You know I'll always call you out when you say it never gets too cold.
Last winter was a warmer-than-normal winter for Denver. Yet, 54 nights last winter fell into the teens or colder. 13 of those were in the single digits. Six were below-zero. Including a 15-degrees-below-zero morning.
17 daytime highs never got above the freezing mark.
I do know cold doesn't tend to last long, as when the wind shifts direction, it can easily be in the 60s mid-winter. But it does get darn cold there on occasion. It's not a Wisconsin winter -- but it's closer to Wisconsin-like than it is Arizona.
Maybe you just have much thicker blood than me!
