It sounds like the leak is coming from the windshield gasket itself. You might be able to add some sealant between the glass and the gasket on the outside. It could also be getting under the gasket at the top between the sheet metal and gasket and running down to where you're seeing it.

The ultimate fix would likely be removing the windshield and replacing the gasket with new sealant.
