It would be nice to watch some temporary daytime snow falling but it's not really what most were hoping for or expecting two or three days ago.

TBF I'd take just a snow flurry - it's so darned rare to see even that these days!

The 12z ECM is out to 180 or so and it shows a snowfest north of the M4 on Friday morning - albeit temporary, but even so 10 or 15cm of snow will take a while to shift! Nothing of note over here, of course.

Needs to shunt a couple of hundred miles south before then please!

Would be nice! That low is looking pretty potent, and no wonder... look at all the moisture wrapped up in that warm sector, no wonder things will go "boom" (so to speak) as it engages the cold air over the UK. 

It's one heck of a contrast... here's the dewpoint chart for early Friday, from 8C to 1C dewpoints in about 20 miles.

Depending on which model you favour we all (excepting Scotland) get the chance of very heavy snow and possible blizzard conditions on Friday. 

However whether it's the North of England or the South Coast is anyone's bet at the moment. 

My money is on the GEM - cos it's the best for my backyard! With the UKMet a close 2nd.

One things for sure between now snd Friday there are going to be a ĺot of excited and disappointed people. Strap in for the roller coaster! 

Awful stuff.  Just hope there is time for corrections south or it doesnt develop at all. 

7 and 9 look pretty good, with 17 the high-risk megablizzard option!

This is the kind of set up that Id like to see by next weekend. Pert4 GEFS 12z (It gets blasted away... but nice to see a Scandi High)

No, no! 50ish miles further north, please 😁

I feel your pain......copious amounts of snow just to the north of us......really looking like the central belt will see next to nothing snow wise in the coming week........must be easily one of the worst locations in the uk for snow now these days.......

Tuesday is... very difficult. We have two systems merging while transiting the UK. I sense the models might be 'herding' towards one particular solution and are a little underspread. This is why the higher resolution detail which will become increasingly available tomorrow will be very useful. Scotland will obviously do well, particularly in the places that have already done well; but beyond that we have a weak warm/occlusion, frontogenesis of warm, cold and occluded fronts and then that all immediately followed by the next thing going into Thursday.

What I can say is if the system is as marginal as expected and doesn't become colder (again I have a gut feeling this might still happen) we could see a wierd distribution of rain/snow where there are hyper local differences within a few miles with rain/snow but not in the usual way where you have a warm airmass meeting a cold one; but wave like pockets of cold and warm air caused by highly complicated airmasses mixing in wierd ways and interacting rather strongly with the local topography (think local foehn effects warming things up by several degrees and yet 5 miles down the road its all covered in snow). 

Its an interesting enough situation that I'm tempted to do a snowrisk map for Tuesday. If I do I'll make it tomorrow evening if there is time to do that. 

It does look synoptically similar, unfortunately I can't remember this particular event. I'm assuming it wasn't spectacular up north. 

I just looked through photos from this event and we had snow in the end.

The smallest of adjustments to Friday's low will give very different outcomes..as has been said here already. One thing is for certain we will have rain and wind.

Not only that, but in marginal situations the intensity of the precipitation can be a key factor in forcing the freezing level towards the surface.  There’s also the reality that even half a degree difference can be critical, and I don’t think the models are that precise.

It dumped about 12–16 cm here. There was a notable difference in depth between the Bulbourne Valley and the surrounding hills. Some pics I took here:

It was an odd event, actually. I remember meeting friends for a pint in the evening on Saturday 9 December. It wasn’t even certain at that time whether we would get rain or snow here.

It also produced one of the best wet snowfalls I can remember in North Northants. Was a fantastic little event and the only real kind that now deliver in this neck of the woods.
