Another very interesting GFS 0z Op. A month too early but we take what we can get.

 Interesting too and glad this horrible HP that now on top is giving overcast weather which modelled previously to last to mid Nov GOD FORBID is a hell to put up but thankfully the models again dropping this and kick this HP up northward to allow lot of sunshine and frosts.

If they are right this really totally opposite to LRF going for very mild, stormy wet November.  It more like Autumn 1995 this time with short lived Autumnal weather that just passed by recently to winter straight away.

Definitely possible,  November could also be the first below average cet month this year.

It been like this this 2020s decade recently and last recent snow was as far as back in 1995.  To me personally i think winter chances had been moved from typical peak Jan to Feb to now mid November to mid Jan with Spring coming early.   My main focus on the models viewing is to see the HP to leave so to get the sun back and get first frosts too.  Snow if come is a bonus here.

Looks like some chilly and calm weather through the first third of November before more unsettled weather returns.

FAX - A front drifting first east then south but being squeezed out of existence between centres of high pressure, first 1032 mb Holland today and then 1042mb SW Scotland Mon 2nd, the latter having come in from the Atlantic and moving slowly NE-wards.

GFS Op 00z - by Thu 5th the latter HP has moved on to the Faeroes 1035mb with E-lies for England. It slowly declines over the following week with LP 995mb Scandinavia  becoming the dominant influence with light N-lies. By Sat 14th a new LP 985mb  Faeroes appears in the circulation of the main Scandinavian LP and deepens 980mb as it moves into the N Sea Sun 15th with N-ly gales for Britain*.

ECM - diverges sharply from GFS after Sat 7th; the HP has declined but the Scandinavian influence is not there. Instead pressure drops quickly over Iceland and the Atlantic, so on Mon 9th there is a weak ridge of HP down the eastern N Sea and a trough of W Ireland with S-lies, not N-lies, for Britain. All this is swept away as the LP near Iceland gathers strength and moves E-wards, by Sat 14th pressure has risen behind it 1030mb N Sea and SE-lies cover Britain.

AIFS - London, maxima dropping from ca 13C now to 8C Wed 11th before rising again; often cloudy but virtually no rain. Edinburgh, maxima also ca 13C now bur a swifter drop to 7-9C where it stays until warming from Wed 11th; dry apart from a little rain either side of a cold night Wed 11th.

GEFS - mean temp first a couple of degrees above then below norm in the period to Thu 5th after which close to norm in the middle of well grouped ens members  (control and op among the coldest, as much as 6C below norm at times). Chances of rain increase from Sat 7th, in quite a number of runs from Wed 11th. Snow row figures lifting off zero into low single figures for Scotland but even a couple of 1's on the south coast.

A interesting period of model disagreement

      

* not as dramatic as some of last night's charts which brought this LP down to the Channel as a deep low with a circulation of very cold air for the season.

Most importantly this morning the SSW is still on for about 5th to 10th November. So we have a chance as we go into winter for something interesting

Lol GFS 6z , the GFS is desperate to get the party started early.

Great to see so much high pressure in the ECM. Hopefully we can tap into a more southerly flow

GFS like a dog with a bone. The 06Z again has very cold air sinking south and south west, eventually covering most of Europe and the Atlantic......a bit early but I'd be happy with that

Other models seem unmoved, but even they have cool High Pressure....maybe frost & fog becoming prevelant?

I'm amused that the subheading for this topic still reads "More heatwaves on the way this summer?" I'm fairly confident that the answer to that is "no".

There are the GEFS 06Z pressure patterns for 8 November. The 12Z ECMS / GEFS / MOGREPS-G updates should be interesting.

Looks like it could be a false dawn in terms of cold weather. It could actually turn very mild during the middle third of November if the high sinks as now looks likely.

FAX - current HP 1034 mb Holland giving way to new HP settling 1040+mb Scotland from Mon 2nd onwards, with a weakening front drifting S-wards between the two. Very little action in the N Atlantic/Europe generally; usual LPs passing Greenland and Iceland, and a local storm 1002mb Sicily Tue 3rd.

GFS Op 00z - the HP over Scotland hangs on for the next fortnight despite Atlantic troughs threatening the west Tue 10th; eventually it sinks southwards and westerlies take over on Sun 15th.

ECM - like GFS for the next week, to Sun 8th. Then this model shows pressure dropping SW of Ireland and eventually a depression running along the Channel 995mb Wed 11th followed first by a rise of pressure but another trough forms to the SW Sun 15th

AIFS - London, maxima around 10C, a little warmer at first and after Fri 13th; occasional splashes of rain, rather more Wed 11th (but still not a lot). Edinburgh, maxima also around 10C and mainly dry for the next fortnight but up to 15C with rain from Fri 13th.

GEFS - mean temp above norm for a couple of days, then close to or a little below norm and dry to Tue 10th, all closely supported by ens members. Then the spread of ens members opens out to +/-7C but mean temp stays near norm and chances of rain increase esp in the west.

Still looking for the wet and stormy 'El Nino late autumn' - not much time left for it to turn up.

The Met Office still going for it, but confidence at that distance is low of course.

https://weather.metoffice.gov.uk/forecast/gcn243hge#?date=2026-11-01 

"During the second half of November, there is an increasing chance of changeable or more unsettled conditions developing, which would mean spells of rain and the potential for strong winds at times. The extent and location of the wettest and/or windiest areas are very uncertain at this range, with the wettest and windiest weather probably towards the north and west, but there are hints that overall the south may be wetter than normal whilst the northwest is drier than normal, suggesting the possibility that areas of low pressure may be steered further south than normal. Overall, temperatures will probably be near or a little above normal for the time of year."

What are the hints?

Perhaps it is just the way it is written but this seems somewhat contradictory: “the wettest and windiest weather probably towards the north and west, but there are hints that overall the south may be wetter than normal whilst the northwest is drier than normal”

Is that suggesting that the NW is likely to be wetter than normal but there is a chance that overall it could drier than normal? Perhaps it may be as wet as normal? 

The current model output suggests a predominantly anticylonic outlook but with specific detail varying between models.

The way I read it is that rain looks to be evenly distributed across the UK, but with slightly more in the NW, but because of even distribution this means the South will also be wet.

They're terribly written most of the time. And always slow to a pattern change.

Anyway,  the SSW is still on for about 8th Nov,  and then hopefully December 2010 redux.

1. They're terribly written most of the time. And always slow to a pattern change.

2. Anyway,  the SSW is still on for about 8th Nov,  and then hopefully 3. December 2010 redux.

1. IMO, they're one of the most useful parts of the Met Office website. Even if they only flag possible deviations from climatology, with an indication of the strength of the signal, they're worthwhile. Therefore, I hope they continue, although I agree that at times they could be written better.

2. It's very interesting meteorologically, but with every passing SSW, the link between these events and significant cold outbreaks in the UK seems more and more tenuous to me.

3. As far as I can recall, there was no SSW, but the event was picked up about a month ahead and consistently forecast. Since then, I don't think there has been any significant improvement in the 2–4-week range, although I'll stand corrected on that. That in itself raises questions about the value of AI models at these longer ranges, because you would expect to start seeing improvements by now.

I think  without one this winter especially early on we'd have virtually zero chance, with this one maybe a 30% chance of a proper cold spell. January 2013 made me a believer, an SSW in early Jan and 2 or 3 weeks later a proper cold and snowy spell . Textbook.
