What was NIAB in 2019?
38.2C IIRC. So 0.5 below the BG.
Edit: no, that was the airport. NIAB was 38.1C. Apply the same correction and we get 40.5.
Ha, love the first comments
"Source?" From some inquiring mind concerned with challenging the scientific status quo
Everyone else: "Urr, they are the met office, they are the source"
Shame that Gringley On The Hill didn't top the list.
Not for this thread really, but suffice to say that there is no room for opinion when it comes to clear evidence.

Does anyone know if the 850 temps have been higher than yesterday's record at Cambourne? Could they have reached 25C?

22.6C at Herstmonceaux was the highest at 12z today, but the plume went a long way north! Nothing approaching 25C though.
Exactly. Looks like a nice place with a great name!

Sorry to the folks at Coningsby but your name is somewhat boring.
Shame the nearby Bawtry or Doncaster or anywhere not on the hill at 10masl or so didn't have an official station.
Was this wrong then Darren?

I'm not sure that's the case - the Met Office seem to get the instantaneous figures much earlier than us - they quoted higher figures than the hourly ones for Kew and St James's Park, among others - they never showed a 40C on the hour but the Met tweeted about them going over 40.
If that is the case, they will therefore know in advance, everything which goes into any raw SYNOP/BUFR code that is produced before that is publicly released on the usual outlets (such as ogimet.com) at the specified times.
Does this therefore mean that it is the Met Office who are responsible for producing that raw SYNOP/BUFR code, or that they at least play a role in producing that code?
Another point here is that you are never going to know what the actual maximum temperature was before the actual end of the particular 24 hour time frame for which that applies, so even the Met Office aren't going to know that before then (which I had thought that was the reason why the raw SYNOP codes which give those maximum temperatures were usually always produced at 18z every evening).
A max of 34 yesterday puts this heatwave for this area well down the list. Quite unusual as we normally catch the hot weather.
The widespreadedness (is that a word) of the extreme heat today is astonishing.
I may have missed it but I think there were 850's yesterday of 25.2c a new record. Was that beaten today?
Max in Wales today seems to be 36.2C at Hawarden, so beating the previous record but lower than yesterday unless there is an official site on the north coast which benefitted enough from the southerly earlier on.
Just imagine how hot it must have been in Gringley in the Valley.
interesting it’s near historical met hotspot Bawtry.
