What confuses me here is that he says the storm is "collapsing" and all the wind aloft is coming to the ground but...why would extratropical transition cause that? I would assume if the storm collapses that means its dying, but it's not.
Descending/drying air will bring down some of stronger winds aloft to the surface (and enhance them a bit due to the gravitational acceleration as it descends).
