I've been looking at the weather models and over the next week, it looks like this arctic outbreak might intensify and even colder weather will plunge into the upper midwest into the mid south. The jest stream is solidly locked into an omega block with a huge ridge of high pressure over the west coast and a large Hudson Bay upper low over.............the Hudson Bay. That in turn means the jest stream goes from northwest Canada towards the upper midwest USA and smaller scale storm systems just keep pulling the arctic air near the north pole down south as they ride the jest stream.
