Post Summer or Pre Fall

Today's weather was crisp but clear. Believe it or not, this morning we had our first snow flurries. Snowing on October 10....that has to be a first. The plants are valiantly trying to survive...the last of my smmer pink geraniums are blooming and yet the first of my fall sedums are too. So what time of year is this really...late summer or early fall? But then again...maybe winter? I'm so confused...
