Alberta Clipper

meteorology

1. :  a fast-moving low-pressure weather system that develops east of the Rocky Mountains in western Canada during winter months and moves to the east-southeast across central Canada and into the northern U.S. ◆An Alberta Clipper typically brings very cold temperatures, high winds, and light snowfall amounts. Expect another Alberta Clipper to move through southeastern Wisconsin this afternoon and tonight with about 1 to 2 inches of snow and then flurries on Saturday. — Brian Gotter
