Ramen noodles - sorry to have missed your comments on me, I'm sure they were very informed and erudite - a bit like your knowledge of snow.

Snow can only form when there is an adequate supply of moisture (water vapour) that can condense into a water droplet and then freeze. The more water vapour there is, the bigger the snowflakes but there must also be freezing nuclei for the process to work. In the absence of the freezing nuclei, supercooled water droplets are formed and it is quite reasonable to have both SCD and snow, especially in the cloud from which the snow is falling.

Many icing limitations (ours included) specifically prohibit entry into cloud when it is snowing for exactly this reason.

At the moment in the UK much of the weather is mixed rain and snow (sleet in old money) falling from the same clouds so how can they be mutually exclusive?

BTW what exactly is supercooled ice?
