Yup. The net outcome, as UKMO explain well, is how major anticylonic flow by Fri across NE Russia leads to a shift of stratospheric polar vortex position to the SSE, resulting in a marked reconfiguration in the N hemispheric pattern.

Interesting tweet from Fergie for those who like their cold weather.

Yes, plus models will struggle to capture how/when this all gets popped by mobility returning (which may be a rather torturous sequential affair, rather than all in one go). Either way, the risk is evident for most widespread cold conditions thus-far in winter 17-18.

John Hammond on Twitter seems to be informing people that met office will update regarding cold potential soon.

No, quite underwhelming with a quick cols snap then back to unsettled Atlantic kind of flow with occasional cold snaps....very non- commital

They mention cold then the jet firing up and blasting the block out of the way with a potential snow event. Obviously now it's looking more likely that the cold continental feed is looking more likely.

According to a meteorologist from the met that was on this morning, just before the guy who uses traditional methods, next week is going to be cold. Sounds good to me. Let's see if that is what the new update is.

They don’t mention the jet at all ?

im talking about the forecast to jan 16th

you can read it how you want to (as is usually the case). Doesn’t indicate the milder conditions will make it across to the eastern side by mid month.

Are we talking about the BBC's thoughts or MOs? As I was talking about the BBCs and I'm not trying to read how I want to.

Oh right - I mean the mo. And ‘reading how you want to’ isn’t a criticism of you or anyone. It’s just how it is. We can all interpret stuff in different ways.

If that is right and obviousily a long way out then that shows quite a posiive height anomoly over Greeland.Not a bad thing for the UK?

With low pressure to the east you would have to fear for the sanity of so many. Although on reflection it's probably already too late for that.

Rather depends what you mean by cold but within my limited understanding I don't know of any direct correlation with pressure distribution in north west Europe. It does seem to be related to the pattern change in N.America but downstream still looks pretty unsettled with trough domination into the ext period according to tonight's EPS mean anomalies.
