What's an Alberta Clipper?

Alberta Clippers are dominating our Madison, WI weather, and will through the week. We've got one on the way tomorrow and one following that on Friday. So what's an Alberta Clipper? A new hockey team from Edmonton?

It's a low pressure system that originates in Western Canada and brings snow, high winds, and unseasonably cold weather to the Great Lakes region. These are not the systems that bring the most accumulation of snow to our region, but they can bring up to 6 inches, just enough to make driving challenging. Once it passes over the Great Lakes, it can produce lake effect snow and if it goes into the Atlantic Ocean, an Alberta Clipper can become a Nor'easter. And I believe, if I am not mistaken, that Alberta Clippers travel along the Jet Stream.

I wonder how much snow we'll get tomorrow. I'm hearing 3-5 inches on the Weather Channel.

We got about 4-6 inches. It was still hard to drive, even though the roads were being cleaned. Just had to concentrate very much and that makes me tense and tired once I get where I need to get.

I think we got between 2.5-3 where I live. I just try to go slow and try to remember that it takes a lot longer to slow down on snow/ice than it does on clean pavement. There's a winter driving school in Michigan, and I'm seriously considering taking it so that I can be a more confident winter driver.
