I'd like to chime in with my experience of having lived in both the South (Tennessee/Georgia) and North (Minnesota).
The most important thing to do in your situation is invest in a set of winter wiper blades. Every parts store in snowy states will carry them. Winter wipers are designed with a stiffer rubber blade and a plastic or rubber wrapping around the wiper arm that prevents ice from building up and freezing the wiper onto the windshield.
Even if you somehow avoid cracking the glass, the water build up on regular wiper blades will turn to ice almost instantly. An iced wiper will end up either ripping the blade out of the arm and gouging a stripe across your windshield, or burning out your wiper motor since modern wiper motors won't shut off until they complete at least one full sweep.
Secondly, switch to a cold weather wiper fluid (-20F or lower) as soon as the first snow falls. Like centerfield9 said:
Spray some of the winter (-20F) windshield wiper fluid on your windshield and let it soak for a few minutes. This will get the ice off.
Finally, the only way to completely avoid having to scrape ice is to never park outside of a heated garage. Since this is virtually impossible, find a scraper with a good blade and a nylon brush for clearing off the top layer of snow.
