I don't think you have a shot with a 148. I think you need to get that to at least a 155 or so, even with URM status. I could be wrong, but they are an LSAT-heavy school, and you're applying very late.
I'm with Kalvano, sorry. I think a 148 twice is a little too low, especially for FT. I know a couple (read: exactly 2) people who got in last year with scores in the low- to mid-150s, but no one in the 140s. Even with the URM bump, it's unlikely. You would have had a better shot applying in October or November. Is there anyway you can retake and apply next cycle?
Also, the 3.91 is great, but your grad GPA doesn't (or only BARELY) counts when compared to your UG GPA.
