Well, you beat me to it - with one wrinkle - I think that what you are seeing now is more of a very well formed and mostly mid-level circulation and that the surface vortex (now rather weak) is located to the SSE. But your analysis seems sound. During the night, northerly shear displaced the convection and perhaps the surface low to the south. Since the system was/is only a TD, its quite likely that the two circulation centers never were fully coupled. Remember that trough off the west coast of Africa that Clark mentioned in his blog? Well that was probably the real culprit for the northerly shear. At any rate the system seems to be heading off to the west northwest again and the shear is less evident, so I'd expect TD9 to regather some convection again. I doubt that the system will fall apart since the circulation envelope is large, but any intensification will take a day or so.
