It was brutally cold for the entire last week of December. Literally as cold as it can get, for days on end. The short December days don't cause cold days in December - they cause the cold days of January-March. It's called seasonal temperature lag. And it's Meteorology 101. We just went through a sunspot cycle. It cycled towards warmth. Now it's going to cycle back towards cold weather. If you think that the average temperature between extremes is the "normal" temperature you're living in a fantasy world. That was a cold December. And for many of us, it snowed over and over again. I stopped counting a couple weeks ago when we hit 12 days with snowfall here in north-central Indiana. It's probably more like 15-16 now. And winter is, at a maximum, only 1/3 of the way through. Chill out.
