Wait until April?
I have had to dig my car out of snow and ice many, many times. I used to travel for work, and I'd often arrive home only to have to dig my car out of the airport parking lot after a foot of snow had fallen.
Get a good brush and ice scraper. I have one that is both combined. Brush off your windows, and remove ice with the scraper as necessary. Don't forget to remove snow from the car's hood, trunk, and roof - it poses a danger to drivers behind you if it flies off while you're driving, and it's illegal to drive around in a snow-covered car (at least here).
Get a portable snow shovel and keep it in your trunk. Also, get some sand or cat litter; you can sprinkle this on the ground for traction.
While I'm giving winter driving tips
be sure that your car is stocked with water and non-perishable food (nuts, candies, energy bars, etc.) in case you are stranded for several hours. Carry a blanket and/or some warm clothing (sweatshirts etc). Also, be sure your cell phone is fully charged so you can call for help.
