I don't even know where to post this. According to GFS at 8 days, Alaska is going to get a taste of southern Texas weather around April 1.
looks to me like the polar cell gets distorted into a figure 8 shape, both cores trying to fly counterclockwise. then the arctic gets a blast of warm air. while we're dealing with wild weather, the polar cell consolidates into a circular shape. the whole thing rotates counterclockwise for about a week and then begins to lobe as the perimeter lengthens. then the cold rattles around all that loose perimeter until the polar cell splits, the arctic gets a blast of warm air, and then the whole thing twangs back together again. the cycle repeats but now it's 4 - 5 times per year.
