Well the mornings output shows once again why you shouldn’t bother looking beyond +144hrs, another t*ts up cold spell appears to be fading fast with heights slowly drifting away SE over the UK allowing the Atlantic lows to gain the upper hand in what would be the usual dish of the day fayre.

At least us enthusiasts, can just hide behind our various devices and wait for another day...think how embarrassed the professionals feel , standing in front of millions of people on TV , changing  the media releases and having to wipe the egg of their faces, I have said it before the moment the forecasters openly start saying they are confident this or that will happen, in fact the opposite occurs!

I dont fees offended Neil that’s the way I feel I appreciate the education but not feeling of them feeling awkward about an unexpected weather change.


The weather does what it wants I’m not heart broken about it Life moves on.



 


Apologies if this offends, but that is bloody ridiculous. As professionals they have a duty to be accurate which they do to the best of their ability. And they get paid according to position and years of training and education to achieve that position.

Brian yes that's a fair assessment, however there are those in the outdoor, farming , outdoor and fashion worlds that also listen to every word and when the word "Snow" is mentioned (just like on here) many ears prick up whatever the age of those watching, reading or listening and it does become a hot topic, at school in the workplace, or in the pub....and that is when the forecasters get slated, because they have people's attention and get noticed when it goes wrong. .....in my opinion. 😀

The sad thing for the UK is that the stellar winter charts rarely materialise and the crud ones invariably do. We always get downgrades and any upgrades if we get them, only ever occur in FI, later to be downgraded.


If you want snow, move somewhere it usually does snow. Given the rotten winters we continually experience in western Europe, even the Alps and much of Scandinavia are no longer reliable. Best snow possibilities are in the Rockies and for genuine cold, keep heading east until you reach it.


Yesterday, GFS showed a genuine Greenland HP a little over a week away, with -10 850s over Scotland. The scale of the reversal since ECM spoilt the party with yesterday's 12Z output, is shocking, but typical of its kind for the UK winter. All eyes on the next set of runs, but with any optimism for next week having vanished into mild air.

Forgive me if I am mistaken but my calendar says it is 28th November today.
There is an unbelievable amount of gloom and doom here today for no good reason. We are not seeing raging zonality that looks indefinite. This is not 2015 revisited.
This is a variation on a seasonal theme that is actually quite abnormal for late November.
As long as the longer term signals suggest a continued propensity for blocking in unusual places and a -AO and NAO I will remain upbeat. Winter doesn't even start until Friday....most decent wintry spells invariably don't get seen this side of Christmas.
I think a lot of people need to lighten up and realise the synoptics we are seeing are not normal and it's highly likely with the background signals that all models will struggle to get to grips with what lies ahead.

Our climate has changed and we just have to accept it.

I do find it amusing the way people blame the models and talk about things "going wrong". The weather will do whatever it does, whether or not the computers churn out their pretty pictures or not. I think some people would do well to remember that.

You can't predict the weather more than a few days out, and I doubt if it will ever be possible. Even if you could somehow take a snapshot of the exact state of every air molecule in the entire atmosphere right now, you couldn't predict accurately where they will be in a day's time.


 


A case in point: the 06Z GFS is vastly different to the 00Z even at 144hrs.

When you consider the complexity of our atmosphere I still find it quite remarkable that the models can pick up trends as far ahead as they do. But not reliably.  We will never, I think, escape the proverbial butterfly flapping it's wings.

FWIW the 06Z seems keen to bring in a northerly again. Still high pressure to the south but -10C into northern Scotland by T174.

Very different pattern to the 00Z. Any forks that have been prematurely stuck in this cold spell may yet have to be removed.

UKMO wobbled yesterday and improved today, now ECM has wobbled, GFS wobbled on the 0z runs, but now the 6z seems to coming back to where the UKMO is today. Swing and roundabouts are all part of models looking for the pattern.

With charts like this from ECM it looks like next weeks northerly blast is at least delayed if not eventually cancelled.In the meantime enjoy the next few days of sunny crisp weather.Lets hope that the Meto forecast sticks to its guns re return of northerlies.But bear in mind that for the southern half of the UK northerlies rarely produce any substantial snow.

Rob K
28 November 2017 10:34:46
Northerlies on their own rarely produce snow for the south, but a northerly pattern still can: either from low pressure approaching from the west and going along the Channel (as hinted at yesterday and again on the 06Z now) or (less risky) a system coming down from the North Sea a la Jan 2010.
