Seemingly - this shallow low was a lot more extensive than was predicted, with snow right across the SE, as far north as Lavenham, Suffolk. Settling snow south-east of London: here is the web cam for Tunbridge wells showing snow, but not lying. https://www.freewayfastfit.co.uk/apps/livecam.html 
The GFS shows some snow for East Anglia later in the week, but I think we might miss out this time. The SE has done very well this winter: two shots on target and both hit the back of the net.  I got chatting in the pub with an even older timer than me, and he remembers many winters the village chaps were assigned spades to create a working party to dig out the roads. Evolving signs of a flaccid easterly emerging, which could develop further. We might get a flake here then.

High pressure looks to be moving in after this little spell, frost and fog could well be the main problem as the high looks to find a new home. Hopefully it'll find it's way upto Greenland to enable some of the cold air to flood south.

ECM ens IMBY show why placement of the HP cell is key, post the next few day's colder weather (and whether it removes any surface level cold as the HP builds) - yesterday's ens set was chilly, today the majority cluster at T2M level is average to mild. There's hints of a slight cool down circa 26th Jan so maybe backing up GFS ops idea of HP ending up further North as cells move in from the West and reinforce the HP near to us.

All in all I think (as Neil posted above) there's only a low chance of HP being anywhere favourable for bringing cold upper air over us, a somewhat higher chance of it bringing colder air at the surface, which is more likely the further south east you are. Overall though I'd favour average to mild post the colder interlude for most peopple if I had to make a punt just based on today's models although I think there's far too much uncertainty at the moment to have any real confidence in the mid to long term.

GFS 6z trying it's best with a easterly late on. Does seem the type of set up that could produce an easterly quite quickly.  No significant cold on the continent yet though.

GFS really isn’t far away from an easterly on the op run, although there is a trend for the high to sink a little before reasserting on a more northerly setting. Maybe it won’t get mild in the east

I know they always have so much hatred with snow and cold and always want to avoid or in the hurry to go away.  In the past when we had no internet I used to rely on the German Channels weather teletext that came under Astra which had ample information for UK and knowing when we will get cold weather on the way here.

Quite a bit of consistency across the 12z models at T144 but can we expect high pressure to hang on in subsequent runs with the threat of an easterly of sorts?

Finally some proper cold air to the east on the GFS op run - will be a long slog to get the real cold here but it's looking slightly better.

A random skeg through the GEFS and there are a surprising number of HLB solutions and decent looking Scandy builds.
I might have to reassess my take on the next few weeks.

i think we could be walking into a cold spell similar to Feb 86 but small adjustments could mean extremely mild. Blocked is definitely the favourite where it sits…..

I think the current suggestions from the models of a spell of HP dominated weather will be very good news to those areas that have been affected by flooding lately, whether it is of the cold or mild type.

At the weekend, I noticed that a lot of rivers and burns in my neck of the woods are swollen after all the heavy rainfall there has been since Christmas and I imagine that is the case in many other areas. In view of that, I think a spell of settled and dry weather is rather more of a necessity just now than a wintry spell.

Do not know why I can not quote a reply in my post, but when you get a poster admitting that they know little about SSW's yet before hand the poster talks about the guff and bluster posters talk about when there is a reasonable chance of an official SSW, split vortex or displaced or just major stratospheric warmings in general that can alter the dynamics and synoptics on a large scale in the troposphere then it should become very apparent that this poster is a complete and utter nob.
like any upcoming SSW, split vortices or displaced vortex it is a watching  brief for now but if like me you are looking for a memorable potent spell of wintry weather then things are starting to look very very exciting. The displaced and split vortices being forecast towards the end of the month ( yes it is just a forecast at this stage) look to put the UK and Europe in prime position for a possible severe wintry spell of weather.

The op has support from a small set of ensemble runs looking to retain cool uppers over France with an easterly feed beyond the latter part of next week. Be interesting if this trend continues. Rain / sleet showers building over the Channel islands as I write.

Back to the weather. It's increasingly likely that its going to settle down judging by the ENS, Where and how the high pressure sets up is anyone's guess?

Blocked and settled by the look of things. In January can mean freezing fog which could mean very low CET. Will be nice to lose the rain for a while!

Increasing agreement on high pressure setting in with the GEFS mean for London sitting above 1030mb from the weekend almost to the end of the run. Looking like the high will be too far south to allow any real cold in from the east but that’s far from settled (no pun intended).

WX temp charts remain unstable; more generally cool over W Europe for two weeks but actual freezing conditions more localised than  shown yesterday, mainly restricted to Alps and areas close to their north. E Europe is above seasonal norm, just about freezing week 1 but with an advance of very cold air in week 2. Week 1, pptn on Atlantic coasts and in the Adriatic, in week 2 these move apart, in a NW and SE direction respectively.

GFS Op. Current large trough of LP over Britain fed by cold N-lies weakens and begins to move off SE-wards by Thu 19th to be replaced by ridge of HP from SW extending from 1030mb Azores to 1040mb Finland, SW-lies (and a little rain?) for NW Britain, weak E-lies for the south. The HP re-organises itself  to be centred 1045mb Scotland Thu 26th drifting slowly SE-wards and giving Britain a long dry spell but back to zonal weather at the very end Thu 2nd

ECM. Like GFS but the cold pool over Europe around Mon 23rd is closer to Britain and may affect extreme SE for a day or two

GEFS. Cold now (ca 5C below norm) rising to norm by Mon 23rd , less abruptly than yesterday ( a couple of days sooner and more abruptly in Scotland), mild for a few days, then mean temp on the cool side from Fri 27th but little agreement between ens members at this stage. Very dry generally, some rain in Scotland  around Thu 25th, plus a bit from time to time in the far SW.

Where will the high end up? This mornings ECM hints at Greenland at day 10 but I'm thinking we could end up with a proper Scandinavian high early February.
