Steve, my car has performance tires on it, terrible in snow. It has sat incased in ice at below zero and sub freezing for over a week and it's okay. My grandson left me rear car door ajar two weeks ago and the battery was dead, but my son put the charger on it. I thought for sure the battery wouldn't turn over yesterday in single digits but it did fine. I don't use washer fluid in my window washer fluid, I put in antifreeze type stuff and the radiator has antifreeze in it.
So if only I had snow tires I could go someplace.

No, this cold I try not to go out. I do have to work on Monday, we will take my husbands car as it has four wheel and I'm working in the Poconos. It's back an off road lane, and will be single digits. Yuck!

Hope all is well, and the warm up melts away the mess tomorrow for you. Still snowing up here, but it will go above freezing, I pray.
