Pff. Get a large saucepan, fill it with boiling water from the kettle, pop it on a low shelf, close the door and let the humidity melt the ice. That's how I've defrosted mine for the past few years - and it's now 26 years old!

It's absolutely roasting here at work, having come across the playground just before lunch you could feel the waves of heat coming from the asphalt. It's 26C back home and I suspect a few degrees warmer here.

Now 32c here, and it is stifling in the heat, as humidity is higher today. For old people this is real heart attack weather, little sleep followed by the body working hard to cool down

Herstmonceux the form player this season it seems. Unheralded beforehand, often overlooked by selectors, but has put together a string of classy innings to secure its long term place in the squad.

I have been there many times. Full of racist Gammon. Should be a lot of pink flesh melting today

Thanks. I'll try that next time. Bound to ice up again in a few days in this heat. I think the rubber seals have worn out as it always stops working in Summer in recent years

I got it in 1999, well my parents did. and its outlived them!

The Headcorn site is a Davis Vantage Pro2+ Weather Station. Met Office ones would have to be standard exposure - a Stevenson Screen at the right height, over grass, with no obstructions nearby, etc. I do believe the MetO would assess a site before accepting it as official.

It's now reading 33.5C so I suspect it's much too high. At this rate it will be recording 38C+ today!

Having said that it's the hottest it's been in my office room so early in the day. The sun hasn't even come over to this side of the house yet and it is absolutely sweltering in here!

Headcorn Aerodrome appears to be a different site.

Temperatures look more plausible there! I still don't think it's a Met-approved site though.

The temperature graph doesn't just go off the scale, it goes off the screen! https://skylink-pro.com/skypro_scripts/linegraphs/graph-temp.php?stationid=SGKH&date=2020-08-10&hour=11&day=10&month=08&year=2020&maindir=headcorn&hours=72&TZ=0&width=800&height=400

For Heathrow I'm using

https://www.wunderground.com/dashboard/pws/IGLAFELT2/table/2020-08-10/2020-08-10/daily

As a proxy for 2 minute updates. Its a personal WX station that is both really close and has a similar temperature.

If anyone has any better suggestions I'd appreaciate hearing them.

Looks like somewhere might scrape a 34c this afternoon.

I think easily over 35c this afternoon

I don't understand what you mean by this.

Feels a lot more uncomfortable today than yesterday. Must be the humidity

Cambridge and Stansted airports both 32C on the 1.20pm METARs so there is plenty of heat north of London, unlike yesterday.

Is Wisely near Woking?

Its on my watch list today and loos to be around 33C currently.

This one is an even better proxy for Heathrow

https://www.wunderground.com/dashboard/pws/IGLAFELT2/table/2020-08-10/2020-08-10/daily

But may underestimate it by between 0 and 1C

It's currently 33.1C and rising rapidly.

Seems pretty clear of mid level convection at the moment. There is a load of cloud across Northern France but I make it at least 3 hours away from London. Expecting a bit to bubble up later as the soundings implied they would, but there is plenty of insolation to go for the time being.

With the high humidity this feels like one of those slow but sure heat builders of a day. Nothing ultra-rapid like 1 July 2015 or the Friday before last, but not one of those days like yesterday where everything leaps up mid afternoon.

Also worth noting that the convection in France, which is visibly exploding on satellite, is across the Northern Massif central / Auvergne. Typical convection locus, but if it stays there then it will spread NE towards the low countries and miss the UK. Much better than explosive convection across Aquitaine or Limousin, which would be more of a cloud issue for the UK later or tomorrow.

Yes, just east of Woking and just outside the M25. I normally keep track of it here but this site stopped updating this morning. 

http://www.weathercast.co.uk/world-weather/weather-stations/obsid/99080.html

I don't know of any other sites giving hourly updates for these stations.

There is a real core of hear now in my watch areas of 

Hounslow 

Northolt

Woking

Richmond

32-33c in this area and inline with Arome. The question is will they go higher than the 35C predicted. I think so.

1.50 METARS: Heathrow, Cambridge, Stansted all 33. Farnborough and Gatwick 32. No 34s yet.

Heathrow actually 33.8 at 2pm.

Northolt 32.5

St James's Park 32.3
