Lake effect is when cold air moves across the lake and creates heavy amounts of snow. The recent arctic cold thingy started from the pacific ocean, came up into canada, and got caught in a jet stream Edit: Clipper and cold fronts
I found the article about it on wikipediaProfessor said:I'll take your word for it.I did not know that. I figured it moved in from the north-west as it usually does, so I guess that makes sense.
A clipper originates when warm, moist winds from the Pacific Ocean come into contact with the mountains in the provinces ofBritish Columbia and then Alberta. The air travels down the lee side of the mountains, often forming a chinook in Alberta, then develops into a storm over the Canadian prairies when it becomes entangled with the cold air mass that normally occupies the region in winter. The storm then slides southward and gets caught up in the jet stream, sending the storm barreling into central and eastern areas of North America.
The storms sweep in at high speed over whatever land they encounter, usually bringing with them sharp cold fronts and drastically lower temperatures. It is not uncommon for an Alberta clipper to cause temperatures to drop by 16 °C (30 °F) in as little as 10 to 12 hours. Often, the storms bring biting winds with them, only increasing the effect of the lower temperatures. Winds in advance of and during an Alberta clipper are frequently as high as 56 to 72 km/h (35 to 45 mph). These conditions would cause wind chill values to drop into the -30 to -45 Celsius (-20 to -50 Fahrenheit) range. And one-three inches of snow
