Extremely Amplified Pattern Will Set the Stage for Arctic Cold

Good evening! The changes to the pattern have been discussed for a while, but now that the model data has finally caught on, things are starting to truly get interesting and we can entertain possibilities.

An initially very zonal pattern will quickly become very amplified thanks to changes with a train of waves in the Pacific and a traffic jam of waves building in the Atlantic. Eventually this forces an amplified ridge in the Pacific to build towards the Arctic and dislodge plenty of cold into the Eastern half of the US, as the corresponding deep trough will have nowhere to go thanks to the aforementioned traffic in the Atlantic.

The video below has all of the details on the coming cold, its severity, and potential duration. It also discusses potential winter storm threats that may arise in the pattern.

For discussion on just the cold risks, you can watch the first 12:50 and not bother with the rest of the video. The storm threat discussion starts at 12:51.
