By way of an example of how, er, fluffed up the atmosphere is at present we have a monster depression forming in the North Pacific at a latitude similar to ours. All part of the current strong blocking due to La Nina and NH SSW I suspect.

Re: Wonky weather
Yes, lots going on. The Siberian high in the 1080's hPa, bomb cyclone and a major SSW underway for the NH as you mentioned. The infamous twin sister vortex is appearing in 5 days from now on most models. EC going for a complete polar vortex displacement towards the UK in 10 days. 60 to 70% of these events fully couple into the troposphere within 3 weeks and this has started already. One would assume this is a major cold wave brewing for parts of the NH towards the end of January.

Re: Wonky weather
GFS splits the northern hemispheric polar vortex in mid Jan. The cold wave in the troposphere is going to be epic if that verifies.
