Same here and something change afoot from what we expecting very humid but it turn out dry heat with temperatures steady rise slowly as it normally does on dry heat days to now 30C.  If was humid like yesterday then it would shoot quickly.

GFS 06z says it should be raining now, but its totally clear!

And people wonder why it’s not trusted!

33.7C.

Just driven ten miles in the countryside with 32C to 34C showing in car

Tibenham airfield is 17 miles north of here. That's promising because here, the rate of increase is becoming quite marked - 2C in 30 minutes to reach 34.5C. I thought my sensor might be acting up but an 'above lawn' shade temperature check at 2m with a clinical mercury thermometer is reading 35.1C.

Yesterday it all levelled off at around 1pm.

Here's a TWO Twitter exclusive hot off the press! Meteo France Arpege 06z (on the website we make available 00z and 12z updates but not 06z) temperature forecasts for this afternoon. Max values of 36C are shown. pic.twitter.com/q6H67C6Nxa

Well that is already wrong as it shows only 23C across the south coast when they're already widely  25-27C

July record is 37.3C, all-time record is 38.6C.

32.2C here now and been sunny for few hours now, just a bit hazy that now making things hotter as it been 30C for nearly 2 hours.

Variable hazy thin cloud here. The temperature has definitely levelled off now compared with yesterday. Currently 32.5C having dropped back from 33C whereas it was at 34C at 1pm yesterday.

Brian has tweeted the Arpege 6z temperatures for today and they show a slight cool down across the far SE from early afternoon. That appears to be underway.

Unlike yesterday at 1pm, still rising here. 35.6C I wonder how Tibenham is doing? (just on Sky News as 34.1C)

[edit] Spoke too soon - signs of it levelling off here now at around 35.4C

Those charts also show a big cooldown over East Anglia around 2pm, presumably due to modelled storms. Those don't seem to have triggered yet - radar is totally clear in that area - so maybe a bit more solar heating could nudge up to a new July record?

Today is now the 3rd hottest day since 1900, only 2003 and 1932 to go (need another 1.3C to get them both)

Exciting

Don't know about EA but down here I wonder whether it might be a reflection of the mixing that is underway as the HP retreats eastwards. The wind across Kent is now starting to move out of an easterly quadrant and turning more and more to the ssw.

Tibenham currently at 34.3c and has been for about ten minutes.

Date record is 34.4C (Margate and Cambridge Botanic Gardens) 1933.

It seems that it peaked here at 12.15 when it hit 33.4c

So So close!!  Just dropped back to 34.2c.

Where are you getting live readings?

Cloud has really bubbled up here in London in the last 20 mins or so.

Just noticed that Wattisham, about 9 miles SW of here, was reporting 32.1C at noon when I had 32.9C.

After a bit of levelling off, I've now got 35.8C but without a 'proper' station local and current to compare it to yet, that needs a large pinch of salt. It should be within a degree, though.

Pretty impressive given model resolutions etc. https://www.weatheronline.co.uk/weather/maps/current?LANG=en&CONT=euro&LAND=UK&REGION=0003&SORT=2&UD=0&INT=24&TYP=temperatur&ART=kartealle&RUBRIK=akt&DATE=--&CEL=C&SI=mph 

Here we go!!

Date record equalled:  34.4 just reached at Tibenham!!
