My iPhone App has just pushed the forecast temperature today to 39C.
Here are the hourly readings at Heathrow from the existing record day, Aug 10 2003.https://www.ogimet.com/cgi-bin/gsynres?ind=03772&lang=en&decoded=yes&ndays=2&ano=2003&mes=08&day=10&hora=18Times are in UTC so add an hour for BST. We want to be seeing 30C+ by the 10am point to be ahead of the game.
Do you have these for 1 July 2015 too? I seem to recall temperature rising even more quickly that morning.
Kenley registers 25.1C at 7am as the dew point falls off a cliff
Takking of falling dewpoints look out for the Heathrow dewpoint plunge phenomenon that happens often on very hot days with SSE wind. Went down to7C on 10 Aug 2003, and down I think to 9C on 1 July 2015.

Notice how it actually dropped quite significantly after reaching 34C by 10.00Z, then rose again in the afternoon.
Heathrow takes over climbing very fast now
26 °C
Already 24C at Manchester Airport at 8am.
Also 24C at Manchester University.
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 JulyHigh temp reports - suspended for now, will re-open tomorrowPotential record breaker - speculation as to where things will happen nextCurrent conditions - actual reports from where you are now unless meriting a post in Historic heat WatchConvection thread - reports of storms and their developmentModel output thread - developments over the next few days

Let's not forget as well that if anyone is either unhappy about what is happening today or wishes to gloat about that, there is also the summer moaning thread which is currently on page 2 of the default list of threads on this forum as I write.
Kew Gardens already at 26.1C at 08:00 BST compared to 22.9C yesterday
Interesting that there's showers brewing already over N. France. Could be an issue for heat seekers.
Showers over Northern France should head into Belgium (hopefully)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.
I think that it was the High Temperatures thread which DEW meant to lock as he did say in his post within various threads within this forum that it would be suspended until tomorrow, but he hasn't actually posted anything in the High Temperatures thread so far as I write and that thread wasn't locked the last time that I checked.
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.
The showers are heading NNE, so the ones over the Cherbourg Peninsula (and upstream) are heading toward SE England, but they are not really developing. There's a decent chance that they don't amount to much and the cloud is minimal/transitory.
Although having said that there's a few sferics showing up now!

This development has me slightly worried. Its day we want to channel to kill off any activity!
