Forget about wind chills. The coldest night I ever experienced had an ambient air temperature below -30. It’s amazing what happens to a car and a human body at that temperature.

air temperature below -30

I saw it -30 one winter morning in Gunnison Colorado. It was cold.

I've seen ambient air temps down to -40. Honestly, I didn't think they were all that bad - no wind. Everything froze solid, though. When it's dead still like that, you can breathe out and the frost just hangs there in one spot, for a long time.

Coldest I've ever seen was up in Nova Scotia. Temps weren't all that bad - single digits and teens - but the wind came right off the North Atlantic. Literally took your breath away, the feeling was shattering. Worse than anything else I experienced, didn't matter how well you dressed for it, nothing was warm enough.

Living in the Southeast is better, temps might get down to 20 tonight; everyone is whining about the bitter cold. Will be back up to 60+ next week....

One winter I drove from Fairbanks to anchorage at -32. You worry about a breakdown under those conditions.
