The deep low pressure system in Alaska will be going down very soon. After this Sudden Stratospheric Warming event, the warming may begin to propagate downwards. Either way, we will be seeing this Alaskan Low erode as progressive storm systems crossing the Alaska will pull its energy away. That, combined with the persistent ridge in the far upper Northern Hemisphere, will work to get a ridge in place where the Alaskan low WOULD be. That ridge will provide building grounds for some serious winter storms.
