CityVal (you're only mentioning it because I pointed out I was excited for its launch in Rennes in a couple of years, a few pages ago), and it's predecessor VAL, aren't built in places with snow.
As for the comment about it running "mostly outside" - there is no relationship between the guideway alignment/type of grade separation and the technology. It can be underground, elevated, or at-grade - your choice.
Morgantown's PRT is about the only [rubber-tired] AGT system I can think of that operates in an area with regular snow, and there, the entire guideway is heated (at great expense). The upshot is that it always works, even when the roads are completely impassible...
