Snow can be VFR too, but you need to be careful as that can change quickly. Good rule of thumb when flying VFR is never fly into a shower if you cannot see through it to the other side. Flying in snow is the sort of thing you need to do first with somebody who has done it before. Better to pick your way around the showers if you can. Ice can happen, snow can be 'wet', apply same rules as when flying in rain.
