Winter has come!

Winter has come! Last week was so beautiful---mild weather, sunny days, temperatures in the high 60s with no noticeable humidity. But since yesterday the sky has been gray, making the leafless tree branches look stark. And last night lightening lit up the darkness. Happily (for me) there was more lightening than thunder.
More of the same for today. Yes, I think winter is upon us in Chicagoland.
