Daily and all-time temperature records are expected to be broken over the coming days as a "heat dome" settles in over Western Canada, from British Columbia into Saskatchewan and up into the Northwest Territories and Yukon.

Last week, CBCmeteorologist Johanna Wagstaffesaid that heat dome is what is expected to breakrecords.

"Sinking air will push down on the air near the ground, basically like a pressure cooker," Wagstaffe said.

"That high is not going anywhere anytime soon."

And climate changes means such trends are not going away anytime soon, Wagstaffe said.

"We're breaking some very old records, and that's always an indication of climate change," she said. "But also we're breaking records from just a couple of years ago.

"And every time we see records that are quite new, it means our baseline is shifting."
