Whats The Weather Like Up North?

I agree with what David has said. It's only recently [15 yrs?] that 'Lake Effect Snow' has been identified with the jet stream. The jet stream travels West to East, roughly from the Pacific, along the US-Canadian border until it hits the first of the Great Lakes, Lake Superior., where it makes a 90º turn South to the bottom of Lake Michigan. Then it turns 90º East to the bottom end of Lake Erie. Now it makes a 90º turn North to the border again, and finally turns 90º East again to the Atlantic. Whenever the cold air dragged along by the jet stream travels over a warmer lake it picks up the moisture and carries it along until it hits a colder landmass. Lake Effect Snow is the result.

The jet stream is a constant, and stays in the same position in relation to the Sun year round. It is only the axial tilt of the Earth that makes it seem to travel North in the Summer and South to the US in the Winter.

The Japanese actually launched 'balloon bombs' during WW II that rose to 32,000 feet and were carried by the jet stream to the continental US and Canada. Very interesting story on the History Channel on these balloon bombs.

Now, we get bombed with snow.

The History Channel/Discovery/PBS Home Video special is called "On A Wind And A Prayer" and is available on DVD.
