A punishing storm has much of the U.S. bracing for severe winter weather. So what is an Alberta Clipper? And what should those in its path be expecting?

Alberta Clippers are quick-moving areas of low pressure that originate in the western Canadian province of Alberta, usually tapping some energy from the polar jet stream and sometimes a bit from the Pacific. The name “clipper” was coined in the 1960s and derives from the fast-moving sailing ships of the 19th century.

As a fast-moving system is expected to bring some plowable snow to Vermont, Northern New York and much of New England this week, many might be wondering what an Alberta Clipper is. We break down what this term means and where it comes from.

A winter weather event known as an Alberta Clipper will descend from Canada later this week and roll across the northern tier, potentially bringing snow to at least 12 states from the Dakotas to New England.

Meteorologist Matt DiLoreto explains what an Alberta Clipper is and where the name originated. A relative of Vladimir Putin has accidentally let slip secret Kremlin data that reveals Russia’s losses in its war in Ukraine.
