The wind shift is near Paris and temperature is stalling, probably earlier than London? Btw now it's 0.4°C warmer at Orly than at Heathrow at 2 pm BST.  Anyway, congrats for joining the 40°C club! To be fair Heathrow is essentially a microclimate due to the urban heat island effect. Are there any other areas in the UK where it has hit 40°C Bound to be when the official figures all come in - even here in Sheffield, it has reached 38.4°C. |

Cambridge, Lincoln etc are forecast 41-42c. It's 37c in Newcastle, ridiculous! Heathrow usually records cooler high temps than Kew Gardens, and is comparable to Northolt and Wisley, so the microclimate argument is bogus. |

Just for fun I put my thermometer in a shady tree area of the Communal area outside my flat (which means it actually reads lower than official readings), and it was on 99°F. On my walk around it really didn't feel too hot to me. A nice pleasant day.

Heathrow is not the warmest weather station in the area. Kew Gardens is reguarly warmer. Shielded PWS in the surrounding area (such as Whitton) are also regularly warmer than Heathrow. |

Kew Gardens is warmer on average. One day doesn't mean much with local variations. It also doesn't help that the Met Office closed down several weather stations that were all warmer than Heathrow, in various parts of London (Camden Square, LWC, Greenwich Park, Olympic Park, Kensington Gardens to name a few). |

Temperatures now falling quickly across Leeds. Western half of the city down to 35/36C, eastern half still 39/40C.
Right on schedule.

Still 40C here in York. Even Topcliffe is pushing 40C!
There's a good chance Yorkshire could have the hottest night and day on record for the UK by the end of the day! Crazy really.

Somewhere in northern England now holds the national heat record, these are crazy times we're living in.

5 locations reached 40c so far today (this is excluding any automated stations that we won't know about until tomorrow).

I am loving hearing about these heat records in the UK. Totally epic!  It brings back memories of the PNW heat dome last year and I had a couple of nice beach days at the time. |
