I just read this in article for icing on airplanes
the question that I ask myself on reading this document, is it possible that droplets of a certain size remain in droplets above 100C?

The droplets remaining in the liquid state at temperatures below the freezing point are said to be supercooled. While cooling, they do not systematically freeze at 0º C. There is however a limit to their cooling without there being freezing, a limit depending mainly on the size of droplets.
The larger ones freeze at temperatures slightly below the freezing point, while the smaller ones can remain liquid down to -40º C. Below this temperature, they are rare.
An supercooled droplet freezes at the slightest shock, that is to say the moment it touches the device. The latent heat it gives off immediately increases its temperature. If the temperature of the droplet was not too cold at the start, it will increase until it reaches 0º C.
