The two jet streams that directly affect our weather in the continental US are the polar jet and the subtropical jet. They are responsible for transporting the weather systems that affect us. The polar front is the boundary between the cold North Pole air and the warm equatorial air. jet stream is an area of strong winds ranging from 120-250 mph that can be thousands of miles long, a couple of hundred miles across and a few miles deep.
Though the cold it brings can factor into winter weather, for the most part the polar vortex is not in itself a weather maker, being quite high in the atmosphere. Winter weather is more shaped by the position of the jet stream, along which low pressure systems move. In practice, the northern jet stream is the boundary between cooler air from the north and warmer air from the south, though the jet stream is not as high in the atmosphere as the polar vortex.
