American here, I agree, our anachronistic measurement systems and twisted pride in them is insane (but insanity is perfectly normal here).

In the lower Midwest it is currently -22C (-8F) in Kansas City and Chicago. In the upper Midwest it’s about -25C (–13F) in Fargo, North Dakota and 27C (-17F) in Billings, Montana.

Temperatures are usually 10-15 degrees C higher this time of year, so this weather is quite dangerous.
