Currently, the Jet Stream is pushing from the NE and down over the Midwest. This results in the Midwest being within the trough of the Jet Stream. This event can be considered the Alberta Clipper. An Alberta Clipper occurs when a system of cold weather comes down through the jet stream bringing heavy snow. Appropriately named because the winter weather is coming from Alberta, Canada.
