my car and weather predictions

Yesterday, I took my car in to get my snow tires on. I also got an oil change, and ended up having to do the back brakes too. But, it was the snow tires that I needed. I took a look at the long range forecast recently, and was shocked to see this...

I don't want to be in that rush of people on Dec 8th all trying to get their snow tires on all at the same time. And even though there is no guarantees that it will snow then, I would still rather be prepared now.
