Bitter arctic cold Sunday morning shattered temperature records on the Prairie of Alberta, where the city of Edmonton is bracing for another night of extreme cold.
The overnight low temperature at the Edmonton International Airport was -51 F, or -46.1 C, cold enough to set a new low mark for Dec. 13.
Moreover, it was among the coldest mornings in city history. Lows down to -55 F have been registered in December at another site, the airport at Blatchford Field. The readings of -56.9 F reached elsewhere in Edmonton on the 19th and 21st of January, 1886, still stand as lowest overall in the city.
Sunday night, the temperature will nosedive once again with readings by daybreak, Monday, bottoming at -30 F to -40 F across the city. For perspective, the normal low temperature on the 12th to the 14th would be a bracing 3 F, a virtual heat wave next to this brutal weekend cold.
Edmontonians and Albertans as a whole can look forward to a break in the arctic chill as warming wafts in from the Pacific Ocean at mid- to late week.
