Read "extreme" as "normal summer heat wave".

"Heat Dome" "Atmospheric River".... sounds so scary!

[alexfrancois]

Is there a way that we can pay more tax to avoid this?

[lorelaigilrour]

Im shocked they havent demanded we stay home to flatten the dome

[webmario]

STOP!!!! It’s summer! Every summer we have heat waves, nothing new!

[WhirlyPearly]

As central and southern Alberta is 17 c, crazy weather

[MrDavidwilson]

Also make sure to eat food, it takes energy to sweat.

[kefs]

Don't forget to take long cold showers for hours! Especially in Calgary!

[billclay]

Hopefully the smell doesn't travel west

Meanwhile it was snowing in Canmore June 17th

You could be in Alberta with a polar vortex causing low temperatures with lots of wind! We’ve not had more than 3 days of summer weather.

It's late fall/early winter weather out in Vancouver.

I am in southern Ontario living in this with no air conditioning. I am sitting here typing this in my home with all the windows open enjoying the breeze

[Damien-Infinity]

[Dracoool]

Its called "SUMMER"....enjoy it while it lasts.

On the lower mainland, Vancouver Island we get lower 30-35 regularly during the summer. When we had our heat dome a few years ago we had in the 40'ies

[jimmyarbutus]

Before this feller described what a heat dome was, I was living like an animal, saying things like "sure is hot out today' and it'snot the heat...it's the humidity. I feel like such a fool.

[SylviusTheMad]

Calgary and Edmonton both have frost advisories today.

[thegreatplague]

Uh oh.

I best travel to a warmer climate for my vacation since it looks like a cold summer, again.

We have taken to sleeping on our basement parlor. It is so cold down there we need our flannel sheets!
