I guess there are two important things to understand:

Snow is a great insulator.

Liquid water has a lot of stored thermal energy (as does the ground).

Anecdotally I can recall sleeping in a snow cave at -30F and being a toasty +30F on the inside with only a candle lantern and my heavily insulated body as heat sources.
