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

Hear hear! It's roller-coaster time, chaps.

 

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.

Yes all looks very blocky at the moment.

dont worry, the blocky charts will soon evaporate come winter proper only to miraculously re-appear during late spring.

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

Yes I think that is the weather headline during the second half of the week.

Yes blocky charts do tend to appear more frequently at this time of year.

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

Always love this time of year. Charts out earlier and you know winter is knocking on the door.

Same here personally this time of year signals the start of when I take a little more notice of the charts.

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

1) Everyone being in the UIA discussing Brexit as that's more topical.
2) Perhaps some of us are already experiencing Autumn fatigue with the recent rains, especially as both ECM and GFS looks depressing with a dartboard-style low slap bang over the UK after the weekend.

That and in terms of winter potential it is a bit far away, early and tenuous. Worth watching though out of casual interest,

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.

We live in a very active part of the North Atlantic indeed. It reduces the size and extent and duration of low temperatures and winter snow, and it reduces the length of very warm and hot sunny weather.

Our weather breaks down often after we get some either cold and wintry weather or get dry and sunny weather. Brief and also longer lasting Unsettled and wet weather with mild winter weather or cool chilly and cloudy conditions in summer's. It used to be colder and snowier and frostier both day and night, but nowadays we often see above average temperatures both day and night as our Planet Earth is entered into a warm human induced Global Warming Phase. Long fetch of warm air SW winds over longer distances- reduce the chances for the UK to be affected by cold plunges and spells, living on the NW Europe part fully exposed to Atlantic mildness.

Little change to this since yesterday, so I've cheated and done a quote. But

  • 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
