I dont rate UkV it always over does temps in heatwaves.  Arpege is normally much more accurate.

I'm actually surprised the models are disagreeing so much given that the physics here is more simple than it usually is. High potential temperature with minimal mixing.

There was a similar event of insane date records in Western Canada as I recall in (I think) 2021

This being the UK it will likely take 27 years and cost £8 billion.

It's looking like a remarkable spell on the way, GFS has continued to move towards UKV/MetO and now has several days of 27 here, the Saturday rain which it's been consistently showing has been downgraded and, I suspect, the MetO forecast of full sunshine will be the one that "wins". 

I'm still very puzzled as to why the models are showing such heat here considering the onshore breeze that's forecast to pick up over the weekend, the MetO for example having 31C with 17mph easterlies (from a sea which is still only 13C). 

The only other thing worth commenting on is just how unremarkable people seem to find such heat these days. We will perhaps see a couple of date records fall, an exceptional spell (just 12C above average here!), yet people seem to just take it for granted.

When I was a kid the magic number was 27c (81f), and that was quite rare (apart from 76)
