Yes in the 80's when my kids were young I remember one organised display in our local park where we standing with snow on the ground and sub-zero temperatures. 14C at 8pm on the 5th this year!  A lot has changed in 40 years and it is now just a vague hope rather than a real chance and that applies to the depths of winter as well!

I can remember being in York in November 2010 with the temp around freezing and snow piling down so fast we had to change our plans for the day and curtail our trip, having an early meal before trudging back to the car in snow getting on for 6" deep.

And I can remember scraping frost off my car twice earlier this autumn.

I'm far from a climate change denier, and absolutely do support measures to control it. And we are getting generally milder overall, for sure. But I also don't want to fall into the trap of conflating climate and weather.

Saying that, I do think the impacts of CC are being felt more keenly in the SE than further N & W. From longer droughts in summer to a reduction in cold and snow in winter.

SST's are the biggest factor in this I think (which would be directly down to CC) Last time the north Atlantic was in anyway cool was in 2015, which was the lag effect of the robost 2013/2014 Atlantic storm season. Even observed a grass and car frost in late July that year (2015). With increasing SSTs, humidity levels are rising all the time which of course will prevent temps and dewpoints from falling as low as they should. I also don't rule out the obscene amount of pre sunrise contrials in the sky in preventing normally lower temps, which I believe is also helping raise long term mean temps both overland and over sea.

Even that ECM run this morning (which some posters were saying would bring snow showers) just had cold rain down here, with night temperatures around 4C. I still look for the -10C 850 isotherm before I start getting excited, and aside from a single GEFS member a couple of days ago there's not much sign of it in the output - not that I'd expect much at this time of year anyway.

FWIW the ECM zonal wind charts have, and continue to show a spell of weaker westerlies aloft at the end of the month - which should dampen the typical Atlantic zonality. I strongly suspect it's related to the outlook turning a bit less warm as we go into the first half of December, and I daresay it's part of what's leading to the current thoughts of higher pressure / more settled weather for a time.

We're losing the normal signal for next week now (unsurprisingly it's warmed a little as we've got closer), but the first half of December still looks likely to see normal temperatures for our 91-20 period - and it says a lot that that's pretty exciting these days!

EDIT: And as an aside, as we've seen the warming trend isn't simply a case of "your usual weather, but slightly warmer", the patterns have changed quite a bit. Put it this way, I won't be anticipating an easterly this year, and I note the AIFS - which is a "here's what would happen in our previous climate" continues to be a wee bit colder than the op when things like the upcoming colder spell are shown. It did that a fair bit last winter, too!

(Recent examples include 39C in the record-breaking heatwave and -14C in the Beast from the East, one was 16C above average and the other was 16C below!)

The lawn growth is relentless, and the herbaceous plants especially are having a second wind, quite recovered from the summer drought. Roses are re-budding and flowering, and yes Dahlias, and salvias still doing their thing, so much so that I managed to fill many vases of garden flowers for a visit recently from old friends.  The underlying aquifers still remain very depleted but the moisture, and warmth are ideal for plant growth. Autumn and spring are now the key growing months, the mid summer is becoming too hot and dry for many stalwarts of the British garden, including a healthy green lawn.  I agree that cold air direct hits - are still likely to be modified by Super warm seas, and elevation combined with evaporative cooling are increasingly necessary for even transient snow - especially non-slushy and sleety snow that settles, even for a short time. Fat chance at 28m ASL, but the areas south of Newmarket across to Cherbourg in Suffolk between 300 and 400 ft and your way too, are far more likely to get snow than lowland areas of Norfolk and Suffolk, surrounded as we are with the warmed North Sea.

Now exceptionally rare if they have existed at all in the last decade.

The good news is, in my experience, even though the 'least interesting synoptic pattern' tends to end up being the right one at this time of year; the uppers always tend to be a bit pessimistic and upgrade closer to the time. First worry about getting those 500hpa heights in the right place, then closer to the time we can worry about where the isobars are pointing from, and only then should we start thinking about the airmass temp.

Also the S.E and EA are much more plagued by High Pressure cloud in both summer and winter and now, whilst still not as hot, the SW in particular seems to do much better for sunshine.

But in terms of real blockbuster cold and snow and blizzards the halcyon days from the 40's to the late 70's and early 80's just aren't happening. When you think of the intervals between the monumental winters 1947 and 1963 and the blizzards and cold of the 70's and 80's the next gap was really to 2010 and that was nothing like the previous epics.  So they can and likely will still happen but the interval will be more like 50 years than 15 years I would imagine.

I think that is probably a fair assessment of the decreasing likelihood, at +1.5 degrees. How this seems to manifest - is that primary cold blasts are now never enough to embed cold. You need to have 3-4 stacked up blasts, possibly from multiple origins, i.e. especially deep arctic air from the north, rather than a casual drift of cold on a SE airstream importing continental cold - as used to happen in my youth (60s - 80s). Initial blasts of cold get highly mixed and modified, and need a second influx - Scandi to Arctic or similar. I remember that we had something like this happen in 93? Or similar, and a Scandi high developed  and it was really only the last puff of many that actually brought snow in from the east, as before this the cold air was highly modified on route and we had sleet and rain. I’m not sure that would have been snow today, in 2025, as the air seems to need to have an Arctic origin for uppers to be cold enough and dew points  to be low enough. Just my thoughts and obvs, and may be not backed up by facts...?

Swings and roundabouts with the ECM outlook today - the latest medium range charts now show December's average spell trending slightly warmer, but the average spell from the 17th has trended colder. Indeed, there's some rare blue shading over the UK for once!

https://charts.ecmwf.int/products/extended-anomaly-2t?base_time=202511080000&projection=opencharts_europe&valid_time=202511240000 

That'll be quite the shock considering the exceptional warmth we've had lately (and will continue to have next week).

EDIT: And the zonal wind charts continue to tick down, which is good to see (from the POV of someone who likes colder conditions). There seems to be some clustering going on too, with around 70% bringing winds back up and the other 30% keeping them lower than normal. Either way, it should make for a change away from our seemingly endless warmth this year.

While SST's seem to have moderated a little over parts of the North Atlantic, they're still very high to our North.

As the charming DEW is still on his travels, I’ll have a last go at the model roundup in that style – I too am going on my travels next week (not with DEW obviously – I hardly know him …. your honour)

FAX – Current set up shows a triplex of low pressures in the mid-Atlantic 987mb, 996mb and another 987. These throw a complex set of fronts across the west side of the UK which will pulse rain along them from south-west to north-east. By the 11th the three parts of the Low area have split – one has gone down towards Iberia 975mb, one has gone over towards Denmark 995mb, one remains north of Scotland 993mb. Still southerly flow, still mild. By the 13th (end of the run) there are just two cells remaining off Iberia 884mb and Finland 981mb. These two provide an occluded front from south to north, with a mild airmass covering Wales and England; and a cold from coming from the north covering Scotland. Bit of a battle-ground forming when these two front meet. The next FAX will be very interesting to see how this develops.

GFS – matches the FAX over this period – low pressure dominated, with the duplex Low pressures to the southwest and northeast of the UK. North winds to the north of the UK, south winds to the south of the UK. Day time temps 5 to 10C in the north; 10 to 15C in the south. Overnight temps -1C to -2C in Scotland and generally -1C/+1C in England/Wales too. Yes – probably the cold is coming. By the 14th, there is an Iceland HP 1025mb in position and most of the UK is under Easterly winds – getting to -5C over Scotland and +2C over the south. By 19th there is a real north south split in overnight min with -7C in highlands, +7C around London. By Sunday 23 November the Iceland HP has dropped down into the semi-perm of the Azores High and the UK is on the cold side of the jet. Gentle LP crossing the UK 1005mb giving several rain ‘happenings’ – but this is getting into FI-Land now.

ECM at 120Hrs (14th Nov) is giving good cross-model agreement showing the two LPs – 985mb mid-Atlantic and 970mb over Finland; HP 1030mb just south of Iceland. UK under east/south-east winds and getting cooler. The HP from Iceland does drop down to the Azores, but it does it through a more circuitous route over the UK and Spain. By the 19th Nov, the UK is on the cold side of the jet forecasting low single figures and certainly rain, but probably that good old ‘wintry-mix’ in the north and on higher ground.

 

GEFS ensembles show very mild to 16th Nov, +6/+7 over 30 Yr mean, then a quick decline, now going below the 30-year mean. Noticeably good agreement for this out to 17th Nov, then the average does go down below the mean from 17th to 22nd. More rain spikes than a flowering cactus to 17th, then a dryer few days before more spikes from a smaller cactus through to the end (25th). Down south the snow row does give a 4 and 3 around the 20th Nov; Glasgow snow row gives 9, 4, 6, 8 over that time; Inverness gives a prediction of a potentially enjoyable 11, 18, 23, 14, 19 over 18th to 22nd Nov. The average is below the mean in Scotland from 13th through to the end of the run (25th), so the cold looks more certain there. Good luck guys.

ECM AIFS London, predicts daytime 14C for London and 11C for Glasgow on the 12th November; dropping to London 9C and Glasgow 3C for the 17th and by the 25th London overnight has +7C, while Glasgow is showing -5C. At the end of the run there are big fat 0 for precipitation; the earlier dates around the 17th there is only a little rain in the north, but more in the south.

Happy weather watching – the first chase is upon us, but a bit early to get carried away.

The latest zonal winds prediction is fascinating, with the mean now down to 5m/s - and a decent chance of a reversal. It couldn't be happening at a better time of year IMO, as even without a reversal it'll be quite a hit to what would normally be the "ramping up" time of year in terms of the vortex.
