Just to clear up a few points i think there is confusion as to what snow is what sleet is and what rain is? Snow is NOT sleet but a specific structure of dry ice particles which contain NO moisture. the particles are so fine that any warming converts those tiny structures into water and ice but that is NO longer snow.
You may see what appears to resemble snow to the pilot but it is likely to be sleet.
Yes if there is a mixture of rain ie visible moisture and snow flakes the rain can form ice but that is the case regardless of the snow.
Dont really want to start this one up again but if anyone can explain the science of snow forming ice please feel free
