Yeah, I've got a planet like that that needs a lot of fleshing out. Mostly figuring out the weather patterns.
What I'd *like* is for there to be enough atmospheric circulation to keep the "hot pole" not *too* much worse than the deep parts of the Sahara (if it's land). And the cold pole not too much colder than the colder parts of Antarctica.
Rising air at the hot pole sucks in air from areas around it. The rising air flows away from the hot pole at upper levels and sinks at the cold pole.
It might be possible to have several rising/sinking flows in rings around the hot & cold poles. But that would mean the temperatures wouldn't be moderated as much except in those rings.
I want global circulation because it'd not only even out the temps a fair bit, it'd also get water transported.
Of course, once you have enough ice at the cold pole it'll flow towards dayside. Unless it gets too cold to flow.
While Coriolus force will have an effect on the circulation, it will be *much* less than on earth due to the slow rotation of the planet (once a year).
I have a scene where someone new to the planet has been outside for *hours* and asks how long it is til sunset. Someone who's been there long says "About three thousand miles. I think the closets part of the terminator is *that* way..."
Of course, I'm having the planet orbit a brown dwarf which throws in a lot of other fun "local color".
