Just like 2 years ago if the charts posted by Squish verifies. Had snow in Sheffield, with severe blizzards in the hills just to the W. Hallam moor recorded a max of -1C on 27 Nov, c.f, 3 C in Sheffield city centre.

As I said before, GFS is a false friend to those who would like a proper northerly. The 18z shifts the northerly blast eastwards, as so often before; Denmark gets it, we don't. Even ECM 12z only gives Scotland a quick blast (one day only) before moving the seriously cold weather eastwards.

Laughable isn't it. It won't be the only time in the coming winter that the GFS does an about-turn.
My policy this coming winter is not to believe anything the charts show until its within 72 hours!!
For my sanity, I think that's a good idea.

WX temp charts - no great change from the last few days with most of Europe just above norm except that Scandinavia remains rather cold. The (normal) freezing weather over N Russia keeps threatening  to move in but only makes slow progress into C Europe with some effect on Scotland too. The rainfall pattern is much as yesterday's chart, too; a large area over Britain and Germany  (but see below) and another around the Black Sea, not entirely dry in between.

GFS Op - starts consistent with yesterday, Lp in Channel today supplanted by larger LP from mid-Atlantic which traverses N of Scotland and down the N Sea into Europe by Tue 21st. Contrary to WX above, HP sets up to the SW of Britain and stays thereabouts to Sat 2nd while LPs run from Iceland down to S Sweden always leaving Britain on the fringe of a N-ly flow but essentially dry.

ECM - similar though Sat 25th sees a one-day closer approach of the N-lies cf. Brian's chart above.

GEFS - briefly mild around Sun 18th, and perhaps Sat 24th,  but back to norm between and little agreement after though some suggestion of a cooler early December. A pulse of rain for the S now, more generally on Sat 19th, rather dry thereafter.

Quite a common theme each year - decent cold charts show up for beginning of Dec seemingly forgetting about the key driver of the weather at this time of year the PV! Fun looking at some of the output while it’s there though - rapidly disappearing now

Wonder except for the occasional meander the forthcoming three months will see the high  keep its shape and locate somewhere in the region eastern central Atlantic south west of UK.Scandinavia will be in the freezer and occasional incursions of cold air to the north east UK. The rest of us it will be another " What if winter of nothingness ".

That has been the main reason that colder air fails to flow sufficiently south. Sadly, for those hoping for seasonal winter weather, the climatological trend is for higher pressure to our south due to climate change; Brian posted the evidence last year. It doesn’t stop cold spells but it makes them less likely.

That said the weather is weather and never say never and all that.

6Z GFS tries to bring in an easterly after the brief northerly - not a lot of cold air around though, so still far from wintry down here at least!

She was born Feb 08 so sadly has no memory of either the Dec 09 or Dec 10 snow. She does remember Boxing Day 14, though, which is something.

I'd love another December 2010.

Snow at Christmas is just magical.  We had 5 inches last year about two weeks before. I told my boys 6 and 8 at the time to drink it in as its so rare. Driving home in the dark that week with people's houses decorated with thick snow everywhere was just bliss. 
Who knows when that will happen again here could easily be 20 years.

1970 was the last time there was a Christmas card scene down here, i.e. snow falling and settling on Christmas Day. That was several years before I was born, and I'm now in my mid 40s!
Since I became sentient I've seen a couple of flakes (literally a couple) fall on Christmas Day one year, one year where there was some snow still in the garden (which made my day!) and another where I drove two miles to the hills nearby to see some snow on the ground, it having failed to settle IMBY. I would love to see a proper Christmas scene - at home.

As it'll be 53 years this year since it last happened, I don't fancy the chances. I suspect I'll be dead before it happens again, but hey... one of these years Kent might just get lucky.

Back to the here and now, I note the storm which the models had been showing for today ended up passing to the south (there were orange wind warnings in France as a result, they named the storm "FREDERICO"). This is good news, as it's been a long time since the last low went south of the UK - meaning the novelty of easterlies and NE'lies for a time today, together with that orangey glow in the sky as the sun set and the rain poured down. An omen for winter, perhaps? Certainly if it'd been 8 weeks later those of us in the south would have been on lamppost watch this evening!

As for the models further out, they're still coming to terms with the next big pattern change. It remains to be seen where the long-wave pattern ends up, but an Atlantic ridge of some magnitude seems to be the most favoured outcome IMO - whether it ridges far enough north to bring noteworthy cold remains to be seen (some of the GEFS over the past couple of days have brought the -10 850 line south over England), but as we all know - unlike damaging winds, or dangerous heat, those cold outliers seldom seem to come off!

If nothing else, though, at least we should see less in the way of rainfall for most - and I'm sure that'll be a most welcome change right now!

More annoyingly, we were flying to Paris that morning for a long weekend. Snow moving in from the west. We had to wait for a de-icing and, as we were waiting, the light and not-lying snow became heavier and started to stick. The incompetent arseholes at Manc Airport closed the runway, supposedly for an hour to clear the runway. It maxed at 1cm deep. They kept it closed for 4 hours. Our flight got cancelled. Managed to get on another, but lost a whole day (out of 3)

Indeed. The impressive thing was how well the snow lasted through the following days. In some ways I thought it was better locally than the 2010 event.
Anyway, GFS is still not without interest this afternoon, but as usual it is heights to the south which ruin things. This really is the bane of the "modern era" as far as cold weather in west Europe is concerned. People can work themselves into all sorts of contortions to produce complicated explanations of why X, Y or Z in some far flung part of the world will lead to cold weather in the UK. However, ignore the basics at your peril - the high pressure belt to the south is steadily extending northwards.

I'm not sure whether it was you, but I remember last winter someone posting a chart showing the rise in 500mb heights, I think it was, over the past few decades. It was stark and showed exactly what you're saying.

As for the wiffle about "teleconnections", I always take them with a pinch of salt - I sometimes think over on the other channel people throw around those technical terms (MJO etc) just to make themselves look good. And no, nobody's yet cracked it - for whatever they say, however good the moonsoon in India might be, or however high the anomalous heights over the Arctic rise, or how perfect the tripole anomaly might be in the Atlantic, it still seems to be harder than ever to get a proper wintry outbreak.

It can still happen, of course, but it reminds me of that game you used to see in shopping centres (roll dice to win a car). Instead of getting three sixes out of five dice, we now need four or even five out of five - purely to counter the inevitable rise in temperatures (and increased heights), plus the knock-on effects of these, which define our current climate.

One member whom I will not name seemed convinced that such spells were consigned to the history books as winter pressure patterns would no longer allow for it. Little could anyone have envisaged at that point the events of two consecutive winters as we ended the first decade of the 21st century and moved into the second. The events of Dec 2009/Jan 2010 and then December 2010 were certainly a big surprise to me when they occured and not something I would have bet any money on happening a few years beforehand.

As someone said further up this page, the old saying of 'never say never' still holds true when it comes to the British weather these days just as it has done at any point in times past.
