I rather feel that this should be adopted as the new standard measure.

I've also pioneered the "Magnum test". I noticed on Wednesday a thick layer of water formed on the chocolate layer of the Magnum ice-cream I was eating. In fact clean water started dripping off it. 

Local PWS has 28.7C at 8.20am which is 4C higher than yesterday at the same time. I think today will have a rapid warmup but peak early before the core of the heat pushes east.

UKMet 3z has 40c in East Anglia by 1pm then cooling off thereafter, it'll be interesting to see how close to thd mark it is.

Somewhere like Tibenham is the place to watch, I suspect. 

Low 20c.

Roll tomorrow.

The temps will plateau early afternoon,then fall slightly.Yes it might just nudge 30 but  not go on up to mid 30,s

It’s amazing how quickly the temperature can drop off once the airmass changes. 

29.3C here at 9am. iPhone app says 27 now with a high of 32. Met Office says 29 now with a high of 34. BBC reckons 27 at 10am with a high of 33. I reckon we might reach 35 again. Local PWS has recorded highs of 36.4 on Wednesday and 35.6 yesterday. 

This feels like a record type of days when you are seeing 30C at 09:00.

I wasn't going to take my dog for a walk today, instead we stood on the pavement outside the house for 10 minutes - means he still gets to see a bit of the outside world, but without all that effort to walk. The pavement is shaded by the large viburnum shrubs in my front garden. It was 27 when we walked out the front door, 29 when we went back in!

EDIT: Jumped straight to 29.6 as I was typing this post!

And it's now hit 30. It'll almost certainly exceed 35 today, only the 3rd time in all the 43 years I've lived here. (In 76 it got to 31 apparently!)

9.20 on my local PWS. Even Blackbushe which usually under-reads quite a bit compared to other local stations is already at 29.3C and could hit 30 before 10am.

Currently the data is out as far as 0900Z on Wednesday, which gives a max for Tuesday of 32.5C. Yeovilton hit 32.7 that day and Westonzoyland does seem generally cooler than Yeovilton but could still have beaten Merryfield.

There's also Marnhull, which got within 0.2C (32.3) of Yeovilton on Monday, when Yeovilton was the UK's hottest.

Data is on the WOW site.

Blue skies and a slight breeze.

At 10AM it's 32.0, dew 23.8 - so not far off!

It certainly feels fresher here near the coast. Especially with the swamp cooler effect.

I can't see the temps exceeding yesterday as you suggest. Which for me is great.That and the day before were exceptional and unpleasant, dangerous even, as some of the hospitals found out. Soton being just one.

Similar here - 31.3C at 10.00am and rising fast. Locked in everywhere and north facing lounge starting point is 26.4C. My  wife is fed up with me following her around reminding her to close doors. Always got the aircon in the bedroom to fall back on though so we cope so much better than we used to. I moved into this house in September 1976 when the drought broke!
