Ok, so it's snowing out. Presumably the water in the clouds is all frozen and
there should be no icing concerns. Under what circumstances am I wrong?

If it is snowing dry snow and the temp is well below freezing you can
pretty much discount ice if you remain clear of clouds. The snow may
clog the air intake, but ice will not accrete on the leading edges.

If you get up into clouds, however, regardless of whether snow is
falling below the clouds, you should probably be prepared for ice
accretion because in the clouds the water will most likely not be
completely frozen, unless the temperature is VERY low and you will
encounter supercooled droplets which will freeze when they hit the
airframe.
