And yet on the other side of the Atlantic the warming Arctic seems to lead to a weaker jet stream that always seems to loop south and allow intense cold outbreaks way down to the Gulf of Mexico. The USA has seen countless cold records broken in recent years (which is partly why there is such a high level of AGW scepticism over there. It mainly seems to be Europe that gets the warmth.

Most of GEFS goes against the OP run so all is not lost for getting cold in

Teleconnections, mountain torque, PFJ, SSW, AO, AAM, NAO, MJO, LGBTQ+ WTF and seasonal Indicators? There's more indicators on a BMW driver.

None of it adds up in the new warming era.

The teleconnections (experts ?) are still screaming it is going to be cold, but are realising that screaming it is going to turn cold doesn't actually make the weather turn cold.

They are probably in a corner somewhere wondering why a mixture of AAM,MJO and MT mixed with IOD doesn't make wheatabix with warm milk.

I think index's such as Nino and mjo etc, have some small validity for north America etc, but there is simply too much chaos going on on this side of the pond.

Mon 12 Feb - Thu 7 Mar
Monday 12 Feb - Wednesday 21 Feb
Cloudy with showers or longer spells of rain across northern areas at first, with drier conditions in the south. Becoming mainly dry by the middle of next week, especially in the east, whereas western areas may see some rain or showers spread in from the Atlantic at times. Temperatures will probably be around normal, although colder conditions could develop in the east with overnight frost. Into weekend and following week, much of the UK will lie under the influence of predominantly dry conditions thanks to high pressure extending from mainland Europe, albeit with temperatures turning colder. However, milder, wetter weather from the Atlantic will always lie close by, with this encroaching from the west at times.

Whilst there is a large degree of uncertainty, conditions are most likely to be drier and more settled than usual through the remainder of February with winds from the east or north. This increases the chance of cold conditions and fog, with some wintry showers also possible. Early March may see a return to more changeable conditions with an increasing chance of weather systems moving in from the Atlantic.

I see you were talking about the 2nd paragraph Rob. It was the 1st paragraph that has dropped all hints of meaningful winter. 

As for the models . Pointless easterly drift on the GFS.

Improvement on the 6z op and might even slowly trend better in future runs but looks like sinking this one and not bringing in any cold.

I haven't a clue what the gfs has been up to  the last two or three days with their strat outputs but if todays 12z run is anything near correct then another beast from the east would be well within the realms of possibilities going forward. I have been patiently waiting for the strat runs to get back on track in regard to what they were showing a few days ago and in the last few runs they have been slowly  backtracking with todays 12z showing a peach of a run. A very large split from the top down with one part of the vortices over central Canada and the other over northern Europe with strong geopotential height straight up from the north Atlantic across the pole to the Pacific. 
Obviously we need to see this profile sustain but if it does then with a coupled trop/strat we could see a very quick trop response. For the next few days its a watch and wait brief but if this is the correct direction of travel then some extremely juicy charts should soon be coming into view.

Having said that I’m quite happy to have lower heating costs.
