Lots of rain and fairly heavy wind gusts. Around 3:30am I heard a loud thump outside; a quick survey of the inside of the house showed no leaks.
When I left at 4:30, the rain still coming down in buckets, I was greeted by this in the driveway
Right dab schmack in the center of the rear window on the Passat.
Hurray for duct tape and plastic garbage bags.
