24c here as of 08:30

Already up to 25.5C at 08:30 on my weather station. Extraordinary heat for so early in the day, and ahead of where it was at this time on 1 July 2015. Got a very good feeling about today!

Me too, if the cloud can stay away. 

Now 25.4C in the city centre.

26c at 8.45 gone up 2c in half an hour!

---

28C at Headcorn. Forgot about Headcorn, it’s close to the centre of the heat today.

Will be a shame if those showers give us a pall of mid level cloud right at the peak of the day. There are more of them than in the high res models.

Indeed. Met Office hinting at the chance for some thunderstorms from 15:00 onwards for Manchester. As much as I'd want one, hopefully they hang on until evening, so we can see the record go first!

32C in a couple of spots in Northern France now.

---

The 08:50 Obs are going to be interesting. App is now sowing 28C.

To remain on schedule we need to ave achieved 26.7C. We were already very close at the last check point.

---

Temp now 26c

---

The returns over Normandy suggest that thunderstorms are likely in the SE at some point early afternoon which may spoil the heat lovers' party.

The latest UKV has them arriving between 14:00 and 15:00 UTC

9am Heathrow reading is a bonkers 28.8C. Smashing it so far.

That’s 2C above 2003 and nearly half a degree above 2015, which had a big blip in late morning.

9am temperature here 22.6c (garden is heavily shaded in the morning).
25.1c at Leeds University.

28.8C at Heathrow @ 08:50

This is currently 2.1C ahead of 26.7C observed at the same time in 2003

---

Can anyone clarify whether there are two readings at Heathrow, one at xx.50 and one at xx.00? I noticed the hourly reading has sometimes changed after a few minutes on Weathercast so perhaps it puts in the 8.50 reading and then updates to the 9am one? If that is so then it increased by 1 whole degree between 6.50 and 7.00!

I’m tracking the storms over NW France with interest and concern.

If they remain smallish single cells then they’ll dissipate and we only need worry about home grown stuff and a bit of cirrus. If they grown in scale and become multicellular they could give us a mid afternoon pall of mid level muck, 2015-style. So far they’re hanging in there and not dissipating but not exploding either.

---

The more I look at those 2015 readings the more exceptional that record looks. After reaching 34C+ by 11am it dipped to 31C and you’d think it was game over but then it surged back up to 36C within a couple of hours during the afternoon.

09.20 and we’re at +26.1c

I am hoping that, they might start drifting NW west once they get to the channel. I am nervous as well.

Radar seems to suggest light rain for the most part - may in fact be Virga / evaporating before hitting the ground. There’s nothing cataclysmic looking yet.

---

Those showers over France haven't developed into storms at the moment, so cloud footprint not as extensive as it could be if they did.
