I wouldn't go as far as saying "if at all". This is very likely to form into a coherent, albeit broad low. Pressures have been slowly falling (now down to 1005-1006MB).
The mid-upper low/trough causing the shear was never really forecast to dissipate or get out of the way by the model guidance for most of the system's existence. And while it certainly is limiting the speed with which the system is organizing, the resultant shear over the formative system is *highly* divergent, and I do mean highly. All along, the model guidance has suggested this will be a BE type system with significant evacuation of mass aloft being the primary mechanism for lowering pressures during it's formative process. This has always been advertised to be a broad sloppy "right-sided" system, but still intensifying (in spite of the shear) due to the aforementioned BE.
