In my experience, when a package is on the move usps can't pin down its exact location. Usps has the same information you have.
It's almost no way to tell since it's not the big company who specialize in delivering. If your package has a signature requirement and no one was available to receive it then it will be returned to the warehouse and you can go there to pick it up.
Probably not.
