(It occurs to me that "smells like snow" mostly means "smells like impending/approaching snow" more than it smells like snowfall. Sometimes it still smells like that while the snow is falling, and sometimes it doesn't. Someday I'll figure out exactly what it is we're smelling when we use that phrase.)
I think we're "smelling" a combination of still weather, low clouds with the associated pressure level, and the right temperature---not very far from 0 C.

I think you're right, though possibly the "smells like snow" combination also includes the right level of humidity.
