If not today, I'm sure 40c will be beaten in a future heatwave. The potential is clearly there, and with passing time becoming statistically more likely.
ICON 06z reassuring - am posting here as it's a nowcast really. Similar 850s to the 00z throughout the day, ever so slightly higher in mid-late afternoon, and a few 41s showing on the map in Lincs and S Yorks.
Another very warm night in the far East especially Norfolk. 23C, could even be warmer than last night and more humid.
Sunny!
34.8c

Heathrow showing 34.1C at 09 00
That is just crazy - easily going to hit 40C today somewhere

If we can be around the 37C mark by 12, I’d be very happy. If I’m being greedy a 38C would be wonderful.

All other output suggests we beat the record by about 1pm.

The weather doesn't take any notice of the models (although Arome was spookily accurate in 2019, as it had a tiny 39C circle right over Cambridge!).
34.1C at Heathrow now, and Cambridge airport also 34.

If it carries on like this yes. But it has to slow down sooner or later. Fascinating day.
Little Bursted vineyard still having a stellar morning. 33.6C at 10.15, within sight of yesterday's all time record of 34C already. It's 80m up in the downs and was 20C only 2 hours ago so that's some going.

34C now so 6C left to go to 40C soon.

The Heathrow weather station is also on grass and actually closer to the road than the runway. I think this is it.
35.6 now. Think the rate of increase has slowed somewhat.
Some very think wisps of high level cirrus. More like streaks than actual clouds (not contrails).
Quite a few 35s now
