Just travelled back up from Paris- left it at 38c and here in Calais it’s 17c

Incredible

Leeds Bradford Airport coldest spot in Europe today at 12 C...laughable

Closer to the record june England cold (7 degrees away) than warm (on the south coast, 12 degrees away)

6.8C on the summit of Mont Blanc today. All time record:

Quite chilly this evening with a fresh force 5 NE'ly wind and variable amounts of stratus blowing hurriedly in from the ENE with a temperature of 16.2c.

Its going to be a shock as soon as that hot SE'ly kicks in on Saturday.

16.2c chilly?!!!    I’d welcome such a toasty temp!  It’s 12.9c here!    

Yes, I think Saturday will be a welcome shock to some!

I must have missed it!  

Ah, Saturday then!

Well, we've now had in June, the wettest drought in history, and right now, we're having the coldest heatwave in history.

Roll on July for some (hopefully) standard summer weather with temps around a pleasant 21c and blue skies.

Well so far it would appear Plymouth pinched top hot spot officially at 24.5C

Still there is the data from the other none published stations yet to come.

I know Gosport Fleetlands for example had an automated hourly 24.4C so after human analysis that could be warmer - it has happened a few times.

 

Note: 3 amateur gosport stations all had higher than 24.4C today and it was over 25C here in nearby Portsmouth.

Spot on Moomin. If Richard was in Oxfordshire on holiday form Aberdeen, he' have good reason to complain

This is not like the easterlies you have in mind as the wind at the 1000 - 900 hPa is very strong and directly from a very large body of cold water. It doesn't allow for vertical mixing either upwards or downwards.

I have seen something similar even in the Greek islands; T850 > 25C, yet surface temps in the mid to high 20s (same as the SSTs). The locals call it natural air con and they love it. 

If this is truly the case... then it implies the forecasters at the Met Office are inadequately educated on such things. I can't see why else their video forecast maximums are widely 2-5*C above the numerical modelling; they have the same orientation of the high and resulting winds.

So I'm not sure there can actually be zero vertical mixing. Just less of it than in a weaker, drier easterly. It seems some must have managed to happen today, despite the short heated ground fetch enforced by the low cloud belt, to permit 23-25*C in the far south and southwest today in what were unusually windy conditions for late June (most of the local small-talk this afternoon has begun with how weird it feels).

Tomorrow brings the greatest test of the Met Office forecasting so far in this spell of weather, assuming the low cloud dissipates or clears away overnight (and I'm not 100% sure about that as it was supposed to be mostly absent by now, but there's loads of it persisting!).

If tomorrow proves sunny yet only maxes out in the low-mid 20s across central and western parts of England and most of Wales, then it will be time to start wondering what on Earth those who modified the raw model data so far upward were thinking of.

...although I must admit, I've already thought that a little bit today with respect to the central-third of England, but have put that down to another classic case of underestimating the stubbornness of British low cloud formations .

Took far longer than forecast for the cloud to clear - all morning in fact. Then max of 19.1C so the wait for the first 20C of summer goes on.

Only four times since 1945 it's taken until July and two of those in the past 12 years which says it all.

I'm amazed you got to 19C, the high here was 11.8C despite sunny spells after about 3pm.
This evening it's calm and clear, a chilly 8C

So am I.

The highest temperature for today across my three local stations was 18.3°C which was recorded at Edinburgh Gogarbank.

That isn't exactly spectacular for this time of the year but with the wind still coming in from off the North Sea, I would have expected Aberdeen to have been a bit cooler than here in Edinburgh as a result.

If this is truly the case... then it implies the forecasters at the Met Office are inadequately educated on such things. I can't see why else their video forecast maximums are widely 2-5*C above the numerical modelling; they have the same orientation of the high and resulting winds.

I don't think it's a case of the MetO forecasters being inadequately educated; there has been a lot of confusion with their forecasts across different platforms with some very poor video graphics on their twitter feed. For example, last weekend they had a video graphic showing temps of 30-34C (almost 10C above the raw model values) for Wed-Fri this week and even on Monday they were showing 29C for London on both Tue and Wed.

As I said at the time, these forecasts were both wrong and unprofessional, but I have no idea who produces them and why they differ from their text forecasts on their website.

Anyway, max temps should be around 3C higher than raw model values for the next 3 days in the south, but again nothing like those silly video graphics.

Very good chance of 32-34C north of London on Sat.

 

7C here

This time last week, we were thinking about uncomfortable nights, heat, humidity and possible major thunderstorms for this week. It has been a pretty big downgrade, it has to be said.

This was Alex Deakin last Friday, shows the Met Office were really taking note of the possibilities.

I have made this point time and again over the years. It is all very well spending a lot of money developing excellent numerical models, however if you then have issues disseminating information in a consistent and timely fashion the benefits are lost completely. The reasons why this happens are relatively clear to me but the discussion belongs in the UIA and not the weather forum.

You know it's topsy-turvy when St Catherine's Point (referred toby Stormchaser yesterday) is confirmed as the warmest place in Britain at 24.2C. FFS, a hilltop site sticking out into a still cold English Channel

---

Germany and Poland have new June temp records of 38.6 and 38.2 C respectively, sites close to the border.

I was amused by the journalistic hyperbole 'Records smashed' - the old June record from 1947 was 38.5!

Looks like Porthmadog was the warmest yesterday with 24.7c. Wouldn't be surprised if it was again today and tomorrow

7C here

This time last week, we were thinking about uncomfortable nights, heat, humidity and possible major thunderstorms for this week. It has been a pretty big downgrade, it has to be said.

Whereas if you'd been looking at the ensemble data, it's not been a downgrade at all. The ensembles never did buy into the really high temperatures being shown by the odd rogue run and they were showing an utterly unremarkable spell at the surface, with astonishingly high 850s at the same time.

The models - thus far - have handled this brilliantly. Once they'd picked up on the boundary layer being so heavily modified they stuck with it, even as various places were Tweeting about heatwaves and so on. It's a very unusual setup, of course, and it's a good test to see whether the GFS and ECM, both of which now boast far more vertical layers than they did a few years back - can handle the effects of what's in reality a very thin layer of modified air.

So far they've done well. It really is quite surreal seeing a strong gusty wind, thick cloud and a surface temperature of 14C (in my case), knowing that a few thousand feet up it's 18C and humid with it.

Apologies  Only clicked on the regional tab on the MetO site
