The most remarkable part of February was how persistent the cool pattern was. The first shot of arctic air was probably the most anomalous, at least at the surface, and it was relatively brief. We just really struggle getting those low level cold outflows nowadays, which is why we struggle to see those -10c lows at YVR

I wonder how much downsloping will be a factor before the brunt of the cold air arrives. It was -5 in Lytton and -10 in Kamloops at 7am. It'll probably be like last week: nominal heating by compression followed by nominal cooling. (I wonder if Nitro is still calling for +8 to +11). On that note, has anyone seen the temps in southern Alberta this am? Flirting with -40 over there.
They had to bump up today's forecast high for Abbotsford from 2C to 6C. I thought 2C was pretty pessimistic considering the cold air only started moving in around 4 am this morning.

For where exactly?
That’s not true for any of the longer running stations. 3rd coldest at Shawnigan Lake. ‘36 and ‘89 were significantly colder with more impressive arctic airmasses within the month.
It was a touch colder than '89 on the mainland, but that year certainly had more impressive lows. We didn't even manage -10C this February, which is truly odd for such a cold month.
But there's no question we had colder Februaries before the airport era.

Actually, this month of February was obviously very cold overall but the cold was moderate and persistent; there was no harsh cold.
I think we are saying the same thing. Persistent cool/cold but no major arctic outbreak.

Interesting. ‘89 was 0.9C colder here. Mostly made up of colder low temperatures. -4.5C in ‘89 and -3.0C in 2019.

The '89 event was insane. Most locales had sub -10C highs with that arctic blast!

Yeah 1989 was way colder than anything we've experienced this month. In fact, outflow winds were stronger and persisted longer in 1989 as well. 3 days of 90+ km/h gusts and 2 days with -15C lows. Here's the stats for Abbotsford at YXX:
