UKV turning up the thermostat again this weekend, but there is a risk of rain in the south west.

Rarely do you see the ensembles flat lining for two weeks with such good agreement. If the summer is even just average dry the Water Companies had better be readying to be blamed for the water shortages come August/September.

Warm or even very warm weather on the way this weekend? I expect the dry ground is a contributing factor.

In the longer term the GEFS is also favouring above average temperatures. If we do get the blowtorch I could imagine some VERY high temperatures resulting.

GFS OP 00Z; Current HP declining and being stretched NE-wards, by Sun 11th forming a new centre 1025mb Norway with warm SE-lies though a trough is lurking near SW Britain. HP gradually returns from Norway to a position N of Scotland Sat 17th 1030mb with ridge to the south covering Britain. The HP continues N-wards to Iceland while LP (much less extensive and shallower than yesterday's chart) gets to a position just off Cornwall 1005mb Fri 23rd.

ECM: like GFS but the 'trough near SW Britain' affects more of S England around Tue 12th before HP resumes as per GFS.

GEM: develops this trough further with a general fall in pressure over Britain continuing to end-of-run Sat 17th at which point it picks up the idea of a deep LP 965mb from yesterday's GFS.

GEFS: soon becoming warmer with a modest peak around Mon 12th, declining a little in the S but warmth maintained in the N, and possibly warmer again from Mon 19th though ens members do not agree on this at the latter date. Small splashes of rain from time to time (showery?), even these minimal in N & E.

ECM suggesting good chance of rain in the west Sunday/monday, then a brisk chilly easterly for the SE and east coasts.  Perfect for wildfires

Wow, GFS 6z is just a high pressure fest virtually from start to finish.

Here, I've recorded just 8mm of rain since 1st March. This is an exceptionally dry period.

Interestingly though, grass everywhere is still lush green, perhaps testament to the ground water levels after an extraordinary wet late Autumn and early winter.

Continuing unsettled through Tuesday on an easterly flow, then becoming more confined  to the SW on Wednesday. Mostly dry Thur/Fri apart from perhaps some showers along the south coast before rain risk increases in the SW quadrant of E&W generally for next weekend.

GFS keeps this weekend rain risk more to the SW and Wales, before more generally in the west on Monday. Mostly dry through the week before rain risk increases in the SW quadrant again for the weekend.

UKV continues to show it turning very warm this weekend and into early next week. Thundery showers look possible too.

WX temp chart shows all of continental Europe below norm in week 1, just Britain and even more so Scandinavia above, In week 2 there is a general warming with a special focus on France (getting close to England), and areas in Danube Basin and Ukraine. A large dry area around the North Sea in week 1, even larger in week 2 though moving northwards and some rain moving into SW Britain. Otherwise general rainfall across southern Europe.

GFS Op 00z: Current HP weakening, stretching towards Norway and by Mon 12th centred there with trough over N France affecting S England, with warmer SE-lies for the rest of Britain. HP centre soon moves back to Scotland and then drifts south to cover Britain 1025mb Sat 17th. LP from the Atlantic tries to move in but eventually only succeeds in moving north towards Iceland bringing in westerlies by Sat 24th.

ECM makes more of the trough over France and S England early next week before resuming the domination of HP as per GFS

GEM is like ECM though it places the trough further west, over W Ireland

ARPEGE last night was bringing in showers fairly widely for the S Coast late Sun into Mon, but this morning's chart only has them affecting S Devon Cornwall & the Channel Islands.

GEFS: becoming warm around Mon 12th and although dropping off a little, staying above norm to Sat 24th with good ens agreement. A few runs have occasional bursts of rain (highest chance towards the SW and around Tue 13th but don't hold your breath, even there).  Overall the picture is dry throughout.

No real sign of a notably warm air mass / plume pattern emerging, but we could still see very warm conditions at times.

Brian mentioned thundery showers above. Noticed when out earlier that slight but distictive creamy pink/purple look near horizon, which can hint at a more volitile period ahead.

A series of low pressure systems brought very unsettled weather during the last ten days of September 2024, with 150 to 200mm of rain falling in the wettest areas. Several counties in the Midlands recorded their wettest September on record with over three times the 1991- 2020 September average rainfall.

And on into November, for example:

I grant you, unusual for W Ireland not to be setting the high rainfall totals.

ICON 12z first out of the blocks this afternoon and shows a HUGE pattern change next week with a great big green blob (trough) slap bang over the UK. Cool and wet if that verifies. Totally different to anything we've seen in months.

ICON looks to make more of the changeable interlude early next week. But on the whole the deterministic are looking pretty solid with high pressure dominating.

In the parched south east Monday continues to look like the best chance for some rain.

GFS Op 00z;  Current HP first ridging to Norway and then becoming centred there Mon 12th 1025mb with shallow trough in the SW Approaches, not affecting NE areas. By Wed 14th the HP has moved back to Scotland 1030mb and dominates the rest of Britain, persisting to Mon 19th. It then gradually fades and LP works in from the Atlantic 995mb Irish Sea Wed 22nd. Pressure remains on the low side with another centre approaching from the west 995mb Sun 25th.

ECM; LP on Mon 12th extends a little further NE-wards but like GFS gives way to HP later in the week. This HP is less persistent and by Mon 19th has begun to track S-wards with a larger depression mid-Atlantic 990mb.

GEM; somewhere between the above two models to start with but on Mon 19th has the HP moving away N-wards with a disturbance approaching from Biscay.

GEFS; temps generally a couple of degrees above norm for the forecast period, even a little warmer on Mon 12th, with good ens agreement until Wed 21st when the ens members begin to spread out. Reasonable chance of some (showery?) rain on Mon 12th especially in the south, also appearing in some runs more generally from Wed 21st and dry in between;  but little rain in the far NE at any time.

With all the combined knowledge the met office is still unsure how that flabby low will affect the far SW on Sunday. I’ve got a cycling event and don’t fancy an embedded CB following me around all day.

GFS Op 00z; Hp taking a weekend break over Norway while England and Wales are affected by a trough from the south, showery in nature according to MetO rainfall charts, and not getting as far N as Scotland. HP then resumes centred over Scotland on Tue 13th and ridging to the south to affect all of Britain. This lasts to Tue 20th when it slips away SW-wards and by Thu 22nd a gentle W-ly regime is in place; eventually a shallow LP 995mb approaches NW Scotland on Mon 26th. For most of this period pressure remains on the low side over Europe.

ECM: similar to GFS. Pressure over Scotland rebuilds from the Atlantic rather than from Norway on the 13t - a distinction without a difference?

GEFS: temps very gradually dropping back to norm by Mon 26th from a modest peak in the S (4C above on Tue 12th), staying high for longer in Scotland with quite good ens agreement throughout. Small amounts of rain around Mon 12th in S & W, chances of more rain generally from Thu 22nd, otherwise dry.

Although Met Office app shows unbroken sun for Saturday it has partly clouded over  in London with a cold NE breeze off the North Sea  currently 19 degrees  going forward it is meant to warm up in the next two days but I have yet to be convinced
