You're not kidding!! From 40°C in mid July down to -50°C only five months or so later is about as crazy as you'll get on this planet.
Not even close. In our Province we have this little thing called a Chinook.
Canada's Biggest Temperature Change in One Day | Reader's Digest (readersdigest.ca)
Pincher Creek, Alberta, is located about 200 kilometres south of Calgary and holds the
national record for the biggest temperature change in one day. According to reports, on January 10, 1962, the temperature rose from a chilly from -19 C to a balmy 22 C—in just one hour. That’s an increase of 41 degrees (or roughly two-thirds of a degree
per minute)!
Certainly not a
typical Chinook wind, but I have seen overnight temps climb fairly rapidly, and in the dead of winter most folks welcome the sudden change.
What I haven't experienced, is the extreme temps that we now see on a more regular basis, lasting numerous days, or weeks. Ditto to the resulting wildfires, and the smoke that these massive fires produce. Up until 6-7 years ago, the number, and size of the wildfires didn't create air quality issues locally, let alone clear across the country. Now for us at work, it's become a seasonal thing. Merv 13 filtration and/or 100% damper closures in our HVAC systems during wildfire season.
People can attach whatever name they like, all I can say is it's certainly outside the norm.
