Do you have these for 1 July 2015 too? I seem to recall temperature rising even more quickly that morning.

Notice how it actually dropped quite significantly after reaching 34C by 10.00Z, then rose again in the afternoon.

Heathrow now 26.5 at 0700Z (8am).

That’s 3.5C ahead of 2003 (7.50 reading) and 0.5C ahead of 2015.

It's all very exciting, but there's a danger of getting too many threads so that no-one can find anything. I agree that today's weather is likely to spawn an extraordinary number of posts so useful to have them all in one thread. May I recommend the following protocol:

Historic Heat watch - actual reports from anywhere of temps today 25th July

High temp reports  - suspended for now, will re-open tomorrow

Potential record breaker - speculation as to where things will happen next

Current conditions - actual reports from where you are now unless meriting a post in Historic heat Watch

Convection thread  - reports of storms and their development

Model output thread - developments over the next few days

The north of Edinburgh, usually always missing out on snow events which occur not just within the rest of Scotland or the UK, but also within the rest of Edinburgh.

Heathrow always sets the pace on days like this. I reckon it’ll stay in the lead until early afternoon before somewhere else takes over.

Tips for hotspots today:

- London City airport

- Heathrow / Northolt

- St James’s Park

- Faversham

- Mildenhall / Lakenheath / Sandton Downham

Probably not Charlwood or RHS Wisley today.

Such a shame about Gravesend. This is a classic Gravesend Broadness day.

Interesting that there's showers brewing already over N. France. Could be an issue for heat seekers.

Showers and associated cloud over NW France does seem to be heading towards the SE corner of the UK, though a long way off at the moment. Needs watching though!!

Potential record breaker thread has been locked.

As a result of that, I'm guessing that he has probably locked the potential record breaker thread by mistake instead of the high temperatures thread.

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!

Although having said that there's a few sferics showing up now!

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.

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

Yo yo yo. 148-3 to the 3 to the 6 to the 9, representing the ABQ, what up, biatch?
