Has any year before had 2 distinct record breaking heatwaves?

Looks odds on now for the June record falling as well as the May.

It's terribly sad. A week of super hot and dry air will do much damage (some permanent) to vegetation and our trees.

Tuesday definitely seems to be firming up as the hottest day, with 38C on UKV and 40C on Arpege. GFS is still going for Friday as the peak though.

Here's the current reporting network - I see Brogdale is still on it, as an aside, but I do wonder considering it's not reported since March!

There was talk of thickness records earlier - the 00Z GFS has a 579dam in Sussex, which would break the 578dam record from June 2019.

If the current output comes to fruition there has to be a chance that the current Amber warnings go red. Pretty excited right now. You know when Darren is invested (even though it’s not his thing) that something historic could happen

That's my station, and it's still accepting data every 5 minutes. TBH considering these obs make their way into the MetO's modelling - I can't for the life of me see why they would want to end it!

Now can we even be certain this June heatwave (also likely record breaking) will be the peak? or could we be looking at another heatwave with the low 40s in July/August.

Well you can normally add 2c to ECM max temps. So 40c is definitely an option next week.  I'd give it a 30% chance atm.

Since Cyprus Met allow so many stations opening there there some very high temperatures outside Nicosia as before they only had 5 stations for main towns, but now so many so seeing more interesting data especially in valley areas outside Troodos.  Should do the same here as some places in the UK might had been capable reached 38-40C few times before. 

Cooler today but will start seeing the heatwave starrting tomorrow to the whole week.

Head to the beach if possible, if you're not far from one.

Guaranteed to be cooler.

DWD have recently made some changes to the ICON gribe compression and templates, although I don't think the underlying model has been changed. Therefore, there have been problems with updates on TWO in recent days, but this is from today's 06Z update.

Latest 6z GFS gives us one day of relief from the heat next Saturday, but then shows signs of it returning quickly.

Starting to get a feeling about this summer, as I've always been a believer that the general summer pattern sets in around the solstice.

Was certainly the case in 2006, 2007, 2012 and 2022.

Could we be on the cusp of a record breaking summer?
