Decent from the 18z 

JFF of course 

18z GEFS doesn't look too bad at all  , block holds well with cold air never far away 

I’m surprised there’s not more commenting on the output to be honest, it seems like most here just post and whinge in the UIA thread and rarely contribute here, bizzare for a weather forum.

I think going forward the signal for a cold but mainly dry output up to around day ten are fairly strong, I also think we’ll see heights retrogressing towards Iceland/Greenland allowing for much colder uppers to envelop us around the last few days of the month and then into the start of next month. What happens next is certainly intriguing with regards to continuing wave activity disrupting the Strat leading to further blocking at high latitudes, the question is will a strengthening QBO see further blocking towards EuroAsia as heights pull back eastwards.

Considering the output strangely quiet 

why not all records are made to be broken, amazing Synoptics and a potentially memorable spell

Sorry am I missing something?

looks like a dry chilly spell next week followed by a gradual return to average temperatures and a little rain;

More like a showery chilly spell down here, with a 50/50 chance of either turning colder in the last week of the month or milder again.

(850s are pretty useless in easterlies, as you know.)

EDIT: The ECM ensembles are similar.

Operational and control are cold but caution is needed as there are more milder outcomes showing compared with yesterday after the initial mid week tame easterly.

Remember the old addage...if it can go wrong it will....

Less support than an extended cold spell this morning. Too early to make a call though.

ECM 192 hours (0z)

Great synoptics. We may need to play the waiting game for deep cold though.

The real action as we head towards the end of the month is certainly a little further to our east on the model output this morning but things are certainly starting off on an interesting note this winter.  It certainly wouldn't need much to tap into this early season cold to our east.  Perhaps it marks the start of a new frostier relationship with our European neighbours to the east! Here is the GEM at T240.

No more than chilly in the reliable time frame, as I pointed out a few days ago, and although the blue colours get to us by the end of the month, that's still FI.

All roads continue to point to a cold and possibly wintry nirvana towards the months end/early December, it’s still uncertain just whereabouts the block will end up at its final destination but colder conditions are now in the bag IMO, how cold and wintry is yet to be confirmed. Great model watching for sure.

Indeed . And interesting how the BBC have not picked up on this...? In their monthly outlook.  Fro. 26th November then never even mention cold or frost let alone snow.

ECM and UKMO extended are reasonably close this morning with both going for more of a southeasterly

GFS and GEM are also reasonably close both go for an easterly

Looking at the latest Met Office fax charts:  http://www.sailingweatheronline.com/old/bracknell_all_highres.htm what a waste of what would be the perfect set up in late January or into February. What's the betting that come deep winter we'll never get to experience those synoptics again.

It is not a waste if the PV can remain disrupted for the next few weeks.

It is a waste, if the PV regroups in its normal location and we end up with a positive NAO winter.
