That's not true, I acknowledged there were some forecasts showing 40C (exceptional by any definition) but struggled to find any excitement for it because its all becoming desensitising. I never implied that exceptional weather was not on the cards.

Even if we break an all time record next week (which looks a possibility now) it will probably be broken again in a couple of years anyway. Its a comment on how rapid things are warming really.

Anyway speaking of extreme, ARPEGE now has a full 41C contour visible on the Wednesday.

Those of a nervous disposition may not want to look at the Arpege 0z

By far the hottest run so far.

Max temps

Monday 35c

Tuesday 41c

Wednesday 42c

On Wednesday night it's still 31c at 3am in some parts of the Southwest!

I think it's clear now that the excessive heat will reach as far north as Manchester across to York

North of that, a summer mix of fresh SW winds and sunny spells and showers, just like the Spring & Summer so far. We saw a 25 C in Edinburgh in the May hot spell. I suspect Glasgow & Edinburgh may see a 25 C again next week.

I’ve also noticed that as the UK temperature gets increased, the max in France seems to drop, from 45-46 modelled a few days ago to 42-43 now. 

Tue to Thursday now showing as 38/39/37 on the Met O site for me. I can’t find any location giving a forecast 40… yet.  BBC still lagging with 34/36/36 and iPhone 34/35/34. 

Edit: in fact Reading does now have 40C on the Met auto output for Wednesday.

I’m starting to think the peak heat day may now be Thursday.

To be fair you could say the red warning should be for three days!

with an easterly drift. Sometimes I think they over doo the impact into London. For instance tomorrow at has 26C for London on the grid point.

Arpege does tend to over do temps in the West Country sometimes not sure why. 

But I think 40c somewhere between Tuesday and Thursday is now 50% imo.

And in contrast, but not worthy of its own thread, a few rural locations in Aberdeenshire recorded an air frost last night. The lowest I can see is -1.7°C. Impressive considering the date.

Here, in the rain shadow east of Dartmoor there's no sign of any rain for a couple of weeks, and it looks like all will be dust and varying amounts of heat, often excessive and for several week, if not months.

It's all really hard to take.

BTW the max yesterday was 27.7C at Writtle, which was a degree or two higher than most models went for.

On which topic could this thread be split so those of us can find info about this heat and where those of us getting on in years (and with elderly dependents) can keep up with developments/thoughts without having to read of people enjoying this (for me, I think I would enjoy it we're I younger) sad weather event?

I don't want to either be upset by the views of other or indeed upset them with mine. I just want to get through this while being informed.

So something like a 'Heatwave - how to cope, what are the prospects of relief'? Thread and a 'Heatwave, will it last'  thread.

Matty, I am, honestly, happy for you. I know you enjoy hot weather, but for me this is a test of my resilience.

There are hundreds of thousands of people like my father, or me, who will be severely tested this week.

And no commute the following morning, either, as work was just a couple of hundred yards down the road!

EDIT: I appreciate though this won't work for everyone, or even most people. Dev's situation is much more complicated than mine was!

Because we live in upland Devon and shouldn't have to think about fleeing the heat.

It's really difficult. There will be god knows how many people struggling like me this week.
