Edmonton breaks weather record for coldest December 13

Sunday marked the coldest Dec. 13 in Edmonton’s history.

Environment Canada recorded a frigid -46.1 C, or -58.4 with wind chill, at the Edmonton International Airport at 5 a.m., Environment Canada meteorologist Pierre Lessard said.

The old record of -36.1 C was set last year, he said.

“To break a temperature by 10 degrees is very exceptional,” said Lessard.

A ridge of frigid Arctic air has hit all the prairie provinces this weekend, causing record-low temperatures in many parts of northern Alberta, Lessard said.

“Temperatures are very cold over Alberta, Saskatchewan and Manitoba. There are some places more windy than the others, especially northern Saskatchewan and the north half of Manitoba are very cold,” he said.

But Arctic winds are normal in the winter and should pass through by the middle of this week, Lessard said.

Some flights scheduled to land at the Edmonton International Airport late Saturday night and early Sunday morning were diverted to Calgary because of the severe temperatures, said Edmonton International Airport spokeswoman Traci Bednard.

There were some delays and a couple of cancellations for flights departing Edmonton as well on Sunday morning because of the cold, she said.

“Different airlines and aircrafts have different operating limits,” Bednard said.
