I think that might be a record.
My home weather station recorded a low last night of -20.4°C (-4.7°F). Whilst that's not the coldest it's ever been in Salt Lake City, it's certainly the coldest I've ever been here.
I started thinking about this last night. The temperature differential, (rounding to the nearest degree) is -20°C to +45°C here, from winter to summer. That's a 65°C difference in air temperature.
To put that into perspective, if it was water, at the bottom end it's well frozen, and even if it wasn't (like it was agitated water) you'd get near instantaneous frostbite if you put your hand in it. And at 45°C, it's hot enough to burn you.
Or to put it another way, if you adjust the scale so that the 65 degrees is all positive, that means the water goes from frozen to 65% of the way to boiling. No wonder we have central heating and central air conditioning.
