This morning's GFS ahows the HP for this week not standing up to a push from the Atlantic, one depression moving across around 1 Nov, then a really disturbed (cool and wet) week from the 4th. HP over Scandi not really evident until then end of the run so reserve judgement on that. GEFS ens agree with this and to an unusual extent with each other, though not as cold as synoptics suggest.


GFS puts the cold and wet firmly across S Britain, ECM (from yesterday, and at the end of its run) further north.

Horrendous. I thought we were passed the wettest period. Parallels with the 2013/4 winter

Officially cold weather watch starts with the GFS 00z tomorrow as the clocks go back. Good luck everyone if you want cold,mild,wet,snow wind or fog. Just remember don’t get upset, or you will be disappointed. Enjoy the input from everyone and don’t be too critical

And I'd like to express my thanks to DEW for keeping this thread ticking over with intelligent and concise summaries of the outlook for the past few weeks. My model watching is limited to the MetO Fax Charts and a glance at the GEFS, but it's reassuring that my tentative ideas about what is being shown are backed up by someone more knowledgeable than myself.


The GEFS appears to be in agreement up to the 2nd Nov, after which the prospects are much less clear.

ECM t+ 10 days showing the potential for something wintry to develop. Could easily be very wet too. GFS / GEFS generally looks pretty unsettled to me with further flooding likely. A few of the runs appear to have the Atlantic going into maximum overdrive later on, but at this stage there is a good deal of interest.

Could this be coming into play this winter (as it appeared to in 2010-11)?

I’m going to enjoy the next few dry days, beyond that it could turn very wet again with localised flooding likely.

I agree the main concern currently is the amount of rain that looks likely to fall.

After a few dry days at the beginning of this week, an 'ordinary looking' LP moves in to the NW, with rain for everyone. A brief let-up in the south, then both GFS0z and ECM12z (Sun) are agreed on putting a deeper LP firmly in place across Britain for the whole of the week starting 4 Nov, and the jet stream forecast matches this with a strong jet close to S England. GEFS is briefly above average for the rest of this week, then consistently and widely a bit below average for the whole of next week. No real outliers until the end of the run, when one (don't get too excited!) even produces a snow row value of 1 for Brighton, of all places, on the 12th.


The end of the GFS run, around the 12th, and always subject to change, has a NE-ly flow across England with HP to the NW. This could indeed be cold, seeing the way that the blue colours are stacking up across E Europe by then http://www.wxmaps.org/pix/temp4

Hmm, Page 42 date Oct. 28th 2019.


The years that end with 08,09 seem to favour our Normal Autumn Weather Sequences.


Will this Locked in Low Pressure pattern happen as forecasted over the UK, I think it is good to check the forecast models at the T72 to T192 range.


What matters is how long it rains- how heavy and how large an area get’s hmm.  Breaks in these wet and windy spells are a feature we know a lot- dry spells with lighter winds.  They are good.


Under the 72-96 hr time frame it is a good idea to see where we are position in the Jetsream and if it settles down we can see some interest that points us at dry and nice weather.  If it gets windy and wet it will be or not and be changed as we get closer to those days- no point saying we are confident in cold and dry condictions returning to the UK.


Page 42.  Nice model output today but it does not appear to show much in the way of cold and wintry weather.


Climate is warming up, Scotland and N Ireland and North England still often gets some Winter frost, ice and snow, November to March, but the SE and South UK including S Central England and Wales, together with the West and North through the year, they sometimes get more rain than London and S SE England, where some longer dry fine spells without much heavy rain is seen every year.

The North Atlantic Sea often gets some much Colder Wintry conditions from November to March Months, and Mild SW and South winds tend to be more frequent over the East and SE of North Atlantic Sea, as the Azores High tends to stay in charge. 

With this warmth and heat, the Central and South UK has become mostly free of snow and frost.

  • next week's unsettled spell likely to start sun 3rd rather than Mon 4th

  • end of GFS run develops Scandi high around the 12th with ridge to northern areas and a drier spell, matched by next week's powerful jet stream breaking up and meandering

Looking at the GEFS, the first 10 days of November look pretty wet and unsettled.

The beginning of November now starting to firm up on a wet setup, going to be some flooding issues for sure. Slight hints of something a little different mid month?
