I take your point, but years of bitter experience have led to fear that we are stuck in a never ending rut - groundhog day without the snow.


Once the euroslug makes an appearance in November, we know that it can last all winter. That is not to say that it will and for Heaven's sake, let's hope that something happens to kill it and change the pattern. But you can understand why people get despondent at this time of year, since we know that once this pattern takes hold, it never seems to clear off.

OK, I know that this time last year we did not have a strong El Nino event taking place as at present, but we had almost as poor model runs from a coldie's point of view and some were saying "It'll be a re-run of last year" (2013-14). It wasn't though. Where I live it became generally much quieter, drier and somewhat colder from mid-January onwards and we even saw a bit of the white stuff at times.


On topic: The GFS 12z op is rolling out now and from what I've seen thus far, it doesn't suggest abnormally mild temperatures for Scotland next week. I'm not saying we'll get a white Xmas but with the jet further south than this week, I imagine that the mountain tops in Scotland may see some snow. Nearer average temps up here, I would think.

Im keeping an eye on Xmas day and the days either side.

Something starting to hint at a wintry type event around then.

Charts are showing Cold air nearby and LPs running across the UK, those ont he northern Edge could get a snowfall similar to Saturdays surprise. Would mirror last years Boxing dasy event for north midlands.

Ensembles have a bit of an increase on the snow row too around that time

http://www.theweatheroutlook.com/charts/gefs/gefsens850liverpool0.png?cb=520 

Would be fascinating if people got a white xmas in one of the mildest Decembers on record.

Also - anyone noticing that FI is continuing the theme of the Euro slug heading north, bringing more of a SSE wind, wouldnt be cold, but would be dry and Mild.

Would also be knocking on the door of an easterly.

Not long ago a read a comment by NOAA that the model tends to overcook areas of low pressure that are crossing the U.S. with a consequential amplifying effect as ridges into/across the Atlantic are enhanced.


It does tie in with my own suspicions too

There's a ongoing, huge El Nino going on - there's excess energy (warmth) in the atmosphere and it's effect are only just taking hold. We're also in a spell of weather that has pushed warm air well east and north of us. Something very similar is going on in N America. It takes weeks for a cold spell to happen/establish here (if at all) in such circumstances.

Well I've already been proved wrong on one thing. I suggested this thread will last all winter before reaching 50 pages and after 5 or 6 days we are already approaching 35 pages so obviously it is still interesting model watching, even if not what the majority of us want to see.

XMAS ens now have 90% zonal and 80% mild so not looking good for a white one.However five days later build up of pressure to either  south or east giving 50:50 zonal:anticylonic flow and around 45:55 mild :cold

I love Cold weather Jacko but I love model watching also I cant see the point in getting upset about it the weather will do what it wants im sure many of us have had many hard personal times which really means the weather is not that important really.


anyway for the mildies you would be pushed to find a warmer Dec looking east than that.

Hi All, been monitoring the site for years but only just got round to sorting my registration!


Looking through the charts, this really is a depressing one for me!


Making it worse for me is that fact that im due to go Skiing in the southern Italian Alps (Sauze D'oulx) 17th of January and I just cant see this HP being shifted and them receiving any snow!


Originally Posted by: Graham Swanton

Sauze D'oulx is a lovely place.  We went a few years ago during February and we hadn't had a flake of snow here all winter, until the morning we set off for the airport.  The same happened this January, we set off for the Caribbean in the first snow of winter, then we were away again for the heatwave here on 1st July.

There is nothing wrong with so-called mild ramping any more than there is anything wrong with cold ramping, as long as it is kept within the context of model discussion. Polar Low did this by including a chart to back up his point, thereby making reference to the model output.

The forum normally tends to be somewhat busier anyway at this time of the year generally than any other, hence my point.

O/T somewhat but John Hammond just mentioned potential record breaking temperatures later this week, by that he obviously means December all time record could go. As I've said, the GFS has been remarkable in its consistency in progging temps around 15-16 degrees for this Wednesday and Thursday. It started showing these sort of extreme temperatures way out at T+288 and now we are within 72 hours. That is a very exceptional performance from GFS model if as it appears likely, it does now verify.
Add on a degree or two with that bit of sun and Foehn effect and that is why John Hammond just mentioned that the record could well go.
So if it does, this is much cuedos to GFS which has been incredibly consistent this month. It is obviously as previously mentioned much easier to confidently forecast these zonal mild patterns as that is the default pattern, but it is quite another to accurately predict 12 days out some record breaking temperatures.
If they come off, hats off to GFS in my view.

From December 27th 2020, zonality will be banned from mixing with the UK. We appreciate that this may come as a shock to younger people and old Uncle Barty. This ban will last for a minimum of ten days.
