Here in the D.C. area now, it's downright cold. We always manage to get a strong blast of Arctic air right around the point-in-time which the calender flips into November (Mother Nature sure has a thing for dates). At my location we're already right around freezing, and I honestly believe we'll hit the 20's tonight. There was a Wind Chill advisory regarding low temperatures as well, with the WC factor expected to run into the mid-to-lower 20's Sunday. I'm loving it to be honest, because it's the first taste of Winter (It's not unusual for us to get some snow flakes by Thanksgiving)! It'll moderate somewhat by the end of the week, but I'm appreciating the crisp, clear air
Oh yeah, FYI this pattern is so far following right along our normal seasonal climate fluctuation. Sometimes the colder November is, the warmer January will be, but it really depends upon quite a bit.
