Quick post re the GFS ensembles. The mean for snow cover for a week’s time shows some snow on the ground across the entire country, away from Cornwall and the far west of Wales.  Quite unusual - and the op has much less across the south.

ICON gets the 0z output off to a good start (if you're a snow fan). There's widespread snow on Tuesday into Wednesday, then more snow on Friday - albeit that heralds the return to milder conditions and thaws quite quickly. It's still more interesting than the usual "ridge moving in effortlessly" sort of breakdowns!

Here's the snowcover chart as of Friday morning.

EDIT: GFS also has a set of fronts crossing the country on Tuesday into Wednesday, but it's a slushy mix of rain, sleet and snow.

Now *this* would be a day that would live long in the memory! From the 0z GFS for here - sleet, some exceptionally heavy snow with near-gale winds, then light rain for the rest of the day - as well as a physically impossible dewpoint. 

Of course it won't happen (even without the dodgy dewpoint), but it shows just how much soggy snow you can get *if* you're just on the right side of the rain/snow divide.

One of the other things with the 0z GFS and GEM too, for that matter, is how the deep snowcover modelled over Scotland and northern England isn't going anywhere any time soon - the former keeps it there, largely untouched, out to 300 at least, while GEM has it being slowly nibbled away but still largely intact by 240. Looks like a truly classic spell for some!

From the GEFS this morning, this is the "snow risk" chart with the highest probabilities that I can see - more useful than the mean.

Their "risk of 1cm or more of snow on the ground" chart is lower-res, but gives an idea - here it is at 144:

...and while I'm here talking to myself (😁), the ECM is wet rather than white for most of us - not very inspiring, frankly. EDIT: Same goes for the MetO.

I’m still not sure what to make of the output beyond the next few days. Chilly certainly but apart from that the specifics remain elusive. I know the hills and mountains up here look like remaining snow-covered for the foreseeable future.

GFS offers some hope to extending the cold. But I have my doubts.

Looks messy and not sure what to expect next week really. Though after all this dry and cold weather here, would rather a messy and marginal setup for the chance of a decent snowfall.

FAX - the weekend continues the N-lies with east coast troughs and Pembrokeshire danglers, and then on Tue LP moves across Ireland 1006mb Tue 6th, keeping the N-lies going but much weaker. This moves away E-wards quite quickly and the final chart for Wed 7th has LP 987mb Greenland pushing a front into the cold air over Britain (which could be a messy mix of rain and snow).

GFS Op - the LP on Wed 7th is over Orkney 1000mb, sticking there and deepening until displaced by the winner from a complex set of Atlantic LPs (not a clean sweep with a front as FAX) gets to N Wales 980mb Fri 9th (looks cold but probably snow only for hills). This withdraws NW-wards leaving Britain and a large area from Iceland to Norway in no mans land for any pressure differences, and not that cold for the time of year. Eventually HP builds from S Norway to Britain (but slipping S-wards) Sun 18th1035mb, SW-lies for Shetland, E-lies with a modest cold pool for England.

ECM - follows GFS to Fri 9th but that LP deepens and moves NE, not NW, to Scottish Borders 970mb Mon 12th with some colder air entrained. Instead of slack pressure and mild air, there are a variety of cold LPs eventually the strongest is 985mb S Ireland Thu 15th bringing in NE-lies until HP noses back from the Azores Sun 18th.

GEM - the LP Wed 7th pushes on E-wards, but to 980mb Holland Fri 9th before filling and being replaced by a conventional Atlantic depression approaching W Scotland Mon 12th.

A good time for model comparisons, all predicting something different.

AIFS - London maxima close to 0C for the weekend, then with some variation mostly 5C, rain Fri 9th/Sat 10th and again a week later. Edinburgh, stays close to zero to Fri 9th and again Wed 14th, slightly milder before and after, some snow probable Wed 7th and periods of rain thereafter.

GEFS - mean temp about 8C below norm now, rising steadily to norm or a little below from Mon 12th, but little agreement of ens members by then (op notably colder). Rain in most ens members from Wed 7th, possibly snow in the south at first, more likely snow in the north then, driest in the NE (which along with the E coast has some snow before the 7th)

A bit of a muddle this morning - you'll need to look for yourself and pick your favourite😊

As Darren mentioned in his earlier soliloquy (🤪) it's generally just the wrong side of marginal down here in the mid term, although most models would I suspect bring a wintry mix for MBY at times. It's pretty unusual for me to see proper breakdown snow so I guess not surprising to see most of the action modelled to be where it usually is (some way north of London).

Other than a slight tweak to the temps/setup so that things are a bit milder down here the bigger picture remains generally similar and as it stands somewhere is likely to get a decent fall, even if temporary.  There's also some really fun overnight temps modelled at times over the Scottish snowfields. The ens look okay although I can't see the ECM set on TWO at the mo again, just the deviation which suggests they're broadly as they have been I think. MOGREPs is fairly consistent with the 12z set - temps around 5c down here post the northerly phase seem favoured but worth checking out the little light blue fella who keeps it much colder and has snow depth just over 20cm for London and a very cold night following! I'm not sure what parameters the snow rate uses but there's a lot of spikes for London, suggesting some wintry stuff falling although bluey aside not a lot have lying snow (2-3 I think at various times).

One thing I'll look out for over the next few runs is if there's more hints of HP setting up over Scandi. All the models seem to be toying with the idea but on this mornings op runs at least nothing overly fun comes of it other than GFSs FI effort, which is a bit grudging but does bring decently cold air in. 

Looking IMBY there's been a fairly persistent signal for a little trough/feature to move down through parts of Wales, southernish Northern England, the Midlands and into Southern England and potentially MBY on the 4th/5th Jan. 

UKV has it as a trough with a line of convection sinking south but not very organised so very hit and miss. 

GEM has a more organised feature but it breaks as it heads south so may miss me. 

GFS looks to have it further west and then springing to life as an organised feature as it hits the French coast (sigh). 

ECM has nothing for most, maybe a brief period of enhanced convection for Wales and the far SW albeit showing as wet for most.

UKM does have it and more organised than UKV (I assume it's a resolution thing and UKV should be considered more likely?)

Arpege also has it although a bit further west so likely missing me and again it peps up as it hits the French coast. 

Something to watch I guess although it'd only be another dusting if anything reached MBY I imagine.
