Western Canada well into the deep freeze

If Western Canada is not the coldest place on Earth right now, it's got a pretty good claim.

Westerners from Manitoba to Alberta woke up Saturday morning to temperatures down to -40C, but made much worse by a windchill that's making it feel as low as -50 in some places.

It's due to a Rex Block pattern - a weather phenomenon where a high pressure area and a low pressure area are parked beside each other.

The effect is almost like a conveyor belt for cold Arctic air, which is pouring into the region.

Don't expect much relief for a little while, says Matt Grinter, a meteorologist at The Weather Network.

"They're not looking at temperatures like this for all next week, but they will be well below seasonal," he said Saturday morning.

Parts of Alberta will see a slight but still well-below seasonal warm up on Monday, before joining Saskatchewan and Manitoba in the deep freeze for at least the next week.

Friday was hardly warmer, with average high temperatures in the mid-negative twenties common - colder, in fact, than Churchill, Manitoba, on the shores of Hudson Bay, and Yellowknife, the Arctic capital of the Northwest Territories.

Eastern Canada is cooling down too, although the big thing for the region to look forward to is snow, rain and winds, beginning Sunday.

TUNE IN: We'll be following that system for the whole weekend. Watch The Weather Network on TV for updates.
