00:00What is an Alberta Clipper?

00:01We've been talking about it a lot.

00:04We're currently watching one now.

00:06What does it mean?

00:07Well, this is the general

00:09path of an Alberta Clipper.

00:10It really rides this Southeasterly

00:12flow of the jet and generally

00:14produces snow anywhere across

00:16the Northern Rockies and Northern

00:18Plains all the way across the

00:20Great Lakes in it to the Northeast,

00:22bringing that cold air with it.

00:24But you know it meets up often with

00:27this milder air out ahead of you.

00:29It still that helps fuel some of these

00:32snow storms characteristically of

00:34these Alberta Clippers now I love

00:36to dive deeper into these sneaky

00:38little storms where they originate.

00:40We have to look at their origins right

00:43to see why they do what they do.

00:46This storm moving fast because

00:48it's coming from central Canada.

00:50Typically an Alberta Clipper does

00:52come across the province Alberta

00:54or originates there and it's

00:56coming from the North.

00:58Alberta or originates there,

00:59but it's fast moving because it doesn't

01:01have a lot of moisture to help fuel it.

01:04So it's going and it's trying to

01:06drive as much energy across this

01:08zone as possible and get as far as it can.

01:11That's a big factor when it comes

01:13to Alberta Clippers and why they

01:15don't generally produce high,

01:17high amounts of snow,

01:18though in some cases,

01:19especially when we talk about

01:21Lake Enhanced Snow from Alberta

01:22Clippers like we're seeing even now,

01:24we could see isolated areas where

01:26we could see isolated areas with more snow.

01:29They are fast moving.

01:30They typically originate from

01:31the Canadian province, Alberta.

01:33They are most common in late fall

01:35in winter as it is very dry in that area.

01:38They often produce gusty winds,

01:40and in this case,

01:42if an Alberta Clipper or the energy

01:44from it slides into the shore,

01:47it could of course also move north.
