The biggest temperature shock is prepared for us mainly between 21.-26. August, firstly, with last big heatwave in Europe, then with Arctic blast from northwest.
Around 21. August, temperature in Europe will be really high, up to +44°C in SE Spain, +38°C in France, Germany, Italy and East Central Europe and +42°C in Balkan.

During fifth August pentade (21.-25.8.) will be moving over Atlantic ex-tropical storm or ex-hurricane Jospehine, respectively, where will be merged with extratropical Icelandic cyclone and together will cause massive Arctic blast over parts of Atlantic and after 25. August in quickly in Europe, too.
In Scotland, Iceland, Norway, Sweden and Finland, frosts are possible in air masses with T850hPa 0/-5°C, very fresh air will bring autumn minimum temperatures only +3/8°C, in parts of Mediterranean only +10°C around 26.-27. August. It will be the first early autumn cold blast in Europe, with first possible ground frost in densely populated areas.
We will monitor the situation and will bring the news about this topic during the weekend and the next week.
