flying in snow

In a typical spam can (say an archer), which has no deice at all (save pitot
heat), is it safe to fly in snow? More generally, of course the snow will
bounce off and not stick to the wings (right?) but what about the clouds that
are producing snow - will they also produce airframe ice? If it's above
freezing on the ground, and the clouds are very high, and it's snowing, then as
I climb I'll (yes?) climb above the freezing level - is there danger in that
transition when it's snowing? (I presume there's no freezing rain or sleet,
else I'd see it on the ground, no?)
