Yes, it's usually but not always cloud to cloud ... there have been cases of cloud-to-ground (CG) lightning strikes during snowstorms being particularly severe ... but usually it's just cloud to cloud ...
I've seen 4 thunderstorms with snow .
The first was with thundersleet and thundersnow Jan 15, 1988.
The next three was with Feb 16th, 1996 - the same ULL core which sparked the Blizzard of 1996. The first produced graupel (soft hail, snow pellets) and other two was all snow.
