Arpege suggesting we might just scrape 30C today, maybe Yeovilton will be the spot. That would be 16 days of 30C. 

GFS more bullish for 30-31C widely across the south.

Certainly plenty of sun at the moment although the satellite suggest quite a mass of contrails and cirrus sneaking in from the SW.

29.2 at Heathrow, maybe a 30C on the way

So many 29s but not an official 30c yet.

Apparently the official max for August 12 has been revised to 33.9C with a manual reading from Westonzoyland in Somerset.

No readings from Brogdale in the last couple of days yet.

There has been a few breaks in that cloud at times and for a while around lunchtime, it had looked as the Sun might break through yet again and had it done so, I would no doubt have been taking about our heatwave continuing for a fourth day.

Unlike in other recent days though, the cloud has been a lot more resilient and it's now very dull and overcast as I write without even any hints of brightness.

That has had an impact on our temperatures because although it's still warm, the fact that there's now too much cloud around means that it's not as hot today as it has been recently with the temperatures here in Edinburgh rising no higher than around 23°C.

That is too low for there to be any chance of the heatwave continuing even once the 18z raw SYNOP/BUFR data confirms our actual maximum temperature later on and because of that, I can now safely that the heatwave here in Edinburgh is now officially over although the warm spell still goes on.

In the end, this was a three day heatwave here but as I write, the temperature here in Edinburgh has now dropped back slight to around 21°C.

What's interesting though is that as far as Edinburgh is concerned, it was an official heatwave only at Gogarbank, but not at Swanston. In a way, you could argue for Swanston to be more deserving of having a heatwave as that particular station did after all, see it's first 30+°C maximum since 19 July 2022 and possibly even its hottest day on record during this spell whereas Gogarbank didn't quite even manage to achieve its hottest day of the year in that same spell. Yet, Swanston met the heatwave criteria for only two consecutive days with Gogarbank meeting that same criteria for three successive days, and that's why it was Gogarbank which actually had that official heatwave, and not Swanston.

However, I guess that it's statistics like that which can often make our weather more interesting even if the weather itself is boring and uninteresting.

Not sure if you got higher after that, but 30.1c was exactly the same here as our high for the day. 

Our 9th 30c day of the summer so far.

St James's park and Teddington both have 30c so 16 days 

My 9th day over 30 as well now, we get high temps later in the day here being in a valley, and wind direction plays a big part, so for example, the temp is now 29.6c having dropped to 28.5c just an hour ago. I live on the north side of a very big hill.

I'm pleased to report the heatwave is now over here - the NE'ly has arrived, as forecast, and the hot air of earlier (reaching 27.8) is now a much more pleasant 21.1 - and it shouldn't get too much warmer than that for at least the next 5 days.

Well congrats, given your preference, it's still a healthy 24.8c here, dead calm and feeling pretty good. I went for a walk about 3:30pm today when it was 30c and actually felt ok, I must be getting used to this summer now. Will need to be when we move back to Oz even in the foothills of the Vic mountains it is 30c+ for weeks on end in the summer.

30.2 at Heathrow, Wisley and St James’s Park. 

and 30.1 at Yeovilton which was my (and UKV’s) predicted hotspot. 

Looks like Southampton and Cavendish both recorded 30.4c , Writtle 30.3c.

I suppose this might fit here for now, rather than start a premature thread ...

The Times quoting Ian Cameron reports that the last Scottish snowpatch disappeared on Aug 6th this year. It was possible to pick it up (yes, it had become that small) and photograph it before putting it back and watching it melt at 1300hrs.

West was definitely best for heat yesterday, 27.4 at Porthmadog and 27.3 at Chivenor. Highest in the southeast was a mere 23.1 at Thorney Island. 

Today’s temperatures look fairly unexceptional considering the 850s are in the high teens. 

Well Fulham in unbroken sunshine has now shot up to 23 degrees should easily make 25 by mid afternoon 

Nuneaton ensembles show today 13 and 15 tomorrow so likely high 20s then big drop to 20c as per graph show 5c uppers. 

What cause not so high temps over SE despite sunny today ? 

Most of the forecast I can see are predicting highs of low to mid 20s for tomorrow. Likewise with t2m model data.

Will see if the forecast or graph are very wrong with the 850's temps v undercook forecast temps.  Yesterday the graph was correct with lower uppers and 20-21c maxes despite the forecast going for full sun and 26C.

It seems that the forecasts for yesterday (and modelled t2m values) were on the ball.

Down to 20c in the house this morning. Think that is the coolest for several months. It's been constantly 22c or above all Summer and much of Spring which I have never experienced before.
