Well, looks like the slightly faster low pressure arrival forecasted for the past few days by the NWS in Philly, in particular (vs. the NWS in NYC and many other sources) will verify. That 3-6 hour difference will make the difference between a completely dry game and what looks to be a moderately wet one. Kudos to the NWS in Philly.
Anyway, tailgates should still be mostly dry to dry, with, at most, a very light shower or two before gametime, although it will be getting cloudy by about noon, with temps reaching highs near 80F during the tailgates. However, chances of rain will be on the increase throughout the game and a stray t-shower is possible, especially by the 2nd half. Rainfall amounts should still be on the light side for the game, i.e., 0.1-0.2" and with temps in the mid-70s, it won't feel too bad for most. If rain makes you melt, bring a poncho.
I will say this. We arrived in OC NJ yesterday for a week vacation and the view of the sunrise over the ocean from our beachfront rental (amazing how much cheaper rentals are after Labor Day) is breathtaking. Bikers and joggers are out in force already and it being OC, it's not much to look at, lol. Paging newell138, lol. The only downside of a family reunion in OC today is that I'm going to miss the game, which sucks - relegated to TV watching.
