It is caused by stalled circulation. The currently prevailing Eastern European blockade is turning into a high-over-low blockade. The affected region is on the leading edge of a persistent trough, which is cut off due to ridging over northern Europe and nestles in.

It will run side by side with the traditional physics-based Integrated Forecasting System (IFS).

SW, W and central Europe will melt by WED with temperatures of 35 to 42 °C, at least according to the ICON, which admittedly represents the upper end of what is possible. In terms of temperatures at 850 hPa, we are in the top 0.5 % percentile, close to record levels.

🌡️ “I can’t stand this heat anymore! Summer just started, and it already feels endless. Is there a weather regime change coming up?”

Well… it’s complicated. 🧵

Bref coup de chaud mardi&mercredi associé a une dépression "pompe a chaleur" au large du Portugal #PlumeDeChaleur, puis probable mise en place d'un très puissant #DomeDeChaleur (fort anticyclone) pour la fin du moins de Juin avec persistance de chaleur extrême (Sud 🇫🇷).

🌍🌐 What if we could relive past extreme weather events - only this time in a colder or warmer world? That’s exactly what scientists working on the Climate Change Adaptation Digital Twin (Climate DT) of the EU-funded DestinE initiative are doing. Find out more ➡️ destine.ecmwf.int/news/storyli...

If we choose not to act,
Or fail to adapt,
Then suffer we will.
