Somewhat jealous lol Hope you get to enjoy it and that it's a decent amount.

No snow lying in the Lakes, either (apart from a few high peaks)

Parts of Scotland have had some but nothing spectacular.

Wednesday 12th - Friday 14th in the south

Those with some elevation will obviously fo better as it looks very marginal. 

Yes was -3 to -4 this morning and my conservatory was 0.7C before rising to 27.6 at pm so colder than the app min which happened other night. 🤪 It best to look outside now more accurately. 

Just looked at the radar/precip - you may want to wear your wellies!

Yes maybe, just light rain now and it actually feels slightly milder than earlier so the snow chances are gone I think.

At least the wind has dropped.

Exactly the same here bar half a degree colder.

If you trust the AROME, meteociel provides soundings for that model that go right down to sea level. They also do cross sections through the atmosphere (also avalible for GFS and WRF, but the AROME ones are better). I'll try and edit this comment and post a few but they are well worth it; and will show the warm nose very clearly.

Here is a cross section from Angelsy to the east coast going through York tommorow at around 9am.

You can see the pennines in black. You can see a substantial warm nose between 825hpa and 950hpa. Notably though the air isn't that warm, only about 1C , and the wet bulb will probably be around 0C. So this is one of those rare situations where snow is actually fairly likely in slightly positive 850hpa temps.

Here is the sounding for York at the same time:

Spoiler: It's snow but, its the wierdest profile you will ever see in the UK.

Right at the surface we have a temperature of about 0.8C, a dew point of -0.5C and a wet bulb of about 0C. The temperature quickly falls with height and looks to be subzero by less than 100m. However it then remains at 0C right up until about 350m, not dropping further. It does then drop a bit to around -1C at 500m and stays at more or less that level until around 1000m up. Then we see a big rise in the temperature, peaking at 0.5C at the 850hpa level before gradually going below freezing again.

The warm layer extends from about 1300m to 1600m which would be considered only just thick enough to melt snow under normal circumstances, but for most of that distance the temp is something like 0.2C so its not really going to melt.

My guess is this will appear as pretty much entirely snow , though some partial melting and riming of the snow flakes could occur so we might see slightly graupelly snowflakes. Snowpel?

Frame these soundings/cross sections. Itl be 10 years before we see something this wierd in the UK again.

You should look at the humidity too. 😉

Here's an actual sounding from Herstmonceux this morning.

You can see that the humidity drops like a stone above the cold Continental air, and that's why we've got the clear skies down here today - that air is seriously dry aloft!

Get the cold boundary layer in long enough and you'll eventually see the entire airmass below that dry zone become cold:

That was the sounding for the 28th February 2018, in the "Beast".

EDIT: And here's an animation of the cold air moving in during the "Beast" - you can see the full process of "Continentalisation", so to speak!

Its kinda like a 'mini tropopause'. Would be interesting to see the potential vorticity at that layer. Tbh I think the profile tommorow morning for N england is actually wierder and more unusual than 2018, albeit not actually producing any exciting weather on the surface. If there is actually precipitation tommorow (by no means certain) I'd expect to see alot of very wierd types we don't usually see in the UK.

Ah, you posted before my updated post made it through. If you look at the animation in the latter link which I added, you'll see it starts off in a very similar manner. If the Continental air feed is sustained, eventually everything below that dry layer becomes mixed, the whole lower airmass becomes cold, and then you have your classic cold spell. I've never looked at charts further north, so I don't know how rare or not it is up there - but down here that sort of thing is relatively common *if* you can get a proper Continental airmass.

It's also why in places like Yellowstone they get powder snow even at +7C - the cold wedge is very thick, and it's just the very lowest level which is warm, and even then the dewpoint is well below zero, hence the snow survives all the way down. I've heard you can even get snow at +10C, or 50F as they call it, out there. Of course here the sea does its best to ensure we seldom develop a Continental style airmass!

FWIW in "the Beast" we had a few hours of freezing rain as the Atlantic air moved back in. By then the cold layer was so dense, so thick, it took a while for it to be scrubbed away.

I think its a fairly common profile for the continent (either one) but its very unusual here. Also unlike the animation which you posted, we have a situation here where the whole temp profile is not moving in one direction, its getting colder lower down and warmer higher up. The main difference compared to 2018 is that the very cold air is only getting established at the same time that warmer air is also moving in at higher levels.

That being said tommorow early and late is looking pretty good. If you are away from the immediate coast and its earlier than 11pm or later than 6pm then showers could be turning sleety even to lower levels. And getting precip shouldn't be an issue, it will be fairly widespread; again late afternoon may be best for most central and southern parts while the morning might be best for the north.
