Leaking when it rains? Where in the hell is this water coming from?

Well, If you run water into the cowl vents (in front of the windshield) and it leaks into the car then it could be the vent duct risers inside the cowl??
If you run water around your windshield seal and you get water into the car then it could be the seal??

Besides the w/w seal there aren't too many other ways for water to get into the car in front??
