A few temperature records were set on Monday, Dec. 1.

It was due to westerly winds that brought in warm, dry air from the Pacific.

According to Environment Canada meteorologist Kyle Fougere, a lot of the moisture in the air was lost over on its way here.

"That's what brought all the rain to southwestern B.C. and a lot of snow to the mountain parts. Once the air loses that moisture, it descends on the eastern part of the Rockies mountains and warms as it comes down. That's where you get these really warm temperatures with chinook winds."

While Environment Canada's Okotoks weather station went down a few weeks ago, Black Diamond's hit a high of 14.6 degrees, a Dec. 1 record for the station.

The record for that day at the Okotoks station was 14 degrees, so it's very likely it was also surpassed.

As you can imagine, it's well above what we see at this time of year.

"It's stayed well above normal for this time of year over the last couple weeks, especially for the end of November. Our normal high for this time of year is around 0 degrees," says Fougere.

That looks to be coming to an end though.

"Unfortunately, those times are behind us. We've got a cold front sweeping through the province. Winds from the northwest are going to usher in cold air across the province. So we're going to get back towards what's more normal for this time of year. By the time we reach Monday morning, we'll have an overnight low of -15. So the warm air that has been in place is, unfortunately, going to be replaced with colder air from the north as it slides down the province."
