Polar Express?

You can see the polar vortex, the circular air flow north and west of the Great Lakes. This is supposed to bring very cold air to the football game in Green Bay today. But they're not unused to that kind of thing there.

A long time ago I experienced something like this, and wrote about it on this blog post here.



This wouldn't be that cold if it made it all the way to Maine. But it is an interesting weather phenomenon, a good warm-up for Global Change.
