Here you don't have to worry so much about the snow, but the ice that freezes under the snow. And when it does snow, all it depends is the tire. If you have an AWD car with the wrong tires, it's not going to help any at all. It all comes down to the tires.
My friend has snow tires on his AWD car's, and even he says without the proper tires he wouldn't be able to drive. So if you have snow tires on a RWD car, with enough weight in the back, you'll be fine in the snow/ice.
