Fair enough. So let's analyze why sufficient cold air has not been available. First suspect is of course the NPAC vortex. But as PSU has pointed out, that vortex has been present in past analogs that have been "cold enough". What's different now? Well the elephant in the room is the warmer base state of course, which can explain a lot. But gosh darn it, its not like there hasn't been any cold anomalies in the NH. It's just all been stuck in Eurasia. So that is what I want to understand? WHY has it been stuck in Eurasia?
