Where is the Fall weather?

I think we jumped from Summer to Winter. It is so chilly here today. The low last night was in the 30's. I went out for lunch today and needed my North Face jacket. Burr. I could have used a scarf too. I think maybe with the wind it makes it feel colder than it really is. The air is still on in our building and I am freezing. So my question would be, where is the Fall weather?
