I am in Arizona, Phoenix area. However, nothing compared to Chicago. The windchill factor got to -60 below and worse.
But I learned a thing when I moved down here. The winters here are mild in comparison, but it really does not matter. When you have months of heat in the double digits, when it drops down to even the 40's, it is FREEZING in comparison.
Imagine it being 110 degrees outside and having to go into a grocery store that is air conditioned to where it is about 75 degrees? That is a 35 degree drop in temperature in a matter of seconds. You can get very sick that way. I always bring a sweater to go shopping.
So, when it goes from say 90 degrees and then drops to 40 degrees, and damp? It is flu season. I have been sick now for a week and want to just end it all. This really sucks. I got sick because I work in a dump that thinks it is a good idea to turn on an air conditioner when I am trying to work and keep the client WARM.
What the heck sense does that even make? It is cold outside and they turn on the air? WHY? So we can all get sick and stay home?
I just wonder where these idiot's heads are at that run this place.

You've never been to a desert, have you? In summer you wear a long sleeve white shirt, unbuttoned, over a cotton tee shirt. Poly/cotton pants large anough that you need suspenders to hold them up. (Not a belt.) And cheap sneakers. You don't smoke in the daytime, and you don't talk much.
In the evening, if the air is warm, you take off the long sleeve shirt and maybe wear a wet towel around the neck. A smoker might smoke an entire pack between sundown and midnight, and talk up a storm while doing it.
"A cool clear night in the desert, with a temperature of 5°C and a relative humidity of 5%. The modified Swinbank formula yields a flux of 198 w/m2, which in turn corresponds to a black body temperature of -29.9°C or a gray body temperature of -10.9°C."
