Right now we're in the middle of Fall, and the ground is totally covered in snow!

Don't get me wrong, I love the snow, but I wouldn't expect the snow to really start showing up until the last few days of Fall at the earliest! As it is, it looks like we are in the middle of Winter, but we still have a week of Fall left!
It seemed like we were really getting into Autumn during mid Summer too, so, I expect we'll see the snow start melting at the beginning of Winter!
I love the seasons, I'm just curious if this is a bug or if maybe I am not understanding what's going on with them~
