Most models now not showing anything significant for the south east in the predictable future.

Growing concensus on a Midlands to North England snow event Thursday/Friday.  Very frustrating for here as I'm to far south by the looks of things. 
After that difficult to say but likely more tedium.  Roll on Spring warmth

GFS last two runs has stalled the low over the UK which creates a headache for those of us who were looking at a clean easterly going forward (decreasing possibility now).

Here we go, yet another cold snap that's proving impossible to forecast. What's happened to make the GFS remove the Scottish Easterly with 3 days to go?? That model shows milder southerlies now until the end of the 0Z run?

The other models including ECM and MetO are still going with a cold east then northeast for later this week for N. England northwards but do I trust them now the Americans say no?

This model watching has been so cruel to us that want cold and snow since November. It's turned out to be the 'Winter of Wind' instead!!

Anyway, fingers crossed.......rant over.

Not much cheer for coldies on the WX charts. Freezing N of the usual line from S Sweden to S Urals, some very cold weather in the N of this area but even in week 2 less extension of cold weather into NW Europe and Britain remaining mild through both weeks. Pptn in week 1 for all Atlantic coastal countries and penetrating some distance from the coast, Britain getting the heaviest; in week 2, the wet area retreats to more limited coastal areas, plus a local heavy fall over Turkey.

GFS Op - LP moving into Ireland 970mb Fri 9th slowly drifting N and filling by Tue 13th as HP moves up from the S, not connecting with any really cold air. Ridge then develops from Norway to Britain, quite strongly for a while, fading but still the main feature for Britain Wed 21st.

ECM - similar though The LP on Friday is further S (SW England), with light E-lies for a while before moving away NE-wards. The following HP brings up air from the S or SE, the latter more so than GFS

GEFS - mild for the S until Sun 11th then temps near norm, rain for 3 or 4 days from Wed 7th, damp thereafter, no snow. Scotland temps dropping to cold until Fri 9th, then two groups of ens members for a a couple of days, one cold, one mild, before a general scatter about the mean on the norm from Tue 13th. Less rain on 7th than previously thought, more for the period after Fri 9th with best chances for snow at the start of this. N England has a briefer dip in temps than Scotland, and good agreement on mild to follow. Modest chances for snow, briefly, at least at low level stations.

It will, by the look of things, take a few more runs to get a clearer picture for day 5 and beyond. Before then Thursday could be snowy for much of N England.

I personally think the UKMO model is often a good mid point between divergences in model outputs from the GFS and ECM.
However, today the UKMO output maintains the least development of the incoming low, and delivers the snow event for much of the south (marginal as it may be).
The ECM delivers it but only for the northern half of the UK, but the GFS develops the low to the extent that it changes the whole game and the cold air is kept off us like the force field that surrounds the goal of any team Ipswich Town play at at the moment!!!
I fear that the GFS is best adjusted for the modern climate changed overly heated seas - and hence the low inflates like a balloon at a fairground!I
My hope however, that my old faithful UKMO model is the correct one, although it doesn’t look like a long spell of coldish air over the UK even then.

After the snow event on Thursday.  There really is no significant cold forecast. Decent blocking perhaps but cold 850s and 2m temps don't look likely to me. Here at least.

Almost a decent Scandi high at the end of the op run but heights to the south ruin that idea!

The run suggests colder than normal for the middle of February, if not notably so.

Have to say, the 'snow event' is looking very marginal at low levels, slushy mess to me. Good for elevated areas for a while though.

Now compare it to today's 06Z here:

https://www.theweatheroutlook.com/premium/gefs-tables.aspx?run=06&fv=tmp850&loc=london&lat=51.5&lon=0&p=&cty= 

You'll see there is a good deal less purple in the columns on the 06Z update. I agree it could be a different story for locations further north.

EC En's average for snow accumulation. Shows how much 'scatter' there must be at this timeframe as virtually everywhere has a chance of seeing some snow at some stage.

In simple terms its a battle between GFS and most of its suite (stalling low, snow to rain North only) and the majority of the rest (UKMO/EC/ICON for example that clear the low ESE, snow stays snow N Midlands northwards and all colder by Saturday.
Again we’ve got a standoff, no clear cross-model consensus and therefore no one can be that confident about conditions from Thursday let alone into the weekend.
Tricky forecast to be fair.
