Widespread max heat today Ross-on-Wye,  Benson and Northolt all 33.4c

Met Office app says  34c for Leeds tomorrow. Really?  We will see.  But that's alarming and potentially in the top 5 ever. 

If I take the MetO automated forecast, then at least another 6 days above heatwave threashold here, with Thurs the "coolest" at 27c.   Only Friday currently showing as above 30c though - when I'll be at the Worcester Beer Festival 😃 

33.4C is the highest max I have seen today, at three sites: Ross-on-Wye, Benson and Northolt. Another two (Heathrow and Brize Norton) hit 33.3C, so certainly some widespread heat!

The Met Office are predicting a similar temperature for tomorrow as well, but I reckon that it might be slightly hotter than that tomorrow which might be enough to make that our hottest day of the year so far.

In addition to that, Thursday isn't forecast to be quite as hot but the Met Office are still going for a maximum of around 25°C even on that day which will be enough for an official heatwave to be actually recorded here if that comes off.

I quite agree. I'd like to see him back.  🙂🙂

Interesting to see it matches my max exactly, well the 33.3c anyway. As much as a VP2 isn't professional, it seems pretty accurate given our proximity to Benson at least. I'm sure the daytime FARS and nothing other than grass below it to radiate heat helps of course.

If Leeds predicted 34C then here 35C and 36-37C to the SE as Brian posted it this morning a 37C is shown on the map.  Need a proper sunrise to sunset without cloud hindrance to deliver those temps.  Good luck to it tomorrow.

The main concentration of heat tomorrow will be in the North and East. Cooler down South, relatively. 

Most of the prolongation of the heat from Friday onwards seems to be concentrated in the South West and central South though. 

This heatwave are very weird one and for sure Welsh border and the far west will take the crown again tomorrow again so can’t see further north and east get it to beat them. Uppers here tomorrow 17 to 18 so around 33.

looking through the latest GEFS, seems very unlikely 40 will be achieved this summer.  So it will be 3 years since 2022.  once again a case of the european heat dome never really making it across the channel.  We should be grateful for that though. 

I posted earlier in the thread about how this is possible from 2 sources I am aware of and showed the base figures for 1995

The MetO Daily Diary gives the daily extreme max for the UK  in textual form (not as a data table)

https://digital.nmla.metoffice.gov.uk/collection_86058de1-8d55-4bc5-8305-5698d0bd7e13/

 and the Met Office Hadley data repository can give 5km (among others) daily maxes for 1931-2024 in .nc format where you could do what you propose on both a national and location basis

https://data.ceda.ac.uk/badc/ukmo-hadobs/data/insitu/MOHC/HadOBS/HadUK-Grid/v1.3.1.ceda/5km/tasmax/day/v20250415 

You would need plenty of spare time and some software assistance to get from either of these to what you are looking for though (!)

It just proves that very warm uppers doesn't always equate to hot surface temperatures every time. Had today turn out to be a full sun day, then 35 C somewhere in Kent would probably be possible.

Thanks. One for a rainy day (if there ever is one again).

Day 2 of Heatwave threshold reached in Edinburgh

28.2 C yesterday and already 25 C here at 1100

I'd love to have our first official heatwave. Come on Thursday you can do it!!

This phantom heatwave is the most worst one and this morning lot of complaints from

the southern posters this morning due to clouds around. Fraught with danger as the the cloud boundary just south of Birmingham hope not to reach here. The 00Z ensembles offer better clear HP with temps to 30C here with more sunshine so hope you get much needed higher temps at the weekend.  Was 19C this morning to now 28C with hazy skies. 

Which means that the heatwave threshold temperature has already been reached for another day for your location.

After a misty then cloudy start the sun is out here now and it’s currently 23°C.

I don’t take notice with threshold temps is the condition of the skies matter most as August 2022 was the last time with gin clear skies non stop with low 30s. 

That’s fine, it just means that the forecast heatwave in your area looks et to materialise (as long as tomorrow also reaches the threshold). It doesn’t need to be completely sunny to be a heatwave, just hot.

Nottingham,  Watnall 30.5c 

The 15th 30c day of the year. 

Looks like the East Midlands will be the hot spot today.

Only today so far sunny than last 3 days.  Shocking reports from south posters said 19 to 20? Jesus that very low despite uppers very high. 

I wouldn't describe it as shocking. It feels rather pleasant after yesterday. But yes the forecast over egged the sun and high temps for today.

Our local station now showing 31.7c.  

A real difference from the south - just 23.8C at my local station but the cloud is breaking up.

15th day of 30C for the UK in 2025.

Indeed, still stuck at 19 C under gloomy overcast skies here at Folkestone and actually is feeling quite clammy and chilly for it. Quite remarkable given the 20 C uppers very close by to here. Hopefully I'll have better luck with seeing the sun tomorrow and should still be very warm despite less warm uppers so I'll be able to break out the garden chair once again - at least before the return of the north easterlies bring daytime temperatures down to near normal values for mid-August by the weekend, but likely to be still dry and bright.
