It doesn't tell me too much really. One point on a chart isn't really a trend. I love how these guys come out citing snow storms as somehow significant. It's as if they don't know the difference between "wet" and "cold".
It's chilly up here in Connecticut too. That's normal. Next week it's supposed to warm up a bit. Of course it hit 70 in the first week of December... That's different. Go figure though.
