Winter is Coming... Series- What is a clipper snowfall system? Q/A

Average Clipper Track
Q: What is a 'clipper'?
A: Called an Alberta Clipper in its formal name, the clipper is a snowfall system that drops from Alberta, Canada and affects the Upper Midwest. It is a fast-moving low pressure system that can bring much colder temperatures behind its passage. Due to the fast movement, snowfall amounts are typically low, but have been known to go above 6 inches.

Q: How much snowfall can typically be expected from a clipper?
A: Usually 1-3 inches of snow due to the moisture-starved nature and fast movement of the storm. A stronger clipper can put down 6 inches or more, but that is more infrequent.

Q: How much can temperatures plummet after the passage of a clipper?
A: It is typical for temperatures to freefall 30 degrees right after the passage, accompanied by nasty winds.
