I just got back from picking the Expy. No more wind noise!
It was coming from the front wiper cowl not being all the way seated on the drivers side. I guess it was misdirecting air somehow making it sound like a window was partly down. The dealer said the clip had to be replaced (which they did) and now the cowl is laying flat like it is supposed to be.
I am not able to post an attachment but I put a couple of pictures of what it looked like before they fixed it in my gallery. Below are the links.
