That would be as windy as Contrevent
YMMV, since it's all opinion and conjecture right now.
But in general I wouldn't expect much wind. The hot side is in vacuum because the only volatiles there are the ones just baked out of the fried ground or perhaps some volcanic activity, and the cold side is in vacuum because everything's frozen, and if there is some tiny pressure gradient you'd never notice the resulting "wind" as the vacuum flows past you, probably at rates roughly comparable to what the ISS experiences as "wind" in its low Earth orbit.
