My first post about this remaining uncertain until close to gametime looks prescient. Still significant discrepancy among the NWS offices and other major weather outlets. NWS Philly still calling for 0.1-0.2" of rain during tailgating and the game (with more possible in t-storms), while the NWS in NYC is still only calling for <0.1" of rain before 8 pm for very nearby areas - can see it in the updated graphics above (which are "live"). Most other media outlets just calling for a slight chance of showers before Saturday evening.
NWS-NYC discussion makes a great point about the GFS being the outlier in bringing the precip in faster than the other models, i.e., during Saturday afternoon. Will be interesting to see how it goes. Personally, I'd be surprised to see much rain before 6 pm based on what I've seen so far, and even 0.1 or 0.2" of rain when it's 75-80F, shouldn't bother people too much. Since I'll be on vacation in OC for this game and since rain may actually help us against WSU (they certainly did poorly in the rain last week), maybe I'll root for rain, lol.
