Morphology
The literal meanings of 'cold', 'day', 'in' and 'Hell' are clear, and the contradiction between 'cold' and the culturally expected heat of Hell can signal impossibility to a learner. However, this is a conventional idiom relying on cultural knowledge and figurative inference rather than straightforward compositional meaning, so while its sense (extremely unlikely) can sometimes be guessed, it is not fully predictable for a B1 learner without prior exposure.
Etymology
Cold day in Hell uses the sharp image of Hell—a place thought to be always hot—so a cold day there would be impossible, and that picture makes the phrase memorable. So people say it to mean 'something is extremely unlikely' or 'will never happen'.
