How does the Audi A5 handle in various weather conditions?

I am looking into purchasing an Audi A5, but I live in an area with varied weather. Will this car be able to handle snow and rain effectively?

The Audi A5 is equipped with Audi's legendary Quattro all-wheel drive system which provides excellent grip and traction in snowy and wet conditions.

I've driven my Audi A5 in heavy rain and it handles like a dream. The brakes are responsive and the car feels very stable on wet roads.
