affected 265 million people towards the end of February. Portions of Interstate 5 in California were closed as a result of the snow.[157] Record breaking snow in Flagstaff, Arizona also forced a closure on Interstate 40.[158] In Wichita Falls, Texas, temperatures fell from 77 °F (25 °C) on Monday to the teens by Wednesday, with sleet falling.[159]Austin saw their largest 24 hour temperature drop on record, from 88 °F (31 °C) to 32 °F (0 °C), from Tuesday to Wednesday.[160] A fatal car crash in Tennessee killed one person.[161] There was also a child who died on a frozen bridge in Kentucky. There were also 52 injuries in Missouri due to a combined 402 car crashes. 33,000 customers in Arkansas, and 15,000 in Tennessee lost power.[162] The Missouri car crashes caused 4 deaths.[163] In the Northeast, temperatures fell from nearly 70 °F (21 °C) on Wednesday to the 30s Fahrenheit by Friday.[159] In fact, Bangor, Maine even set a record February temperature on February 23, 2022, at 65 °F (18 °C), and Islip, New York tied their monthly record high of 68 °F (20 °C),[164][165] although the monthly record in Islip would be broken on February 16, 2023.[166]Bath, Pennsylvania saw 0.6 inches (1.5 cm) of freezing rain, while Mooers, New York had 12 inches (30 cm) of snow, Madison, New Hampshire had 11.5 inches (29 cm) of snow, and Boston had 8.5 inches (22 cm) of snow.[167] A seventh fatality occurred in a 30 car pileup on Interstate 89 in Milton, Vermont.[168]
Mid-March winter storm and cold wave
A winter storm developed on March 9 as a shortwave trough over the High Plains and Midwest before moving eastward and dropping moderate to heavy accumulations across the region from March 9–10. It was unofficially named Winter Storm Quinlan by the Weather Channel.[169] On March 12, snow got over 10.0 inches (25 cm) in the interior and a dusting on the Interstate 95 corridor, and a 73 car pileup in Pennsylvania caused ten injuries.[29] Over 143,000 customers lost power.[170] Heavy snow in the Pittsburgh metropolitan area forced speed restrictions on Interstate 70 and Interstate 79.[171]Rockwood, Maine saw the peak of 14 inches (36 cm). Snow even fell as far south as Louisiana and Mississippi, but quickly melted.[172] High winds at High Point Monument reached 82 mph (132 km/h), faster than any gust during Hurricane Sandy at that location,[173] while in Ocala, Florida, a tornado touched down, which was rated EF1.[174] The strong winds also resulted in the upper level of the Verrazzano-Narrows Bridge being closed.[175]
Following that an arctic cold wave from Canada went as far south as Texas and Georgia, causing record-breaking low temperatures for the month of March in many areas in the eastern half of the U.S. However, before moving east, the arctic air also caused Casper, Wyoming to set an all-time record low for the month of March, at −25 °F (−32 °C).[176]Pittsburgh had a low of 9 °F (−13 °C) on March 13.[177] Parts of Wisconsin reached −8 °F (−22 °C).[178] Meanwhile, Jacksonville, Florida saw a record low of 30 °F (−1 °C). Wind chills dipped as low as 22 °F (−6 °C).[179] The lowest temperature in Tennessee during the event is −4 °F (−20 °C).[180]
Late March Northeast cold snap
A rare springtime cold wave affected the Northeastern United States at the end of March, following an arctic front moving in the night of March 27 into the morning of March 28. The high in New York City of 33 °F (1 °C) on March 28 is a record low high temperature, which was the coldest high temperature for Central Park this late in the year since April 7, 1982, when the high reached only 30 °F (-1 °C).[181][182] This is also lower than the typical high temperature in January, which is 39 °F (4 °C) January.[183]LaGuardia Airport, as well as Bridgeport, Connecticut, saw high temperatures as low as 32 °F (0 °C).[184]Philadelphia got close to breaking a record cold high temperature, with a high of 36 °F (2 °C) on March 28. The lows dipped down into the 20s for 3 nights, and winds gusted as high as 30 miles per hour (48 km/h).[185][186] In Stroudsburg, Pennsylvania, the high of 28 °F (−2 °C) was the coldest high temperature so late in the season.[187]Hamilton, Ontario had its coldest high on March 28 since 1923, with a high of only −4.7 °C (23.5 °F).[188] In Massachusetts, Boston tied a record cold high temperature of only 33 °F (1 °C), and in Worcester, the high only reached 27 °F (−3 °C), one degree below the previous record.[189] Wind chills in Worcester got as low as −1 °F (−18 °C) on the morning of March 28.[190] The wind chill high in Toronto only reached −16 °C (3 °F), and the actual high only hit −6 °C (21 °F).[191] The humidity was very low, with a dew point of 0 °F (−18 °C) in Lehigh Valley.[192]
Despite the low humidity, however, the cold wave also brought a snow squall, which, in Schuylkill County, Pennsylvania, caused a car crash on Interstate 81, killing six people and hospitalizing 24 others.[193] Despite 15 snow squall warnings being issued, none were issued in the area of the crash due a gap in radar coverage.[194] Then lieutenant governor and current senator John Fetterman tweeted out his condolences to the people affected in the crash and his gratitude to the first responders who dealt with the situation that day.[195]
In mid-April, a powerful late-season blizzard, unofficially named Winter Storm Silas by The Weather Channel, hammered the southern areas of Canada and North Dakota, dropping as much as 40 inches (100 cm) of snow in some areas.[30]
A very late-season winter storm, unofficially named Winter Storm Tad by The Weather Channel, affected the state of Colorado on May 20–21, 2022. A shortwave trough moved through the area, dumping up to 24 inches (61 cm) of snow in the state.[31] Some areas even received their heaviest snowfall for the month of May as a result, although Denver did not see a record-breaking amount. The winter storm followed on the heels of a large temperature drop throughout the state, following temperatures of near 90 °F (32 °C) the day before, with some areas like Denver seeing a 50 °F (28 °C) drop in that timeframe.[31] In Denver, as the front came through, the temperature dropped from 85 °F (29 °C), to 59 °F (15 °C), in 23 minutes.[217] The highest accumulations in Colorado were 11.4 inches (29 cm), while it was 11 inches (28 cm) in Montana.[218] The winter storm caused 100,000 customers to lose power.[219] In addition, over 600 flights were delayed and over 300 more were cancelled.[220] The low on May 21 in Denver was a record tying 31 °F (−1 °C).[221] While Wyoming did not see as much snow, several locations saw record low temperatures on May 21, and with a low of 26 °F (−3 °C) on May 22, Cheyenne also set a record low that day, although Cheyenne missed a record low on May 21. The second half of May was the coldest since 1951 in the area.[222] An MLB game between the New York Mets and the Colorado Rockies was postponed due to the intolerable conditions.[223]
A plane was damaged at the New Bedford Regional Airport after being blown off the runway. In Hingham, a large tree brought down wires.[228] According to Aon Benfield, damage was estimated at over $200 million (2021 USD).[231] The system would later move out to sea and acquire subtropical characteristics, becoming Subtropical Storm Wanda on October 31, later becoming a full-fledged tropical cyclone two days later. The precursor of Wanda caused a lot of flooding in the tri-state area with heavy amounts of rain, which killed two people. [citation needed]
