2021–22 North American Winter

The 2021–22 North American winter was not as significant and record-breaking as the previous winter season. Despite this, several notable and significant events still occurred, including two separate record-breaking tornado outbreaks in mid-December, a significant winter storm in the South in mid-January, a powerful blizzard that impacted the Northeast coast at the end of January and a wide-ranging, significant winter storm that affected most of the eastern half of the country in early February. Additional significant events included a late-season winter storm in March that affected the Appalachian Mountains, and a major blizzard that affected North and South Dakota in mid-April. Additionally, a very late out-of-season snowstorm struck the Rocky Mountains in late May. During the season, four storms have been ranked on the Regional Snowfall Index (RSI), although none attained the “Major” category. Similar to the previous winter, a developing La Niña was expected to influence weather patterns across the continent.

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. Based on the meteorological definition, the first day of winter started on December 1 and the last day was February 28. 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

On October 13, 2021, The Weather Channel (TWC) released its U.S. winter temperature outlooks for the 2021–22 winter season. 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.

On October 21, 2021, the National Oceanic and Atmospheric Administration's Climate Prediction Center released its U.S. Winter Outlook for the upcoming winter. 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 Southwestern United States, 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.

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 across much of the Intermountain West and over 80 rescues due to blizzard-like conditions in Utah. The system was estimated to have caused at least $50 million in damages. 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. 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.

Events

Mid-October winter storm

On October 10 at 03:00 UTC, an extratropical cyclone made landfall near Vancouver. This cyclone's remnants became a weak, elongated weather front, frontal system over the interior West Coast of the United States, West Coast by October 11 at 12:00 UTC. After remaining disorganized for about 12 hours, the system began to coalesce into a stronger extratropical cyclone over Colorado on October 12. 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. 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 at 21:00 UTC on October 13. The extratropical cyclone then began to accelerate to the north, becoming occluded in the process. The weakening system then moved into the Canadian Prairies, resulting in some more snow there, before merging into another frontal system on October 15.

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. The next day, up to of snow fell across mountainous areas of Colorado as the system was organizing. The system also resulted in wind gusts of over in parts of Nevada that day. On October 13, the system moved north into areas such as Wyoming, with of snow falling in Casper, and even higher totals in the high elevations. Additionally, hurricane-force wind gusts were recorded across parts of eastern Colorado and western South Dakota, with a gust occurring in Wasta, South Dakota, Wasta. As the storm system reached peak intensity on October 14, heavy snowfall rates resulted in snowfall totals of over in parts of eastern Montana, with the storm's maximum snowfall total of occurring in Pony, Montana, Pony. Larger cities such as Billings, Montana, Billings and Bozeman, Montana, Bozeman also saw of snow from the system. Areas in the Black Hills such as Deadwood, South Dakota, Deadwood and Whitewood, South Dakota, Whitewood measured over of snow, with Rapid City, South Dakota, Rapid City also recording .

Late October West Coast bomb cyclone

In late October 2021, a powerful explosive cyclogenesis, bomb cyclone struck the Western United States and Western Canada, bringing severe impacts to the region. The cyclone tapped into a large atmospheric river and underwent explosive cyclogenesis, explosive intensification, becoming a bomb cyclone on October 24. The bomb cyclone had a minimum central pressure of at its peak, making it the most powerful cyclone recorded in the Northeast Pacific. 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 atmospheric pressure, 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. The storm killed at least two people; damage from the storm was estimated at four hundred million dollars (2021 USD). The bomb cyclone was compared to the Columbus Day Storm of 1962, in terms of ferocity.

Mid-December storm complex
