There's a major and impressive heatwave gripping western Europe with temps close to, or breaking records.

For example, the official Paris forecast max temps over the next 10 days reads like this: 33, 39, 32, 36, 39, 30, 32, 34, 32 and 33 degrees with overnight min temps only getting down to 25 on some nights. London fares a bit better with a max of 33 by Wed and a min temp of 21 on Tue morning. Berlin, Germany is going for max temps to start reaching 35 by the weekend. But Spain takes the cake with temps in some central and southern locations reaching into the low 40's.

Here's a map from COLA showing how much warmer or cooler than normal that temps are likely to be averaged across the next 8 days:

I can't remember where I read this but Heathrow recorded 36.7, a record for July in the UK I think.

I had a meeting this arvo with a colleague in the Zurich office and he was complaining about the heat. 36 yesterday and around 33-34 expected today. They have a heatwave alert scale that was up to 4 yesterday. At level 5 you can get sent home from work.

Yep that's correct kizz.

Heathrow's 36.7C breaks the UK's all time record for highest July temp. London was still 30C with a dewpoint of 16 at 9:20pm the other evening (impressive even though it was still sunset time at this time of year).

By 10am London time the other morning, Heathrow Airport had already reached 32.5C. Still just shy of their all-time record during the 2003 European heatwaves but not bad for for over 50N latitude.

Some other interesting stats from the last few days:

* In some parts of the UK, dewpoints up to 22C combined with temps in the 30s.
* 19,500 lightning strikes detected across the UK withint 34hrs with over 15,000 of these over Scotland.
* Max reached 38.2C at Maastricht, Netherlands.
* Max reached 39.7C in Paris.
* Further severe thunderstorms possible for parts of western Europe.

Meanwhile, here's the latest official forecast for Geneva in Switzerland:

There it is for Heathrow - http://www.ogimet.com/cgi-bin/gsynres?la...ra=06&ind=03772

Click on the date and you see 32.5 at 9am! The temperature did fall back a bit later in the morning before rising in the PM. Hard to say if it could have been hotter without that late morning dip or if the maximum potential heat was mixed down regardless.

There's some good material on the DWD (German weather service) website if you can read German.

There were near-misses on the Dutch and Belgian national records yesterday with 38.2 and 38.1 respectively (a few tenths short in both cases). In general it's looking like this will be the most significant western European heatwave since 2003.

(By the way, the 32.5 at Heathrow was at 9am GMT, so 10am clock time).

Some stunning storms just kicked off across the UK. Current lightning rates of 260 strikes per minute which is decent for over there. Likely to see more good storms across Europe over the coming days.

Indeed, I was watching some webcams around London this morning for storms and the lightshow was truly spectacular. The lightning tracker was virually blank one minute then lit up like a xmas tree within a short period of time.

Here's some photos sent in to the BBC (credits provided in the pics) from the previous round of storms in the UK as well as a lightning tracker image I saved from a few hours ago. What a reward for the heat. Insurance companies estimate the hail damage bill to cars might reach 1.5 million pounds. 50,000 blacked out as well:

Amazing stats continue to emerge from the ongoing European heatwave.

Germany broke its all time heat record by getting to an impressive 40.3C at Kitzingen, Bavaria on Sunday during the ongoing European heatwave. The previous record was set in both 1983 and 2003 (tied).

Many other German towns and cities also broke their all time heat records during the weekend (records go back to 1876 in some places). Unseasonably hot weather looks set to shift into southern/eastern Europe

On a side note, unseasonal heat continues for Alaska, southwestern Canada and the northwestern US. Here's a snapshot I took of the official forecast for Fairbanks, Alaska from the US National Weather Service:
