The February 2021 North American cold wave was an extreme weather event that brought record cold temperatures to a significant portion of Canada, the United States and parts of northern Mexico during the first half of February 2021. The cold was caused by a southern migration of the polar vortex, likely caused by a sudden stratospheric warming event that occurred the prior month. On 7 February 2021 Uranium City, Saskatchewan, equaled their all time coldest temperature of −48.9 °C (−56.0 °F) previously recorded on 15 January 1974. In Winnipeg, Manitoba, the high temperature did not rise above -20.0 °C (−4.0 °F) for 9 consecutive days, the longest period since 1996. On 7 February 2021, the International Airport weather station in Edmonton, Alberta, recorded a low temperature of -43.6 °C (−46.5 °F) with two consecutive lows below -40.0 °C (−40.0 °F).
