On Xmas Eve, there's just one single pert dupping below -5c; on Xmas Day just two.

That's very discouraging.

GEFS 06z looks quite mixed and often rather mild. With that said I wonder if we could see a brief colder interlude coinciding with Christmas day itself.

I think we can now definitively say that there is no chance of a cold spell over the Xmas period. We will have to hope January surprises us with something.

Totally disagree. A number of runs have shown a cold vs mild battle with snow for central areas. 

Mild looks most likely but there is nothing definitive about it.

It’s just one run in a flip flop period of uncertainty - but the BBC are calling it for mild to be sustained for 5 days...on the 1pm forecast... Not sure what they are taking as sufficiently definitive to make a call, but of course, it is the default position. However, personally, I would not be at all surprised to see a flip flop again the other way - back to a colder outcome or at least mixed, with the Uk being the common battleground between warm and cold air. The north Midlands seems to be the new M4 corridor - for such battles.

We're now reaching the model runs where if it doesnt start appearing consistently soon, then its a bust.  too much flip flopping - which from experience only has one outcome - the mild one.

Either show us some more tittilation, or its a bust IMO.

Hopefully this upcoming cold spell doesn't wipe out the snow cover in Sacandinavia and NW Europe. This has been more extensive this year at this stage than in recent winters. Always useful if we do get a North Easterly. Nature is not always a reliable forecaster but we tend to see bigger flocks of Redwings and Fieldwares in colder winters and this spell has brought massive flocks to the snow covered parts of the S.E.

12z out to +168 markedly similar to the 6z in terms of the UK'ish wider region. Angles the low to our NNE slightly differently, which changes the shape of the finger of very cold air coming in from the NNW. On the 6z, it's repulsed by the development of the next Atlantic turd that plonks its malevolent arse down to our SW and pumps mild crap northwards; on the 12z, it's sadly the same end result.

Fecking heights over mainland Europe/Med again. Stiffs us every sodding time. Ideally need the lows to be crashing through mainland Europe and reports of persistent rain across Spain/Southern France/Italy/Balkans.

By Xmas Eve, the -5c 850 line is pretty much the Scottish border. The -10c just south of Shetland.

Problem is, that low to our S/SW seems to have moved in for Xmas. Unless it shifts its unwelcome ass - and per both the 6z and 12z, that's not going to happen - Xmas in E&W will be crap from a weather perspective: wet, mild (7-10c maxes away from the far north of England), windy.

Where's the sick bowl?

Still fine margins in the output this evening and given the timescale until Christmas it is far too soon to say with any confidence what to expect. Before then a couple more cold days then a transition to significantly milder weather for 2 or 3 days. After that around day 5 confidence would have to be low for another few days I think. 

As things stand northern parts look chilly on Christmas Day itself with some snow around but milder further south. That could however all change over the coming days.

The 12z is turning rapidly into a proper shitshow (unless you're in Scotland)


Find the route back to a sustained cold and snowy set-up from this... 😣
