Ripping a bunch of boards; they bow away from the saw, now what?

I have about forty 15/16" thick soft maple boards that are about 6 feet long. I need to rip them into 1 1/2" wide strips. They have been rough planed to this thickness and that finish is good enough for the job at hand.In my humble experience, they seem to be pretty nice boards. Most of them are pretty straight.The edges are rough off the sawmill.So--- I jointed one edge to make them dead flat. Now I take them to the table saw. It's a pretty new Delta hybrid saw with a nice sharp carbide blade. When I rip the board, the 1 1/2 inch strip that I am cutting is closest to the fence. About 1/3rd of the time the slat bows away from the blade, pushing the still uncut part of the board away from the fence a little bit, let's say as much as 1/8". This, of course, keeps the slats from having a consistent width. The slats that did this, when the cut is complete, are, indeed, warped. But, if I wait an hour or so, most of the warp is gone from the slats.What can I do to prevent this bowing away from the blade?Pete Stanaitis----------------
