Strictly for fun at 7 days out, but here's how weather site Tameteo present the ECM precipitation charts for Mon 2nd. Snow showers - shown in green - into Scotland and then down the NE coast before dying out overnight into Tues:

The ext EPS is not as quick to progress the pattern east as the GEFS, ergo the vortex trough extension into Europe and the Atlantic subtropical high are still quite influential  Thus the strong upper flow exiting a relatively amplified North America still has a north westerly component over the UK

Christ it must have been a good day of model viewing - nine pages to catch up on since I logged off this morning. 

That really is a lovely ECM tonight for all of us who enjoy some seasonal early Winter weather. 
Makes the build up to Christmas a bit more festive as well! 
Plenty of cold days, frosts and some snow for quite a few of us.

Now that’s the real deal!!! (For the time of year )

Lovely choice of gifs David. I tell you what if the ECM mean is anything to go buy.. He will most certainly be losing that tan come end of the month... First time I have witnessed that mean dip to around - 5 since the talk of cold esculated a few weeks ago. It does trend higher by day 10...but that's a long way off, and will be subject to change.... Enjoy the ride folks..... Next stop..... - 10 celsiusville....

While the models have indeed upgraded it's worth keeping in mind that heights over Greenland don't really persist beyond 24hours. So the outlook is a cold one with perhaps frost persisting though next Sunday/Monday. But widespread snow is not showing yet anyway.

Saying that it's been a different Autumn with temps rarely exceeding 10C over the last 3 weeks. So confidence is rightly high as we move into Winter proper!!

I don't think these types of setups are going to produce widespread snowfall anyway - that's not what anyone is really believing in. 

We are all for it turning colder with wintry showers and frosts.

Cant wait possible epic evolution in process. Solar minimum with climate change my bet.

Sydney getting some long awaited camo❄❤???????

That's if there is much precipitation with them synoptics which I suppose there would be. Sydney seems to be doing a lot lately from having sneak peaks at the met office models with his Christmas hat on to getting camo. ☺️

That's close On a Bartlett, don't wish to hard.

No - a bartlett is orientated such as to bring up winds from the South West, It is also a huge area of heights covering practically the whole of Continental Europe, there is a trough in Southern Europe on that chart.

So, big upgrade on the medium term insofar as the EC mean is concerned-

Confidence increasing of a 4 or 5 day colder and drier spell, would like UKMO to fall in line on the 00z runs to show something akin to EC det ..

Would be brill to have a cold frosty weekend with the markets and folk doing their christmas shopping.

Beats wind and rain and temps of 10,11 or 12 deg..

It's nice to see you posting charts in clusters Karl instead of a single column,makes for easy viewing for phone uses

loving these cold charts coming out,hopefully more to come,thanks.

The confidence 2/3 days ago was high re zonal/mild end of month into Dec, now confidence is high that this approaching cold shot will shift and turn mild again.  We’ll see......7/10 for me that cold will grip and come at us time and again this Dec......that’s my stance and has been for some time......let the battle commence

 

BFTP

Indeed its strange. 

It will be interesting to see where we go after the cold spell (if it materializes) 

Backgound signals showing a return to a more typical December but as each run toddles out the low solar activity may mean that the atlantic might not have as much energy as it may think.

That Azores high is strong, being backed East to join the high further East, the trough is in significant, winds will start coming in from a Sw direction as the vortex tightens , it's a Euro high close to being a Bartlett soon after at chart. 

All academic right in the depths of super fi territory but in the particular op run the Azores high is once again trying to extend towards Greenland its a cool/cold zonal setup and pv still favours more Siberia side than candian?

Winds coming from the Greenland southern tip peninsula.

The midweek low with the ecm. Interesting reverse movement south east which I'm taking as being down to the secondary energy flow around the high cell. Any thoughts @johnholmes

Just as the 18z fire up a reminder of where we want to see the under cutting developing

Also the ECM control goes deep cold out to day 15 !

Steve surely the icon cannot improve any further from.the 12z!!!the gfs 18z surely can improve a bit more with more amplification in the atlantic and more undercutting!!

Adding to that after looking at the jet and 300 mb flow, I cannot see why it should be positioned as far south as that. It must mean GFS/ECMWF/Met have a slightly differeint upper air pattern in the last 12-18 hours leading up to that time?

Yes that's more or less what I was thinking
