It's the Earth doing what it does. The jet stream over the US has shifted up through the West Coast and dipped way down into the South, that is why the Midwest is so cold. This has nothing to do with climate change or global warming.
On that note, this is how winters used to be and this is what winter is known for. Cold, snow, blizzards, a break in the cold for awhile, another storm, more snow and cold. It should be expected. It's been an easy ten years winter-wise, but now the Earth is fired back up. I've been around long enough to see this is a cycle.
I remember snow drifts up to the gutters of the house I lived in as a kid. I remember 20 and 30 foot piles of snow in the parking lot of my high school. I remember the winter of 1982-83 where we got very little snow and the temperature never went below 32 degrees. It wasn't that long ago we got a long, but almost snowless winter. A few years later, 2005-06, it snowed for awhile then rain the rest of the winter.
Last year and this year: "Global warming is the worst it's been / this is the fourth snowiest winter we've had in 100 years!"
