Slushy wet snow that struggles to accumulate... yay.

It's either a cold wet day, or a few hours with dirty, mucky slush everywhere as it appears now. 😐

Is a pity that any snow that falls will likely disappear quickly . 

Looks like there could be two pulses of snow, the initial one the best chance for the Midlands and may break up into N England during Thursday day and then a second burst which may only be snow  N England northwards and north of M62 by dawn on Friday before turning to rain slowly further north.

Arpege 12z even further south. London in with a chance.

GEFS 12Z has 4 runs which show accumulating snow in my patch. 😁

So, after the 12z runs we have Arpege now predicting snow for the northern part of Herts and northwards, albeit after a damp start.  

Alaro has firmed up on snow north of London, some of it quite heavy.

WRF has the rain-snow boundary north of Cambridge, but it’s moved south a little v the previous run.

ICON has the boundary slightly further north than WRF, with rain for Norfolk & Suffolk.  That seems to be partly down to a lower intensity of precipitation, which as Q has mentioned is critical when there needs to be cooling of the air.

UKMO has the snow in a similar zone to ICON, but again I am pretty sure the boundary has trended south.

So, 36-48 hours to go and still a lot of uncertainty across the swathe of the country north of the Thames-Severn Estuary line (aka M4 corridor…).

My guess right now for here would be some white stuff coming down but mostly wet on the ground.

There are probably a good few more ensemble members showing new snow depth here but I don’t really expect any snow cover as things stand.

An interesting divergence in the forecasts for this neck of the woods. The Met Office are going for a full day of snow tomorrow, whereas the BBC are going for a full day of rain and sleet. It shows how marginal this is likely to be, and it looks like I'm going to be right on the borderline.

Amber warning for the  Southern Pennines, Bradford down to Leek. Shows there is the potential for some very heavy falls in places. 

5 Miles from the amber area, probably prefer that as could be overreaction and closing schools in advanced on low ground inside the amber warning area.

I see that Edinburgh is under an official yellow warning for snow and ice between tomorrow evening and Friday afternoon.

I have no doubts though, that this is probably going to be yet another complete waste of time as these things generally never come to anything any more, especially here in the north Edinburgh where I am (the south of Edinburgh usually has a slightly better chance of getting something from that but it still wouldn't surprise me one bit there was very little or nothing at all there as well in the end).

I was watching Mark Vogan's video from yesterday (I haven't yet caught up with Gavin P.'s videos and I know that Gusty has also been doing a series of snow watch videos on his channel which I haven't yet caught up with), and the model output which Mark was showing at the time seemed to show that any snow coming up to Scotland would be more likely to just turn to rain before it gets here due to some milder air coming more into the mix, except for up over the hills and mountain.

That model output might have changed since then of course but based on that, the omens aren't exactly looking good for here as far as any snow or ice prospects are concerned.

I agree John. The top of Arthur's Seat and The Braids may turn white. The Pentlands definitely will. In most areas of the city it will be wet stuff.

Tomorrow looking even more marginal now, some sleet symbols appearing on Met Office app even at 200m and NMM model shows much lower accumulations.  Not really able to say to anyone  with certainty whether it will snow significantly here tomorrow.

It’s also why the various apps are so at odds with each other constantly as they use different models to spit out their info however many times per day

4c here with dewpoint around 3c. Can't see any snow falling here later despite most of the models suggesting that I will, if only for an hour or two before it turns back to rain.

I think most low level locations will only see rain or wet snow, however inland with elevation there could temporarily at least be some significant accumulations, especially in N England.

There may be some more showers up here until the front moves north bringing the milder air later on Friday. (Most of last night’s snow is still on the ground currently).

A very dumbed down forecast from Darren Bett looks like rain for most just snow on hills now.
