Windshield Fogs up

Cool air fogs the windshield on the exterior surface. And the windshield fogs when I turn my defroster on. I was on the freeway it started raining and I turned on defrost and windshield instantly fogged over. And there are opaque white spots with the fog. Where should I look for the problem? Any ideas?
