Where has the fall/autumn gone?

It's too cold outside that i'm too lazy to go out. It snowed yesterday. The first snow this year. The weather is very strange. It wasn't too cold for the past few days and it suddenly snowed yesterday so now we are freezing here. When I woke up this morning, I saw the whole City in white. It's really surprising because most of the plants and trees are still green. I didn't experience fall season. Although it's cold at night but it's sunny and warm in the afternoon. And the surrounding is not too dirty because of the falling leaves. Unlike the past few years, it was too windy and cold from October.

The snow came earlier than last year. It's hard to say what kind of season we have here now. Is it fall or winter? Where has the fall/autumn gone?
