Nah. GFS UKMO and ECMWF from 96,120,144hrs not that interesting for the UK at all.

And beyond that GFS has no idea at all- no cold Northerly flow being shown.

I guess the warmer and drier weather will return, but as it does- so will more wet and windy and cool weather or mild SW winds and heavy rain or showers mixed with sunnier spells.

Nothing special at all, it gets drier by Monday or even by Sunday I believe. 

Then Low Pressure could move in by the 24th and 25th October in it.

So diffficult for the UK to get colder weather in October, milder weather again forecasted by UKMO, GFS and ECMWF Models by Tuesday the 22nd October etc etc..

.

I'm beginning to sense that the remainder of October may be on the unsettled side, and notwithstanding the large amount of scatter in these central England ensembles. 

I do note that the precipitation spikes pick up again from 25th, so a resumption of the wetter and  unsettled theme is a distinct possibility at this stage, after somewhat of a respite later this week and early next.

Edit - In recent Octobers we've seen quite a few late plumey events.  Todays 12z GFS again plays around with this idea: one to watch and see if it is one that is dropped for a cold plunge as was showing on recent runs. 12z uppers for Halloween shown below:

Good evening to all.

There appears to be a mixed signal from ECMWF model 12z that areas of Low Pressure and cool conditions have good chance of influencing UK NE Atlantic and North Europe Airmass set up.  
It is looking chilly but 23rd October showing up as less cool..

The GFS, UKMO and ECMWF are going to experience a few twists and turns in the next 5 days.

All to play for.  Cold air in Greenland and Arctic and Norwegian Sea North Atlantic and North Europe still looks quite potent and organised player in all this.

All change this morning. Next week's forecast HP only hanging on by the skin of its teeth, and sited to the east of the UK (NI/NW Scotland not getting much of a look in). ECM shows and early breakdown with local LP back by the end of the week, GFS a more comprehensive breakdown later with cold air from the NW. Only 3 or 4 of the GEFS runs have any sign of yesterday's northeasterlies. Big variations in ens temps

ECM at the end of the run comes true I am going to start selling plans on Ark building!

I’m looking at selling my boat..... maybe I’ll wait a week or so....

I see the the GFS models have backed off from that Northerly cold snap during the final week of month?!

FFS

The UKMO, GFS 12z runs today keep the UK under High Pressure for much of Next Week, very quiet week of Autumn weather expected.

The Norwegian Sea NE Atlantic to our North and NE, NNE Europe and Iceland plus Greenland and also NW Atlantic get some cold winter weather, but by Thursday and Friday the NW and North Atlantic see further West to East Moving Jetstream energy- with Low Pressure systems Undercutting the Greenland high, then undercut the SW side of the Cold Pool to our North and NE Lol.

The Blowtorch High is being shown by the ECMWF 12z, giving the UK nothing much- the NW Atlantic at 24-24-72-96 hrs is being shown to get only Scotland and NE Ireland some of the tip of the cold arctic air, but for much of the UK on Sunday at T96 hmm, cool and showery regime is being shown.

This model is agreed with the GFS and UKMO, but the ICON brings the Cold Arctic Northerly in by Thursday and Friday the 24th and 25th October et all.

So- on Wednesday- with 12z ECMWF run being awaited, we see fine settled high pressure over the UK, NE Europe get cold arctic air this coming Weekend, with a few days break then another NE Europe cold plunge from Wednesday onwards aka the 23rd Oct. 2019.

Low Pressure over the NW Atlantic next week as being shown at T96, for this Sunday 12z runs, 20th Oct., a large WAA wedge of air associated with a Deep NW Atlantic Low.  This is shown to cross NE Atlantic and push from the NW and North Atlantic to Southwest and SE of North and NE Europe (away from the UK).

The ECMWF 12z is not showing a mild SW flow in NW Atlantic but actually a cold arctic Plunge for North Atlantic- with massive blocking high- Greenland high, but less cold for West and SW side of Greenland next week. Iceland, Eastern Greenland and Svalbard plus Norwegian Sea and NE Europe seeing very cold spell indeed- is forecasted.

Similar sort of pattern to yesterday, but with GFS being more bullish about HP over the UK, stronger and continuing longer, though there's a close brush with a depression in the NW mid/late next week. ECM more hesitant about setting up an HP cell, bit indications are there. Most GEFS runs have temps at or slightly above average, and rainfall low, especially in the op and control runs.

One cautionary note - Hagibis has sent the jet stream into wild meanderings, and according to Weather for thee Week Ahead on BBC last night, this is badly handled by computer models. They were not really offering any forecast for as much as a week ahead. https://max.nwstatic.co.uk/gfsimages/gfs.20191018/00/159/hgt300.png 

Trend for HP to be in control in 9-10 days with a nice blast of cold to the NE.

Would be great in a month let’s hope it’s a repeating pattern

Ten days is a long time in weather! Latest GFS charts show breakdown then with LP from SW.

High pressure generally present for a week or so after current LP fills and moves away in the next few days. GFS shows it as the fragile* tail ends of ridges, first from SW then from NW.  ECM more positive on a definite HP centre, FAX and GEFS show LP grazing the NW with rain for Scotland even in the middle of next week. S Britain notably dry until beginning of Nov

GEFS temps about average except that the op run is a notable cold outlier, as much as 5C below normal for several days

* Fragile in the sense that there are quite deep LPs on either side which could easily expand or move so as to displace the ridge

I see Iceland is about to get its first proper winter blast with bitter northerly winds and ice days with heavy snow showers in the north of the island. 

Quite a strong blocking theme over Greenland and the mid Atlantic which could give us some seasonal weather - however the Arctic flow looks likely to miss us with high pressure nudging in from the SE.

Yes, when looking at the FAX charts for next Tuesday and Wednesday I was struck by the big HP area extending from north of Greenland to south of Newfoundland.  I don't remember seeing such a large HP in that location very often.

Definitely the chance of something a bit chillier towards next weekend. 

Really interesting pressure pattern to our NW.
