At approximately 1.5 km up in the atmosphere, the coldest temperatures in the world are over Hudson Bay and headed for the US. Looking at the lower atmosphere rather than the surface temperature (mostly) removes the influence of elevation. The temperatures are shown in degrees Celsius on the 850 hPa pressure level, which is approximately 1.5 km above the surface.

I live in Colorado, at approximately 1600 m elevation (so slightly higher than shown here). I'm sure that wave of -40C won't lead to those same temperatures here, but how does elevation play a role? Do these temperatures then appear at 1500+1600=3100 m elevation?
You know how when you check the temp it says "feels like" a lower temp? Being at ground level changes that so the elevation makes it more unbiased because humidity and wind
