The polar temperatures hit all 50 states of North America, with temperatures below freezing being measured even in Hawaii, where a temperature of 20°F (-7 °C) was recorded at the top of the dormant volcano Mauna Kea.
The bizarre cold in the US and Canada led to record temperatures of -20°F (-30 °C), and windchill gave the feeling of -60°F (-50 °C).
