Weather channel have got it heating up to about 25 on Monday coinciding with more fucking rain.
BBC have it doing similar but getting up to 28 on Tuesday/Wednesday
YR.NO who are usually the most conservative on temperature have it up to 31C Tuesday - Thursday. Again with bloody rain.

Stay tuned, the insane model runs carry on. Too early for a firm forecast which is why no responsible forecaster will start screaming about "heatwave from hell" but there is some spectactular eye candy. Here is the latest comment from that fella on Netweather (Man with Beard)
Right individual ECM ensemble data is out on weather.us, and it is every bit like yesterday's 00Z (it was more muted last night on the 12Zs).
Monday/Tuesday very likely to be very warm/hot in places, but the fun and games is at the end of next week.
By Thursday/Friday, there's pretty much a 50/50 split between a) members returning to normal or slightly below-normal and b) insanely hot runs never seen before in the UK, threatening the June temperature record and some maybe even the 100F mark.
Here's my craziest chart of the day: https://weather.us/model-charts/euro...628-1200z.html. Uppers of 25C on the south coast, 24C in Wales, 23C in Dublin and 22C in Northern Ireland!!!! That is really quite mad. But honestly, it wasn't hard to find a crazy chart, a good 15 or 20 out of the 51 ensemble members could have been described as mad.

ECM is the European model, the best there is based on verification stats. It runs twice a day, each run includes a high resolution operationnal run and 51 lower resolution "ensemble" runs that serve as a tool to see what trends are forming. 15 to 20 ensemble members would be a sizeable cluster that can't be dismissed too easily.

The temperatures mentionned are what is nicknamed "uppers", ground temperatures are another thing.
850 hPa level is roughly at 1.5 km, usually above the atmospheric boundary layer. ... That is why 850 hpa temperature is used to distinguish air masses and thus to locate cold and warm fronts.
Those "uppers" are extremely high for the UK, indicating a very warm airmass moving above us. What ground temperatures we will have will depend on cloud cover and how dry the ground is (which at the moment is very much a moderating influence in unbuilt areas)

It looks like Moonlight's predicted record-busting temperatures might be to the south of us: https://www.bbc.co.uk/news/world-europe-48742241
It's still forecast to be pretty hot in the UK this week though. It's overcast and muggy in the London area at the moment, with thunderstorms a possibility.

I'm watching that cell off the coast of northern France and wondering whether it will hit Essex after Kent or drift round to the east. Last weeks thunderstorm did that but we still had a spectacular lightning display from the seafront to watch. Hoping for the same tonight.Last edited by Paul S; 24-06-2019, 21:30.

There's a cold north-easterly breeze blowing across the SE at the moment. I got in from a walk a couple of hours ago and I'm still slightly chilled.
Flaming June.
