The Nationwide Series cars use rain tires and ran a session on the wet track, but the Cup series doesn't, and won't.
Updates on the session to follow, if it runs.
Update: The final practice session began late due to moisture still on the track. After 50 minutes, Brad Keselowski had posted the fastest lap.
Update: Kurt Busch finished with the fastest lap in the rain shortened session (61 minutes).
