Yes, this is the first snow of the season.
I notice little itty bitty flecks of snow in the air when I dropped *Z* off at the sitter's house this morning, on my way to work, and the flakes just kept getting bigger most of the day. As you can see in the photo above, by early evening there really wasn't any accumulation on the ground but the trees on the hills were getting some accumulation.
By nightfall it had started sticking to the grass (as you can see in the photos above).
