I genuinely think you guys are suffering more from UTDS (upper temperature dependency syndrome)! The colder air is far closer to the SE than you think it is, it was literally only 50 miles away from the SE on the GFS run WRF and that wasn't even the best model. And this is without evaporational cooling enhancement.

I don't want to jynx it because obviously we can still get downgrades, but if the SE does end up with snow early next week; remember me!

Having wasted all this money on Supercomputers and as they are clearly no better at forecasting the weather past T+10 days than they ever were, now they are stuck with them wouldn't it be better to ditch the ultra long range efforts and concentrate on improving short term weather precision on things like cloud cover and other more feasible aspirations?

Look here is a height profile showing why T850 is so misleading:

This is a line going west to east, left to right in Yorkshire on Monday. 

Do you see how weird that looks with a temperature inversion between T850 and T775?

There is a warm layer at the 850 level which is making everyone think its much warmer at lower levels than it actually is. 

If anything this is a profile you might expect in an absolute monster snow event because comparatively very warm air at ~700hpa-800hpa facilitates more snow crystal growth and aggregation and greater moisture storage.

Yes, an upgrade from chilly with rain, to cold with rain.

But wait, I hear you say, Q is all excited! Well, yes, you *can* get snow all the way up to zero 850s - I've seen it happen twice in the past 21 years - but it's darned rare here at least.

I can only speak about my local area on this, but here it only happens towards the end of a cold spell, when the boundary layer is thoroughly chilled and fronts "ride up" over the cold air. This happened frequently in the 80s and 90s, and gives the classic fine snow turning to think splodgy flakes [hence the old Kentish saying "when the snow is fine, there's more behind"], then it'll fizzle into drizzle as the front clears. The cold spell of 2005 - the last textbook easterly - was symptomatic of this, at the end it snowed right up until 850s reached zero, then turned to light drizzle, leaving behind a slowly thawing mass of snow. 

I can't remember this sort of thing happening *without* snow already on the ground, though, and the crucial thing to me is all the previous events started off with deep cold air aloft a few or several days prior, which is why I look for -10s before I get excited. I suspect it's due to the nearby sea (half a mile away to the NE, or 33 miles to the south) causing things to mix out a little. Even in the 80s we'd look for daytime highs in Calais of -2 or -3 to predict an ice day here. 

These current charts? I simply can't see that there's enough time for the boundary layer to cool enough - and become deep enough - to support snow down here. If I were a good way inland (think Reading) I might be more interested, but even then - I'd far rather see some proper deep cold air in place first. 

The other side of the coin is the complete lack of frosts in the forecast down here. For snow to not instantly melt on impact and to accumulate you need all sorts of things, and a frosty ground helps no end when temperatures are still above freezing.

I'd also mention that the ICON, at least the charts I can see, only has a rain or snow precip type field, it doesn't seem to show sleet in the way ECM does. As such it falls foul of the same thing that GFS has, i.e. a flake of snow in the rain shades the area as having snow.

Well the 12Z GFS joins ECM in giving some snow even for this part of the world on Tuesday. Certainly one to watch.

While the output has been frustrating so far in 2026, it certainly hasn't been boring!

Looking at GFS into next week, rather than a Greenland-centred high it is further east, around Iceland/Jan Mayen, which allows more mild air into the mix unlike the end of the 00Z run which had a proper NE wind. Let's see how it plays out from there... the blocking is stronger, just in the wrong place!

And I'd also argue that a frigid but very thin surface layer isn't quite what I'm talking about.

So for example look at the GFS12Z around noon for the midlands. T850 is around -1C, but T925 is -2C. What we seem to have is a tongue of warm air that starts at the 700hpa level and extends down to 850hpa. A T925 of -2C usually corresponds to a T850 of around -6C

At a glance I would say neither the block nor the Atlantic has given up and will continue trading blows for some time to come .  I would say in general the track of lows looks a bit further south over the next 10 days than was being modelled 24 hrs ago  …and longer term the block shows signs of eventually winning ( but which time it will also be spent ! )

Being inland, being further north, having some altitude all help enormously, essentially you have the climate we enjoyed in the 80s but have now lost. 

In the 80s we only needed to roll a double six, these days we need to roll 6s on five dice!

Personally as far south easterner I wouldn't mind a few hours of heaving falling snow, even if it was a brief slushfest and was swiftly rained away. Sadly not even that crumb looks likely down here. 

Generally I'd say wet, temps wobbling around the average for the next 10 days or so IMBY, with some tentative signs of maybe a couple of days of chillier weather early February although I suspect a continuation of average temps with rain is more likely. 

As other posters have mentioned the picture does improve (from a coldie POV) as you head north - looking at the GEFS the Aberdeen ens are interesting, at first glance there's a small milder cluster, with the majority firmly in the cold category from 25/25th Jan to 3rd/4th Feb where the scatter increases albeit still mostly below the LTA. There seems to be a reasonable chance of a few transient snow events after the weekend for quite a few areas, so not a boring outlook away from the far south maybe. 

Whether we get any breaks in the jet to allow something a touch more interesting for MBY is currently not looking likely but you never know. The charts are sometimes only a tweak away from being more resolutely interesting so some cause for optimism for me although it'll take a strong shift and cross model agreement before I take too much interest!

Really poor ensembles which show nasty LESS COLD temperatures throughout so any snow will not last.  Like what Retron is after is deep cold and proper powdery snow with sunshine and hard frosts.  LESS COLD temperatures bring dull, wet and sunless, so really prefer to get mild zonality back as least we get sunshine and frosts after LP move away.

Keep the analysis coming.

GFS 12z gives snow for many North of the M4 and especially those with a little elevation. 

GEM 12z does likewise 

UKV 15z is similar 

All at T+ 110 which starts to get us into the more sensible range.
