Update on my "stranded motorist" status: Albuquerque was declared as being in a state of emergency because of the snow, and because of all the stranded cars & trucks. As I understand it, every shelter/hotel was full, and hundreds of people just had to sleep in their cars, but the authorities were handing out blankets and supplies and checking on people. For myself, I had enough friends and family in the area that I had a place to stay, and someone loaned me a 4-wheel drive so that I could get around town even though my own car was stuck.
This morning, we were finally able to get my car out of the snowdrift, though it took a fair amount of shoveling. I still have a lot of ice to navigate to get back to I-40, but nmroads.com is the most optimistic it's been in days:
