Reply to comment by ordinary_kittens in ELI5 Why are airport ceiling so high? by TrShry

I've lived in MN my whole life and the coldest I remember was a few overnight lows of -30F during a polar vortex. I think some areas in greater MN might have hit -40F here and there but it's certainly not routine and doesn't stay that cold very long. Anything lower than say -10F is not common and usually only for a few days to a week or so.

Yeah, people in Canada tend to exaggerate by giving the windchill temperatures, but I think that’s cheating. Excluding windchill we don’t really get to -40F/-40C very often, maybe only once or twice every second winter, in the middle of the night during a cold snap, like you said.
