Try to keep your hand behind the ball during the armswing and until the ball comes off of your finger. Only thereafter you can twist your wrist and propel the ball with a lift of your fingers outward onto the lane.
A good idea is to imagine coming "through" the ball with your ring finger upon the release, and continue this motion fluently in your follow-up while the ball gets down the lane.
Additionally, try to rotate the thumb of your bowling hand as far out as possible - to the point it becomes a bit uncomfortable, and try to maintain this position throughout your swing. Feels wacky, but for me this worked quite good.
I am also a high track player and have the problem of rotating the ball inwards upon my downswing too eraly - killing the ball's power and releasing it inproperly. Changing my release as mentioned above and reducing pendulum speed to natural gravity has helped me, too, because I can let the ball do the work for me.
