In the next week you will hear a lot about the terms “jet stream” and “polar vortex” if you have not already.  What are these phenomena?  A couple of easy to understand references you can use:

AthensGAWeather has a link to a website at the bottom of the page with a simple 2-minute explanation of the jet stream by Paul Knight, the State Climatologist of Pennsylvania here.

ABC News has a story about the polar vortex here.
