OKAY weather watchers, this article is in enormous detail.
Any feedback would be appreciated.

Tiny excerpt:

So why is all this important? Why do we care about the Polar Vortex every Winter?

The answer is actually quite simple. This stratospheric polar circulation, called the Polar Vortex, can mean the difference between a very cold and snowy winter and a Warm and dry Winter.

A strong Polar Vortex usually means strong polar circulation. This usually locks the colder air into the Polar regions, creating milder conditions for most of the United States and Europe. In these conditions, the Winter can be mostly warmer than normal across the mid-latitudes.

In contrast, a weak Polar Vortex can create a weak jet stream pattern. The colder arctic air is harder to contain, which can now escape from the polar regions into the United States and/or Europe. Image by NOAA.

1. 2014 saw three cold blasts into the Continental U. S.

The first blast was the worst. Here in my part of Western PA, the temperature dipped to -17 degrees F. The extreme cold was caused by a weakened poler vortex in early 2014.
