As alluded by other there are sign of higher pressure, particularly for the south as we move towards the end of the month. No blow torch, no depth of cold. Seasonal
GFS onboard, ECM not awful but a little wobble. Things are disrupted in the usual flow and we might be on the verge of a decent blocked cold spell. GFS no doubt will drop the idea in the 6z!

Only 8 days until the parallel run takes over as the main run so I'll just ignore the old one now
Quite interesting Sea surface chart for North Atlantic Not sure why there is a very cold area from Greenland towards Faroeshttps://www.weatheronline.co.uk/cgi-bin/expertcharts?LANG=en&MENU=0000000000&CONT=euro&MODELL=sst&MODELLTYP=3&BASE=-&VAR=2&HH=0&ARCHIV=0&ZOOM=0&PERIOD=&WMO=Is this something worth keeping an eye on ?

The bad thing about SST's like that is that cold winds will be modified by the warm ocean. On the plus side, though, if we can get air that's cold enough, the high SST's will allow serious shower convection with copious amounts of snow!

I’m looking forward to the ensemble suite running on the new version; nice as some of the charts emerging from the new version are (from a cold weather perspective) it’s impossible to make any judgment without the wider picture.
That block on GFS is huge and beginning to get some influence
It's in a funny position, with energy going over the top of it. Not a great block to bring us cold at this time of year (ideally it'd move around 1000 westwards and 500 miles north!
And you get your wish a little bit further on in the run Saint. It's a humdinger for this early in the season. I spy a Murr Sausage 😂😂
I’ve been out watching England. Can someone put a very brief summary

Heights rising to our North and East and then building from Scandi to Greenland bring a cold Easterly and risk of snow showers.

GFSP isn't a million miles away in the egernal evolution, eaither.
Yep that's what it looks like to me, even if it does set up per the GFS 12z, which I highly doubt anyway, there will be a lack of cold air to tap into and we will get drizzly 5c days and frost free nights.
Fun trends continue this evening. Op & control favour some sort of anticyclone to our N/Nw/NE (delete accordingly) ECM not in disagreement in its closing timeframe either

GFS ens have decent support for some sort of pressure rise to the North East or just over the UK and ECM op at least agrees at the T240 point.
I suspect though 850s of -7c or higher would for the most part bring cold rain and a fair bit of dank weather but encouraging setup at least and increases the possibility of getting cold enough air in for some wintry stuff.

Codge are you there?!!
Yes, I'd say more likely than Moomin's optimistic summary
