Just how cold did it get on Friday morning? Record-breaking cold.

The temperature dipped down to -21.8 C at around 8 a.m., beating out the previous record for Jan. 3 by a sliver.

The previous all-time low for Jan. 3 was -21.6 C, recorded in 1981.

With the wind chill, it felt as cold as -32 C in the morning, but temperatures rose later, reaching around -15 C by 2 p.m.

Hamilton’s bone-chilling morning came amid a deep freeze for much of Ontario.

“We’ve seen records broken right across the province, but it seems like Hamilton has joined that group in the past few days,” said Geoff Coulson, an Environment Canada meteorologist.

The weather service issued cold and wind chill warnings for most of Ontario and Atlantic Canada for Friday morning

Many people in the Atlantic provinces also had to contend with a blizzard Friday in addition to wind chills that were forecast to ebb to as low as -35 C.

A cold air mass settled in early this week but many people may see some relief from the cold starting this weekend.

But for Hamilton, a return to more seasonal temperatures comes with a catch.

On Friday afternoon, Environment Canada issued a special weather statement for Hamilton, warning of a snowstorm that's in the forecast for Sunday.

The Hamilton area could see between 15 cm to 20 cm of snow and high winds, the agency says.
