Going by ARPEGE's 12z, the Atlantic westerlies won't have made it past the West Country as of 2 pm, and will still be west of London as of 7 pm.

The only real inhibiting factor is the length of fetch across the Channel, which I expect is why the southeast is expected to be several degrees hotter than the Central South; they've only got a short fetch across the southernmost North Sea to peg back the temps. The wind looks relatively light too, though still a notable feature; gusts to near 20 mph for the most part.

 

It's 6th in Europe's highest.

Also Mexico which is central Mexico smashed the French one today @52C, Myanmar in Southeast Asia 47.2C.

As for Chad its one of the cooler Saharan records. 51.3C in Algeria or or 55C Tunisia.

The rest of your selection are largely tropical.

For me Canada holds the most impressive a 45C recorded at almost 50n latitude.

Mexico does indeed hold a higher record; it is considered N America, not C America. Myanmar is, similarly, like SW China, more continental in type and not included in the SE Asia selection. You missed the fact that Zambia is a highland area; that would have been a good point. But none of this detracts from the point that it is impressive that France's record has fallen by > 1.5 C in a non-usual-record month.

Despite it taking up half of central America you correct that Mexico is considered part of North America, however Myanmar is considered southeast asia.  It is part of mainland southeast asia along side countries like Thailand & Malaysia.

Probably a good bet that tomorrow will be the warmest day of 2019 given 34-35c may be reached.
Hoping for 29c here, Met Office says 28c for LBA (up from 23c earlier in the week as per the natural upwards trend with the automated forecasts) and it is normally 1-1.5c warmer here in a sheltered garden with UHI effect. Their forecasts also go for 30c for Leeds, 31c for Doncaster.
30c here at nearly 200m would be very unusual but seems just outside of grasp. 2015 saw 30.7c which is the highest of recent times.

But it is only 14.5c now not a great starting point to obtain heat. 

Gonna be some turnaround! 15C here in Essex at 10pm, falling in the brisk N.Ely breeze. and just 50 miles or so from France. Amazing. Will it be the biggest change in two consecutive days maxima (20.5C today). Probably not but still will be a remarkable one day wonder.

Amazing is not an overstatement.

MetO automated still going for 6 hours of 30+ tomorrow here in South Cambs and Alex Deakin hinting at possibly 34-35.

It will be interesting to see how it pans out.

Wind is from SW here but still managed to get misty low cloud dragging over the moors and 11.3C this evening (after a warmish 20.1C earlier)

Met Office now going for 31C in Leeds, BBC going for 30.

The temperature now really shouldn’t matter at all. The Met temperature map shows the heat peaking here at 7pm so later than usual.

15.6c and still falling....I'm waiting. 

We have lift off. 

A rise from 15.6c to 16.0c since the last post.

Right, Im firing up the VP2 for the first time in months.

Arome ensembles have a 50% chance of 35C being breached in London tommorow and a 30% chance for most of Kent.

The AROME ensembles also have a crazy minmax range.

32C is the minimax, 39C is the maximax.

OK here is the AROME max temp ensemble distribution in full

32  x

33  xxx

34

35  xx

36  xx

37

38  xx

39

40  x

And yes it was actually 40C, not 39C. I found two pixels of it on ensemble 12.

I should point out the ARPEGE ensembles (despite being more out of date and having more ensembles) are a complete anticlimax.

Minimax: 31C

Maximax: 32C

17.7 c at 12.15 am with 84% h giving a dp of 15 c. I have a fan turned on and it's actually doing a good job in keeping me cool for a change but will have to turn it off before going to bed and that's when it's going to hit me.

If I had to guess I would go for 34.5C. Upper range of most of the high res models after disregarding some of the crazier Arome ensembles.

Just had a quick skeg on one of the model outputs, 24 c 850's right over Kent at 5 pm Saturday . . . then 10 c at the same level exactly 24 hours later.

The mind boggles.
