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.

---

07:00 and it's already 27.3°C. Phenomenal!

Now to try and get some sleep after my night shift. 🤣

---

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

---

Up to 28C in 3 places at 7am: Tawscoed (was already 28 at 6.30), Pembrey sands and Biggin Hill.

---

UKV 3z has 43c around Goole and 39-40c here. Heat reducing by 3-4pm, bit earlier on Met Office App.
UKV maybe a couple of degrees too high in places yesterday though.

---

So the overnight minima were not all that impressive in most places due to a dip in the early part of the night. The low in many places was around 1am before the rise started but that was enough to take a lot of them below the old record. Looks like we will still end up with a new record somewhere though.

As for the max, who knows? I think we can make it to 39, but 40C feels like a lot to ask as everything would have to align perfectly and we know it rarely does on days like this!

---

Already 23C here, couple of degrees ahead of this time yesterday

---

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

---

Big tout on beeb for highest maxes today in East Midlands ...We shall see..

---

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. 

---

Over 28c already out there and no cloud… Today is the day…

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.

---

25.9C Emley Moor
25.8C Kenley
24.5C Aberporth
24.4C St Catherine’s Point
24.2C Leek

All are 9pm to 9am lows that are above the previous record.

Also 25.8C in Jersey.

---

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.
