Don't lose hope yet. I got in there with a 158 and 3.94 gpa and I'm not even a UW undergrad. They are definitely looking beyond the numbers and I'm proof of that. I think they look favorably on people who really make it clear they want to go there, so I think you're in good shape. After all, you're not even outside of their official range on the LSAT and LSN is systematically biased by self-selection.
