For the storm potential for around the 5th- plenty of spread among the members, from crushed south to a track much further north. The outcome mostly hinges on the amplified Hudson ridge and how strong of a vortex gets caught underneath as the anticyclonic wave break occurs. If that vortex is displaced southward of 50-50, the wave moving eastward in the southern stream will tend to be suppressed southward or dampen and weaken as it comes east. If that vortex is weaker/further north, the shortwave can track further north. At this juncture, well ofc we just cant know.
The disparity among the members can pretty clearly be seen in this panel-
