Need some match help on this cut

[sierra mist]

My table saw only goes to 30 inches and I need my boards cut down to 32 1/2". I ripped it down with my circular saw and then I got precise with my table saw. I have 5 boards left at 49 1/8" ( it was sold as a 4x8 sheet). I want to use my table saw to cut them down to 32 1/2". I figure that I can just set my table saw to cut 16 10/16. The kerf is the blade is 0.98". Shoot, I don't know how to convert this into something I can use to adjust for the thickness of the blade. Can anyone help or offer advise? Maybe I'm going about it wrong.
