Icing conditions may exist if there is visible moisture and the temperatures are correct for icing to occur.
But the keyword is visible moisture and whether there is snow there or just plain rain is irrelavant.
You should fear taking off into rain with no snow equally as much if the temperatures are in or near freezing.
The danger of implying otherwise is some poor S*D is going to tremble in his boots because of snow being present but happily take off into rain.
Snow looks cold and icy but its the temperature he should be looking at and the visible moisture not the snow.
