I've weather courses numerous times (military navigator, civilian pilot) and the only freezing fog or rain I'm familiar with is that which freezes to a below freezing object when it contacts that object (like the leading edge or a wing or prop.
Never saw fog at 30F or lower and I know at 0F there is no moisture in the air. At the negative 29 we played in the environment was drier than the sahara.
Just because I haven't seen it doesn't mean it can't exist but everything I've been taught tells me that very close to freezing it's possible to have transitioning moisture but 3 degrees would have to be pushing it. I could be wrong, but I'd need a scholarly journal, bonofide weather course or science manual.
We've done so much, for so long, with so little, that we can now do the impossible, overnight, with nothing.
