Hope this is ok to open, as we head towards a potentially short but potent spell of hot weather.

It currently looks like areas just sw of the Wash can expect the highest temps (35/36c?).

What is not clear is:-

• how quick the heat moves away on Saturday


• Can we beat the all time June record (35.6c)?


• will it go bang?


• can the heat return from the south east next week?

Shall we use this thread for short range model runs, plus our predictions and obs?

Mods - feel free to change as required 

This morning so far Arpege 36c, ICON 32c, GFS 31c , GEM 34c for Friday 

Wow, quite a large range for something just a couple of days away. 

UKV in at 35C.

Yep, the models are struggling with this one. June record is just about still on though.

Good thread - Thanks and well done.

Friday night into Saturday is looking extremely warm. Minima for London area are 20C on Arpege, 22C GFS, 19C ICON.

The record for June looks to be 22.7C at Ventnor Park in 1976. That one looks safe. Still, a pretty stuffy night. Interesting to see if we get a "tropical night" anywhere.

GFS seems to be showing much higher temperatures for Saturday than for Friday (for London), which goes against all other model output I have seen. Is there an error in this output or am i missing something?

Yes, and your old local station at Swanston in the south of Edinburgh currently has the honour of sharing that title for Edinburgh's highest temperature with Edinburgh Gogarbank with 20.8°C being the highest temperature so far at both of those stations.

Edinbugh Airport has had a temperature of 21°C, but that temperature is only recorded and then reported to the nearest 1°C which raises the possibility that the temperature at the airport might not necessarily have been as high as it was at those two other stations.

28c in St James's park today making it the hottest day of the year. 

Arpege also has 30c tmrw and 30c on the south coast Saturday 

A PWS near me recorded a maximum of 28.8*C this afternoon.  That's plenty hot enough for me!

Arpege still going for 35c tmrw . The other models 32/33c ish. Which you can normally add 2c . I think the June record is definitely on. Depends on cloud cover.

Might be lucky and reach 28c...
