There was a massive heat wave (Saharan air) in Eastern Europe a few days ago... Ruse, Bulgaria recorded 43.5C.
Temperature reached 45.3C in Cordoba, Spain today (completely different heat wave though).
The exceptionally high readings likely sprung from a shot of searing-hot air that broke away from the western Sahara at the start of the week.
The most intense, far-reaching heat happened Tuesday, when 100-degree heat spread in a continuous swathe over northern Bulgaria, southern and eastern Romania, Moldova, reaching well into Ukraine.
Among the highest temperatures was that reached at Ruse, Bulgaria, where 110 degrees F was registered. Highs of 109 degrees were set in Podgorica, Montenegro, and Bacau, Romania. These readings are near all-time historical highs. [/QUOTE]

I think the 45.3C recorded in Cordoba today is the highest temperature in Europe this year.
