06z ECM is another stunner. The block just gets more and more robust as we approach T+144.

With uppers like that, at face value that little low will no doubt bring snow to some.

Looking interesting wintry weather-wise for those over the northern half of the UK, especially high ground. But for us south coasters it'll be the same old with cold rain and wind, which sounds depressing after having been pleasantly mild, bright and dry today.

12z GFS op show what can go wrong in the medium term, although it gives 5 days or so of colder weather over the UK (bit longer for the north) before the sinking HP ridge links up with the Azores HP and LP tracks over the top introducing milder air for all after a spell of transient snow for some.

I've not been taking detailed looks at the ens but I'd assume just from the scatter that it's been an option for a while, so presumably a case of the Op picking this solution this time. 

Will wait for the ens to see how well supported this is, along with ECM, UKMO and GEM runs.

Acts as a cautionary note I guess but hopefully an unlikely outcome as it stands, ignoring the law of sod of course.

12Z GEFS showing the balance has definitely swung towards a shorter cold spell for the south. Begins on the 19th and all over bar the shouting by early on the 23rd.

Some runs prolong the cold but both op and control follow each other to the mild breakdown (unlike the 06Z when both went cold).

Plenty of time to swing back yet but the UKMO looks pretty poor for cold too, with the cold air never really arriving in the south and the Atlantic ready to break through rapidly at T144.

On a more positive note the 12Z GEFS has the highest snow percentage yet for London at 35%.

With GFS sending everything south I thought it was encouraging to see ECM North,  blended solution please.

UKVs take on who gets lying snow from Monday/Tuesdays system FWIW (not a lot at that range!).  Other than that the run shows a fairly stereotypical shower distribution for the set up, unsurprisingly.

I don’t know of any model that is much good for lying snow. UKV can be good but a tad too conservative in my experience.  I miss EURO4!

Met O and ECM look like little chance of anything properly wintry affecting the south, the blocking all heads into the continent with heights deserting Greenland.
