This is where a time series for similar dates would be useful. However, I scrolled back to early December and the same energetic discrepancies prevail. The dual Arctic counter clockwise and clockwise vortexes at 10 Hpa rotate eastward with the 'high' breaking down over water (Dec 25 thin covering most of Atlantic). By Dec. 31, the 'low' is centered on the pole and the high is dissipating over N Africa with a new high staring up over the Pacific. By Dec. 5 this high elongates to cover all of Asia. By Jan. 11, there are two highs, the Pacific one has drifted westward while a new one emerges over Florida, while the 'low' rotates toward N America. By the 16th, the Atlantic 'low' has strengthened and is located over ~Shannon. The cell setup is now opposite that of early Dec. Could this be a signature of energy exiting opposite the sun? As for the 'high's' location over Shannon, all I can figure is that St. Patrick is returning the snakes to Ireland.

The torque the infinity sign over the N.Hemisphere places into the Strat , at all heights, might give us a better handle on the forcings that , this time last year, drove Ozone holes over the Uk, a record early final warming over the Arctic and the refusal of the QBO to change easterly ( as it ought to have).
The Arctic winter , so far, has been far worse than the one that saw those events so what will it drive this time around?
The forecast SSW , at months end, might be a signal that we are to expect more Strat oddness..... a month earlier than last year.

Not sure what you mean GW....as this graph shows SSW can occur from december to March. ...??

It does acidohm, but let's let Graywolf pretend to be in misery.

So I tried past periods, I assume you saw that data is accessible back to 2014 but some missing days interferes with the loop That low pressure is maybe doing what other potential cold outlooks have done this winter so far and been 'over modeled' if you like, at least for UK. ...

Thanks Acid, I've been looking at that.

Winter's with us to our dismay. It's getting colder day by day. Long underwear or our elders freeze, And brass monkeys calling "Welders please." No applause, please.
