  1. Great model watching at the moment. Momentum products are generally neutral - but the key here is that the GWO hasn’t descended (yet) into a Niña style orbit, meaning the kind of forcing that would help produce a flat pattern isn’t in process. Instead the GWO is holding in a high enough orbit to suggest amplification will continue. Meanwhile we have rising mountain torque once again, predicted on the back of frictional torque that started to rise a week ago. Resultant pacific jet energy is very evident at the moment, not just for today but for the next 10 days or more if gfs i

  2. Why are you a member on this forum then, or even reading this mod thread, what do you hope to get out of it? Some really strange posts in here today, and the irony is they come out in greater number when things actually look interesting for once. Remember guys trop vortex all over place so blocking is more likely to feature than normal, big +EAMT which I don’t understand totally but this has kickstarted potential SSW and enhancing blocking as we move into late December / early January.

  3. If anybody wants to take advantage of this busier than average period we're experiencing at the moment, but trying to make a name for themselves by being contrary for the sake of it, or a little bit snappy or otherwise just trying to spoil what should be a nice harmonious discussion about the weather....good luck!

  4. A cold Christmas followed by a NH pattern promising a prolonged cold spell,what more could Winter lovers wish for? Yes signs now that a chunk of the vortex is going to transfer across our north towards Scandinavia in the mid-term as we see a second amplification upstream post Christmas. GEFS mean day 10 Both suites have the same idea just slight variations on the ridging,Obviously it would be good to see it drive as far north as possible to swing that cold to the ne more directly our way. I wouldn't be concerned with snow chances yet.Let's see this pattern firm up and

  5. Afternoon All- Im sure there will be some Euphoria from the 12Z GFS A couple of interesting points * Watch out for a shallow trough from the North on Christmas eve bringing Snow to Scotland. * If we do get this amazing jet profile at 168 the its Greenland high all the way... A GH profiled at just 7 days > Will need Euro support...

  9. Jeeze.. over the years I have pondered if you’re simply a glass half full chap or a troll. What we are seeing modelled at present and within the mid term are once in a decade Synoptics and the most hearting thing was that gfs and ecm were aligned at 192. we Might be taking different routes but the outcome is positive for coldies so with all that being said you’re not going to clutter and litter my enjoyment and knowledge gaining anymore. You’re number 5 to the block list...goodbye. 🙂

  10. Really? From the 27th until the 29th at least, - there are hard frosts predicted and daytime temps struggling to get above zero - 528 DAM line far south of the UK - Low pressure domination - 500hpa temps below -35c -850hpa temps below -5c -Dew points below 0c Thats all on "that" model run you "dissed" , to suggest theres nothing "significantly snow or cold" is not how those figures look to me! Now you are quite right of course, it is a long way off and may well turn out to be less wintry, but this is the model discussion forum so discussing what the current models show is

  11. I do understand some people's 'concern'. But I live my life very glass half full and have no intention of changing that any time soon, but each to their own I suppose. Better to have loved and lost and all that... There is a consistency here, an 'all routes lead to cold' feel about the current chart output that isn't usual at all. We may have to wait another 10 years+ to get this sort of potential again during a Xmas period, just enjoy the ride folks. It's not just bad luck that we struggle to see a white festive period, late December into January is a traditional period for mild wet and

  17. Evening all! Hope you are all well! Exciting times for a cold/snow lover! Lots of chat about late December/early January and rightly so! However - wee bit of naughty cold sneaking into the semi reliable timeframe of 120 hours/day five. UKMO 120: 13:00 UKV snapshots for 120: 15:00 Precipitation type & sea level pressure: 850HPA: Wet bulb freezing height (m) Dewpoint temperature (C) Thickness (dam) 23/12 to 25/12 at least has chilly days, risk of snowfall/wintry showers for some

  19. I was about to post something similar, so odd! Anyway, back to the models and another delicious GFS today and not the manky old 6z or pub run either. The Control also very much on the same page, now to 240 And yes, this is at day 10, but was set by day 7/8. Then there's the Strat profile for 29th December. If this doesn't get your weather juices racing, then really there's no pleasing you.

  20. Those of us around here long enough, will remember the winter of 09-10 where the models, nearly in unison, counted down the days from 12 days out with northern blocking, coming in with every run! This has the same sort of feel about it, consistent and all singing from the same hymn sheet. That said, we've been bitten before, at 96 hours out, but that happens mostly with Scandi highs. GHP's are that bit more reliable IMO. My advice would be, enjoy the eye candy charts, and if they come to pass, then super. If they don't, then so be it. This year has been horrible for hundreds of thousands

  24. Wow,have I missed something 😅 Firstly those 12z ens are pretty encouraging moving forward, and I'm aware the ECM earlier was a peach. I'm gonna bring you some positive news from Jon Hammonds updated blog this week.. Brief cold snap Xmas! Weather systems perhaps being blocked by colder air to the East..the jet carrying these systems having a tendancy to split rather than dive across us. There is a very real chance colder air lurking to the East will re assert itself,and this looks increasingly likely as we enter 2021.. Its been pointed out that many Long range Models were writing off

  26. Moved house today. Chaos. Popped in now for a quick look at various bits of data to see this GFS chart for Xmas day. Not much needs saying other than - Yee Haar! It’s still too far out to be served with clotted cream and a dollop of jam....but it’s a damned tasty looking setup for sure! All the key elements are there. Siberian High edging to the Urals....trough dropping into Eastern Europe, obvious open door up into Greenland, clear wave break eddy effect on the back of the next momentum spike producing a highly amplified pattern. And the Berlin charts have renewed wave 2 impact

  27. early evening observations a week is a long time in this place - go back to last Friday evening in here if you don't believe me! ICON is sometimes right when it is persistent against the other models - its the only model not positively tilted around greeny day 6. but at day 7.5 it looks like it would still go down the route of nw/se jet and diving trough finally, we seem to be honing onto the nw/se axis with the amplifying atlantic ridge responsible for dropping the trough close to or over us ..... what if upstream isn't modelled correctly and that amplification doesn't come (r

  28. You can count recent cold christmases on the finger of 1 finger..but I think we will add to that this year according to tonight’s ECM 12z ensemble mean!..and whisper it but I think between crimbo / new year could deliver something even more wintry..watch this space!

  29. I’m in no way convinced yet that a decent cold spell will come off considering how many times the models have backtracked from decent synoptics. However, I do get the sense that some people in here could be staring at a blizzard unfolding outside their front doors and still be on here moaning that the uppers won’t be cold enough for snow.

  30. Let's keep to sensible Model Output Discussion please in here, Nothing wrong with a little humour within a post related to the topic. The forum is obviously getting busy now because of the interesting synoptics so we don't want good posts getting lost amongst the noise.. Thanks all, please continue ☺️

  31. I don't think COBRA meetings get called for wet snow over the hills. Ridiculous exaggerations from posters in here, as usual. There's nothing significantly snowy or cold for the majority of lowland UK in that model run, and it's academic at this range anyway. Nice synoptically, but talk of snowstorms is such nonsense. People never learn and set themselves up for a fall when future model updates show less wintry potential.

  32. The first properly exciting model run of the winter. The first one to make me sit up. Notice the all-important Greenland High. Upstream blocking is the key, which wasn't present in previous flashes of cold. It doesn't have great support but neither is it an outlier. Something to watch.

  35. ECM mean and spread T240: Very good. And the uncertainty on the spread chart is now twofold, probably related to heights at the tip of Greenland, but more related to the low pressure across the UK related to the (hopefully) snow storm. We’re getting closer.

  39. I didn't think it looked at all likely. Why so? Because there was no upstream blocking: people were relying on the high pressure in Russia / Scandinavia to turn into sustained blocking here and that's a fraught pathway to cold in the UK. Looking east not west is like beginning a book on the last page and reading backwards to the start. It can be done but it's sub-optimal 🤪. This time there's upstream blocking showing up: a proper Greenland High which is very different. Doesn't mean it will happen, mind you (so I agree about that), but at least the starting position is on much firmer

  40. I'm resisting to throw caution to the wind on potential between Xmas and New Year, looks nice from the 12z runs of GFS, EC and GEM, but can we trust them with how they handle the breakaway vortex heading from Greenland to Europe? Already Xmas day has gone from cold northerly to mild northwesterly on GFS, some spots may even reach double figures east of high ground. With the breakaway trop vortex heading SE, ideally don't want it to grind to halt over the UK, or too far west. Moving SE or S best into mainland Europe best - but we need ridging to build to the north at the same time, not a t

  41. The big wins tonight are: - The Xmas day Northerly has been sharpened up and will bring 60million people in this country not to mention NW Europe some frosty and *possibly* snowy cheer on a year in which they’ve been battered to oblivion - The major models have not gone flat with the post Boxing Day Atlantic amplification, they have all gone for variations on the today’s broad GFS theme, the details of which are unknowable yet. On the negative side - They have still not decided upon the fate of Wednesdays low (or not to low). Fair play @nick sussexyou said it wasn’t relev

  42. I think most people on here know, the second part of any GFS/ECM run isn't to be taken so literally otherwise the word CAVEAT would be used in every sentence. People are allowed to get carried away and have a bit of fun with the second half of a run, it's part of the enjoyment (for most anyway).

  43. This is the big problem though...its been so long since we last experienced proper cold,some just won't have it..Even if it comes up and bites em on the [email protected] they still won't be convinced. Even if we had cross model agreement for a significant cold snap starting tomorrow,some would still stay...ill believe it when I see it...we have to start somewhere.
