Monday 18 December to – Sunday 24 December
Changeable and not too cold

We will see if the models become more consistent concerning the pattern between Christmas and New Year, and if there are any more signs of anything colder developing in early January.

From the met office blog issued today for later next week and leading up to Christmas.

"At this stage, there is very little sign of any widespread or severe cold and wintry weather.”

The chance of a more prolonged spell of cold weather is pushed back to mid-January now.

Before that sentence it does also say, “Later next week and the days running up to Christmas there are some suggestions that the jet stream will drift further south, allowing conditions to turn more widely unsettled. There is also a chance of winds switching to more of a northwesterly direction, allowing conditions to become a little colder, with a risk of some wintry showers developing in the north.”

Which is more or less what we’re seeing in the model output.

Reading between the lines it ties in with the model output which shows cold and wintry weather next week. It is probably not going to be across the entire country or severe cold but it does look like being possibly being wintry across a swathe of the country at some point around the 21st to 23rd and  a White Christmas is a realistic possibility for some favoured parts. Semantics and caveats are the key to the Met Office comments.

Not really, as it ties in with what the models show. The question is though will it be for northern hills or something more extensive?

Well, I think you’d have to say that the prediction is at the outer edges of the model output we can see. Certainly he/they must be discounting the ECM evolution, since that keeps the pattern pretty flat out to Xmas Day; even on the ensemble mean (which brings the cooler air further south), the 0c isotherm never leaves the far south-west and the north of Scotland only gets down to -6c.

Well the showers would definitely be turning wintry in the north based on the ECM output but other output is actually more encouraging if you want wintry conditions.  Here is the (probably overdoing i) snow depth chart for day ten of the 12z ECM run: https://weather.us/model-charts/euro/united-kingdom/snow-depth/20231225-1200z.html 

There seems to be a lot of uncertainty but the possibility of showers turning wintry, at least for northern parts, seems reasona high. When, how widespread, at what elevation, any settling snow etc. all remain to be seen.

At this range however it could still end up milder than average or very wintry (or neither!)

We will look at the prospects for the New Year again, and see whether or not any chillier conditions still look likely.

Interesting that the forecast ends with a snowflake symbol for Edinburgh for Christmas Day.

I see that the low pressure system which is forecast to bring tomorrow's very strong winds has been officially named as Storm Pia by the Danish Met Service, presumably due to the likely effects of that over in Denmark.

In a way, it's a shame that the Dutch didn't sneak in there to name it first as that would have brought it within our own storm naming system which the Met Office and Met Eireann are part of, thereby resulting in that system being named as Storm Gerrit which is the next name on that list.

This has therefore once again, shown the disjointed and fragmented nature of these storm naming systems which once again, has shown that there should be a single storm naming system which covers the whole of Europe.

Completely agree with this.

I see that there is now a snow and ice warning out for N Scotland for tomorrow night for 2-5cm of snow on low ground and 10-15cm mostly above 200m.

Two days later could have been nice!

A wee bit further south would also have been nice so that locations such as Edinburgh and the Borders could also have been included in that.

That always seems to be the way though when it comes to "interesting" weather because it is usually always either too far north (so that it's just the west and north of Scotland which gets it), or too far south (resulting in England getting all of the interesting weather while we miss out on that here in Edinburgh).

This means that where I am, I am hardly ever within the actual firing line of that more interesting which is why our weather is usually always boring and uninteresting compared to elsewhere as a result.

Interesting - the MetO long-range forecast has, for the past few days, had something along the lines of "there's a low risk of a cold spell as we move into mid-January". Today's update instead says this:

"Through January conditions may turn less unsettled as high pressure has more influence. A possible change in weather patterns also increasing the chance of more prolonged spells of colder weather for all areas by mid-January."

It's interesting that this change in wording coincides with the recent change in the ECM 42-dayer showing a much weaker stratospheric vortex early next year...

they cant even get 7 days head correct never mind 42.  Im becoming more appreciative that any model watching out beyond 5 days is inaccurate. A vague whiff maybe and too many variables to be anything more.
What percentage of the charts from 7-10 days ago correspond to what will be on xmas day?
