All looks very nondescript now. Certainly no signal for anything cold. PV looks to be getting more organised as you would expect.  Not massively unsettled yet though.

WX charts - continuing yesterday's theme. Week 1 shows mild air flooding NE-wards across France up to the Baltic (but missing Scotland) while the cold air in the east is pushed SE-wards to the Balkans and Turkey. The mild air stalls in week 2 and something much colder firms up the freezing air mass over Russia, but not yet moving W-wards. Pptn for Atlantic coastal countries in both weeks, focused on Britain in week 1 and on Portugal in week 2. Also over Turkey week 1 moving west to the Med in week 2.

GFS Op 0z - current NW-lies withdrawing with parent LP to Norway as storm Bert approaches and deepens ever more; tomorrow FAX shows 937mb about 250miles W of Ireland with SW gales and more for Britain with fronts taking their time to cross the country over the weekend. By Tue 26th Bert is in the northern N Sea moving away but trailing a secondary 995mb Wales Wed 27th (new feature). Pressure rises behind this but drifts slowly E-wards to Germany with W Britain affected by Atlantic troughs from Tue 3rd. Eventually these troughs make progress NW-wards and the HP sinks S-wards to leave a standard W-ly zonal flow Sat 7th between 965mb Faeroes and 1025mb Spain (penetrating quite deeply into Russia contrary to WX above)

ECM - no secondary Wed 27th, pressure rises more quickly, but also subsides more quickly with trough extending S from Faeroes  to S England on Mon 2nd with weak N-lies.

GEM - like GFS but troughs after Tue 3rd closer to W Britain

GEFS - very mild for a couple of days as Bert moves through, dropping to just below norm around Tue 26th, then near norm or a little above to Sun 8th with moderately good agreement from ens members throughout. Rain quite likely at any time, esp in SW,  perhaps a brief dry slot Fri 29th

Don’t know if it’s just me being hopeful but I feel it wouldn’t take much for a significant cold spell to develop through December based on how amplified everything seems to be despite Burt spoiling the party.

Before anyone asks, the GFS 06Z banger has some support from its own ensemble set.
I’d put the solution at 3% chance of verifying and thats being generous, but at the very least it’s entertaining.

Got to laugh at the GFS 6z Op. 

Seems rather out of step with preceding ens efforts although I guess the potential was there on some of yesterdays ops, just the Atlantic was modelled to have too much life in it. 

In the more reliable range that little feature that GFS spins up for next Tuesday/Wednesday needs watching IMO - quite a tight looking LP and again wouldn't take much to upgrade it from a bit windy as it currently is, to something more disruptive. Currently only the GFS that really develops it, with the UKM showing something not too dissimilar so may well disappear anyway but again potential is there.

Not really seeing as we live on the Atlantic's doorstep. Remember many a night going to bed with Snow coming down to wake up to a slushy mess and it pouring down with rain. And that was the 80's

As for the 6z GFS, lovely synoptics but just not cold enough... I'd be looking for -10 850s as per usual in a "winds off the North Sea" scenario.

ICON6Z is also a synoptic upgrade.
We'd be salivating at these charts had we not just had a week of cold. Its the wintryest November since 2010 I think so far.
