WX temp charts show a warm Europe for the next two weeks, extra hot around the Baltic, cooler patches for N Scotland up to Iceland, also the Alps, and definitely cold for N Russia. Very dry in week 1 for Scandinavia with rain around the fringes (incl W Britain), this very dry area expanding W-wards in week 2 to include Britain (except maybe the SE) and heavy rain France / Alps / Balkans.

GFS Op - shallow trough moving E across Britain tomorrow, followed by HP from the SW, its centre slowly moving E-wards. By Wed 26th it's 1020mb Norway with  LP having spread N from France to Britain 1000mb Irish Sea Thu 27th. HP re-establishes as a SW-NE ridge across Scotland which lasts through to Sun 7th but with continental LP never far away from SE England and NE-lies through the Channel.

ECM - like GFS at first but the LP Thu 27th moves first up the N Sea and then settles at 995mb W Scotland Sat 29th having imported cold air from Greenland to create an unseasonably cold trough covering Britain for that weekend.

GEM - close to GFS output (LP 27th over S England but soon replaced by HP)

GEFS - warm to Wed 27th with good ens agreement, then dropping back to norm with the usual spread developing. Rain most likely around 28th (big totals in SW, not so much in NE), mainly dry before 27th, intermittent rain in various runs after.

Laughable HLB on the ECM this morning.  Pretty much zero chance of it happening.  ECM has been terrible in the 168h/240h zone. Cannon fodder model atm.

Much better than the ECM though, has no HLB so HP can build in from the south. 

Edit. HLB turns up and it goes all Day After Tomorrow.

Interesting little upgrade on the GEFS 6z. Quite a few more ensembles keeping the warmth until Friday including the Control.  Hopefully the start of something.

Those 25s are from the new automated system, which has been within a degree of reality - it's been superb so far and has completely outclassed the GFS (which has 17/22/22/24/17 instead). Bear in mind too that's 25C with winds from the North Sea, which is presently 16C off the coast of Sheppey!

As you'd expect, if you look inland (e.g. Heathrow), you'll see 27s and 28s. Not scorching, no, and right on the borderline of "hot" (which is 6C or more above average). I would have said "very warm", hence my comments on the MetO text forecast.

It's interesting, as an aside, how sloppy they've become with their terms. It's perhaps unsurprising that the official definitions of "warm", "hot", "cold" etc aren't easy to find on their site...

In London 25C is only a couple of degrees above average so would probably not be viewed in the same way. Still, this is diverging away from the models now so mods could move this to a more appropriate thread if discussion continues?

Both GFS and GEM show a quickish return to HP after Wednesday's breakdown. 

UKV has 28/29c Monday 29/30c Tuesday 

ARPEGE has 31c Monday

I think we have been led up the garden path again, as it looks like a blink-and-you'll-miss-it waft of warmth.

Although having looked at the GEFS posted above, the operational run is one of the worst of the bunch for warm and settled weather.

GFS for Sun 7th (T +384) has a northerly plunge for Cornwall and a southerly plume for Greenland! Crazy weather, just hope it doesn't verify - and at the rate that the charts are flip-flopping, the eventual situation could be quite different.

Some very warm runs on the 12Z GEFS. Pert 2 for instance brings the 20C isotherm up to the south coast.

Our Local Authority has put out a Yellow Met Office Health-Heat warning, that runs from Monday until 6pm Thursday.  I believe that triggers at 27c, so the Met O are obviously seeing some summer weather next week.

Nice upgrades this morning for extending the warmth through next week. GEM,  GFS and Arpege all have 30c at some point.👍

No significant breakdown being shown now as well. Good news for Summer fans. 🤞it holds.

Its nice to see the output continue to look more summery albeit not totally settled.

Anyway, that’s off topic. What isn’t off topic is the charts look ok again this morning. Being picky they are still nowhere near as high-dominated or hot and humid as I would like, but this will do for starters

It is a reminder to community health care workers and neighbours to make sure the elderly are well hydrated and are ok between social care visits. You will often see elderly with their heating on full even when temps outside are above 25 degrees. Might seem daft but elerdly who cannot move around the house independently still feel cold regardless how warm it is outside.

What we see as a period of summery weather, can be a killer for some. Remember to check your on your elderly neighbours, even when we do not think the weather is extreme for us 😊

WX charts scale back the warmth in Europe in week 2, especially around the Baltic. Britain grades from warm in the south to cool in the north; continental Europe stays generally warm; coastal Norway and Iceland rather cold. Dry from Britain to the Baltic in week 1 with rain in Iceland and in S Europe; in week 2 the latter dies out while the former extends S-wards to Scotland and Norway.

GFS Op - HP in from the west to start the week, but LP from France links up with a deeper one near Iceland so all of Britain is under a broad trough by Fri 28th. HP, again from the SW, re-establishes for next weekend, but sinks S-wards by Wed 3rd to usher in a spell of zonal weather with W-ly winds, later NW-ly, fine for S Britain. less settled in the N.

ECM - the trough on Fri 28th is more concentrated in the N (990mb Malin) and then drifts S-wards, filling, so although pressure rises for next weekend, it's more by default and described better as shallow LP.

GEM - generates the deep LP as per ECM but a day earlier , but then moves it quickly NE so HP soon back and firmly in control

GEFS - warm until Thu 27th and then temp dropping back to norm with general ens agreement. From Mon 1st mean is slightly above norm but with plenty of variation, in particular op & control going in opposite directions. Not much rain in the S & E but a few runs have big peaks. In the NW, more continual from Thu 27th but relatively small amounts.

ECM seems to me to be somewhat out of kilter with GFS and UKMO this morning. ECM wants to keep LP over or just to the SW of the UK whereas the latter two models have it placed further north with less by way of nothern blocking. We shall see which of them turns out to be nearest the mark.
