If it were mine, and in your weather as you describe it, I will keep the plants indoors just for another month more. It would be sad to be blindsided by the cold and wet combination after all the effort of keeping them alive indoors the whole winter season. Unless, you have a patio overhang that can reasonably keep them dry while it is cold, then it is okay to bring them out. But otherwise, the plants will suffer cold damage on the tissue level leading to rotting.
