Nowcast job tbh now. All other output has 40c

Here's the TWO heatwave tracker update.

Do you have Arome in 1hr intervals. I can only see 6h/18h etc

For once it's cooler in Leysdown - just a shame I'm in Sittingbourne today!

Once again there's a hell of an inversion at my place. 18.3C compared to 26C elsewhere.... when it gets mixed out the rise will be insane.

26.0c on the nose here at 7am following an overnight low of 23.4c.

Incredible temperature on what should be an incredible day.

Yes, lots of detail on meteologix.com

Well nobody has told Carol Kirkwood that on Breakfast. Still talking about 40/41 possibly 42, as they have been doing for a few days now.

Check out Tims PWS at Lynns Sore Bottom if you want to watch an inversion getting mixed out !

Yes, just risen from 20.6 to 21.7 in 3 minutes.

EDIT: now 22.5C 2 minutes later

I’m 24.1C now (Pett Bottom). 4C in 10 minutes.

I don’t think everything has to ‘align perfectly’ - basically the entire eastern side of England from London to the Tees could exceed 40C today. It’s not like we’re talking about the usual heatwave where such extreme temperatures are usually very localised. Even if one station cops an isolated shower, there are still countless other stations that won’t. 

An impressive rise!

Still under the inversion in Leysdown, just about to hit 20C now. (It goes to show that even with an inversion, things are still heating up relatively quickly). Neighbouring stations are showing 27C.

Nice!

Now, does the official record require 9(am) to 9(am), or will 9pm to 9am suffice? I guess we'll soon see!

Indeed, the 00z runs of some models (Arome, GFS etc.) have trended towards the ECM with a faster lifting of the trough and reduced warm advection during the afternoon.

I still think we'll just about exceed 40C today, but it doesn't look as certain or widespread as I thought yesterday.

The Met Office website says for its extremes "Lowest minimum temperature - (2100 on the previous day to 0900 on the date shown)", but that doesn't explicitly say whether that period counts as the record. 

It is either Kenley or Emley depending on how it is worked out.  I am hoping it is Emley as it wound be quite comical for the record to go from Brighton (you can imagine being sat comfortably on Brighton beach all night) to a windswept Pennine Moor (where you can't)

It would be good if the 300m high TV mast on Emley Moor had temp stations on its structure, to see what they read and where the optimum heat spot was.
