While the near-term shear level is low and by itself would not hinder intensification, as noted above, the verticle displacement of the current cyclone is considerable - probably around 70NM between the low-level and high-level circulation centers. This displacement with height to the south would take quite some time to vertically align. Even if the dry air was not a factor it would be difficult for the system to have enough time to align in the vertical prior to landfall.

Its worth noting that the windshear is expected to increase considerably (admittedly from a GFS product) between tonight and Friday morning (time-sensitive link) although the near-shore windshear should be lower:
