1/17/2024 0 Comments Alberta clipperA fresh area of low pressure forms as the energy passes over the Rockies and moves into the Prairies. Typically, high pressure is in place along the Pacific Coast, forcing the atmospheric energy to speed northward along the jet stream into Canada. Several ingredients are needed for an Alberta Clipper to form. This then forms into a new storm system that sets out on a path southeastward into the northern U.S. However, the energy in them isn't lost, it keeps moving along. The rest of the name comes from where they generally form, Alberta, Canada.Īreas of low pressure moving from Alaska and the Pacific Northwest tend to fall apart as they cross the northern Rockies, unable to strengthen in the dry air of the Canadian Prairies. So, where do they come from? The name, "Alberta Clipper," comes from the fact that the storm quickly clips across the northern tier of the U.S., similar to how fast 19th-century sailing ships known as "clippers" sped across the seas. However, they do bring cold, Canadian air that can drop the temperature by 30-degrees or more. Since they form well away from a body of water, Alberta Clippers tend to not have much moisture associated with them, so they are not big snow producers. It's a winter storm system that usually starts just north of Montana, in the Canadian province of Alberta.Īlberta Clippers typically form just east of the Canadian Rocky Mountains. No, it's also not a hockey team from Canada, but you'd be close. It's not one of your father's power tools either. And when the systems are spawned in Manitoba, they are sometimes referred to as "Manitoba Maulers.Alberta Clipper is a funny sounding name. WHAT IS A SASKATCHEWAN SCREAMER: Weather system is force behind fierce winter stormĪ "Saskatchewan screamer" system is the same pattern as the Alberta clipper, but it is born in Saskatchewan, a Canadian province east of Alberta. Generally, the main weather features associated with Alberta clippers are some light snow and a reinforcement of cold air over the USA. The storms that rapidly intensify sometimes spread heavy snow over New England and southeastern Canada. However, if conditions are favorable, some Alberta clippers can rapidly intensify off the East Coast once the storm taps the relatively warm moist air over the Atlantic Ocean. WHAT IS THUNDERSNOW? Yes, you can hear thunder in the winter. Clippers typically produce only light snow because they're what meteorologists call "moisture-starved." Once an Alberta clipper forms, it usually moves rapidly to the southeast across the USA's Northern Plains and then to the east off the mid-Atlantic coast.Ĭities such as Minneapolis, Chicago, Pittsburgh and Washington are often the biggest cities to see this type of storm, according to the Vane, Gawker's weather website.Ĭlippers usually cause only light precipitation very few produce major snowstorms. WHAT IS A NOR'EASTER? Storms can batter East Coast with snow, impact millions of people Just like these boats, clippers move quickly. These storms get their name from 19th-century ships, which were known as clippers. The clippers develop east of the Rockies because air flowing eastward over the mountains creates favorable conditions for their formation. But what are they?Īn Alberta clipper is an area of low pressure that generally forms over the province of Alberta, Canada, east of the Rocky Mountains. in the middle of winter, you might hear forecasters talking about Alberta clippers. During major cold outbreaks over the U.S.
