Meterology of double planets sharing an atmosphere

If two planets were tidally locked and shared an atmosphere, as described in this question, what would the weather patterns of the planets be like? What weather patterns would form, and could these weather patterns travel from one planet to the other?

For the sake of simplicity, assume both planets are Earth-like in composition and mass, with high amounts of water on the surface, liquidy interiors, metal cores, humid oxygen/nitrogen-filled atmospheres etc. One can assume that the planetry pair are about the same distance from there star (which is of the same type as the Sun) as Earth is from the Sun.
