What did the tracking say when it was in your city, and what did it say when it moved to San Jose? I might be able to figure it out. The USPS network is all kinds of fucked right now, the way they are consolidating it makes the mail move ass backwards sometimes. Like in my city they are phasing out a plant so mail lands at the airport and instead of getting sorted 2 miles away it goes 30 miles over to the new plant on the other side of town, then comes back to the old plant for the local sorting. It adds an extra day for no reason. Your package may be mixed in with other destinations that need to get separated at the main plant.
