I know we've had some snowstorms in the last few days of October. I remember going Trick-or-Treating in 4-5 inches of snow (my family has the pictures to prove it), so it can happen this early in the season. I think I was Kermit the Frog that year for Halloween.
I don't know about you, but I'm not really ready for snow and bitter cold. It would be nice to just have 3 or 4 weeks of good fall weather (highs in the 60s and 70s, lows in the 40s). Enjoy the rest of your weekend.
