So what's the likelihood of counting down to 0 from 13 days out? 😂 

The previous run was colder sooner than the pub run.... 

Shhh it’s gonna count down smoothly 😁. I’m just grateful to be seeing some stonking output .

Slim at best tbh. Models are not consistent at all atm and any cold is already getting pushed back. If it all firms up over next few days then great but I for one won’t be getting burned again by this particular rollercoaster

Now that was a sneaky but cold easterly popping up in FI, didn't see that coming looking at the evolution beforehand!

There is some similarity between GFS 18z and EC det by day 9/10 this evening.

I was thinking PM shots but perhaps the momentum is moving towards a Scandy high?

Seems like another part of the puzzle unfolding on the gfs   now an easterly, where will this all end. Hang on gang we could be digging ourselves out soon .very interesting synoptics for us coldies, over to tomorrow for the Ecm .

Aye, leaves the Lake District I the Lee of the rain/ snow shadow like the BFTE did in 2018! Can we just have a potent northerly instead please?

Hope your right but I think the digging out bit may be a little to early to say lol, it will probably all be different in the morning, if it’s still looking like this come this time tomorrow and most other models have similar then maybe something to watch

Scandi block unlikely > Greenland block is more probable relating to the phasing of the 2 High pressures ( UK + Canadian ) Ie retrograde NW.

Shades of 15/12/2010!

 

Quite an incredible turnaround if it happens.

I eluded to that a few nights ago Steve, though given the way this winter has gone I think we would take either form of blocking 😂  Certainly signs that the main section of tpv will be going toward the Siberian / Scandinavian side.

Note the 'super high' over GH > I wrote about these in the winter forecast 18/19

Might be some signs of the PV weakening which may allow a ridge more towards Greenland but too me it's very tentitive and as far as the UK is concerned, the outlook has not changed to what we seen from most of this winter so far. If anything, quite mild air is once again is looking likely on some runs. 

Certainly nothing overly cold in the outputs showing I'm afraid.

The ECM clusters at T240:

It is interesting to compare the clusters at the same time from the day before's ECM 12z ens, T264:

image.thumb.jpg.23566d4f5f777fcdac50e1e2f8d51b2d.jpg

The signal for ridging to the NW seems pretty much new today, maybe the sixth cluster edging that way yesterday.  Will be interesting to see if these promising developments strengthen or disappear on today's runs.

Not really seeing a change in pattern to cold in the last half of January for the UK?

Looking at the D10 ECM means:

EDH0-240.thumb.gif.91f3052a99d083714a3f08ae7c680453.gif887092336_EDH1-240(1).thumb.gif.7d854315305e0e1ad29db42e16ea6c29.gif

That takes us to the last week or so of January and average uppers at best! The GEFS offers similar:

gensnh-21-0-240.thumb.png.5d8134987fda5a5fd8428ebb29855853.pnggensnh-21-1-252.thumb.png.823a443abbf0da5a468e96a12dd9b5ab.png

So neither suggests a change. Looking at the D16 mean on the GEFS:

gensnh-21-1-384.thumb.png.056cf8c029abed5132b1c8fc7378e5ff.png With current: gensnh-21-1-0.thumb.png.5aa961b49106a2c61987911fbbb88fda.png

...and we have gone full circle, tPV draining to Siberia and then returning across the Arctic fields back to NE Canada. In such a scenario we would expect a temporary lull in heights to the NW as this cycle completes. Maybe we can get a topple out of it, or a wedge of heights leaking north; but this to me, on what I can see, is the same-old same-old in a repeating zonal pattern with the odd interlude of a mini-ridge? Anyways we will see...

 I have to agree with your post I don’t think we are in for a pattern change yet yes some of the models are showing cold patterns I am not convinced yet also if you look at the Met office extended outlook day not going for a pattern change either how ever I will say this it is good to be called run appearing in models it is better viewing than what it has been over the last few weeks.  ☺️ ✌️

Well the 00z continues with the theme of HP Spreading towards Greenland and bring down some Cold uppers . although it starts to collapse it right at the end ... but lt's a start and would tie in with the MJO forecasts ...

Ecm 0z for the 20th last 3 days. Good consistency I would say. I’ve chosen this date as this is when changes may happen to nh profile.

That’s worth a little boom, A big one If it wasn’t at day 10.
