The vapor image around 0400 still showed both walls.
That vortex position is NE of the 1700 track. Maybe only a quarter toa third mile, but on the proper side of the line, all the same.
I wish I hadn't lost the link to that Vortex archive over on Texas A&M's site. That would give us a better idea on whether that's a solid NE of the track or right on track.
