The southwestern United States experienced a rare winter blizzard in December 2021, causing record-breaking snowfall, low temperatures, and travel disruptions. The blizzard resulted from a collision of cold air from Canada and moist air from the Pacific. The storm disrupted transportation, caused power outages, and increased demand for emergency medical services. While some residents were prepared for the snow and cold, others were caught off guard. It is possible that the blizzard provided some relief for drought conditions in the region. As extreme weather events become more frequent, it remains unclear how often events like this will occur in the future.

Snowy surprise in the desert: Rare blizzard blankets southwest

Residents of the southwestern United States were treated to a rare sight in mid-December 2021 when a winter blizzard brought snow and cold temperatures to the normally arid region. From Arizona to Texas and New Mexico, people woke up to a winter wonderland that seemed out of place in the desert environment. The storm set records for snowfall and low temperatures in some cities, and caused chaos on roads and highways.

The Blizzard

The blizzard that hit the southwestern U.S. on December 15, 2021, was the result of a cold front that moved down from Canada and interacted with a moist air mass from the Pacific. The collision of these two air masses caused heavy snowfall, high winds, and low temperatures across the region. Some areas received more than a foot of snow, while others saw record-breaking low temperatures. Phoenix, Arizona, for example, experienced the coldest December 15th on record, with a low temperature of 22 degrees Fahrenheit (-5 Celsius).

The blizzard disrupted travel and caused power outages across the region. Flights were delayed or canceled, and many highways and roads were closed due to the snow and ice. In some areas, snowplows and salt trucks were not available, as such equipment is not typically needed in the desert. Some residents were prepared for the cold and snow, having purchased snow shovels and winter clothing in advance. Others were caught off guard by the sudden change in weather, and many schools and businesses closed for the day.

The Impacts

The winter blizzard had a variety of impacts on the southwestern U.S. region. Some of the most significant impacts were:

• Transportation Disruptions: The snow and ice caused significant disruptions to transportation across the region. Many roads and highways were closed, and flights were delayed or canceled.
• Power Outages: As temperatures dropped, demand for electricity increased. Some areas experienced power outages due to increased demand and downed power lines.
• Cold-related health issues: Exposure to low temperatures can cause a variety of health issues, including frostbite and hypothermia. Some hospitals and emergency rooms reported an increase in patients with winter-related health issues.
• Financial Impacts: The blizzard had financial impacts on businesses and individuals. Many businesses were forced to close for the day, losing revenue. Some individuals had to incur unexpected expenses related to winter weather, such as purchasing snow shovels or hiring snow removal services.
