I think the al time record is still safe.

Reckon 36C is the highest we'll see today.

Yes that's been my thinking. Wind seems to be gusting a bit more westerly here now and the temperature has fallen a couple of tenths. Maybe 45 mins before the cloud blocks the sun.

Heathrow currently only showing 34.0C for the 2pm figure but they often update after a few mins.

Just looking at the latest Arome run. It only shows a max of 29-30C for Heathrow tomorrow, which is some 6-7C lower than the Met Office forecast. High temps look to be restricted to the far south tomorrow on that run. 

Arpege also only going for 32C max tomorrow. Looks like the models have done a big about turn on the weekend!

iPhone weather app has also slashed the forecast with 34, 31, 31, 31 for London from tomorrow. Something has changed big time.

Good 

Levelled off at 34.4*C here (2:15pm).

 

Here are the current soil moisture levels - quite low in parts of the south-east. A wide range across the country.

That's a very interesting map, especially as I didn't know it existed until now.  I'm pleased to see that it confirms what I've been posting on TWO for many weeks about the local low soil moisture level in west Kent (and Surrey), which is the lowest in the country, along with coastal Norfolk, central South Coast, and south Devon areas.

34.9C here. Cloud approaching.

Maybe factoring in more instability? Can’t see whet other major change there would be at 24 hours out. Or cloud ovarhang from today?

Heathrow was 35.4 at 2pm. I have no idea why Weathercast put 34.0C in as the rounded figure.

Re above it will be interesting to see if the Met drastically revise their website forecasts downwards over the next few hours.

ECM forecast maxes this weekend (add a couple of degrees as a rule of thumb).

Saturday

See my earlier post on this. The rounded figure is the METAR which is an entirely different reading available at 50 minutes past the hour. It is replaced once the hourly Met station reading is available.

Kew Gardens now ahead of Heathrow with 35.5C

Wisley even higher at 35.6C

Thanks, I had missed that.

Kew just in the lead with 35.5C at 2pm.

The weak trough to the west has not been well forecasted. More activity than expected on that line so will influence things as the afternoon progresses

Down from 33.7 to 33.3 here, wind picking up and cloud arriving. And Heathrow is only 20 miles from here. No records happening today, other than the date one which I assume has already gone.

Some cloud overhead here now but very fragmented.

Temperature has reached 33.9C so nearly up to the 34.5C last Friday.

Jiries is going to have a meltdown over this cloud
