Europe's Heatwave Breaks as Temperatures Plunge Up to 12 Degrees Celsius

Europe – A welcome respite is arriving for much of Central and Eastern Europe as a record-breaking heatwave finally begins to break. Temperatures are forecast to plummet by as much as 10 to 12 degrees Celsius below seasonal averages in some regions this week, offering relief after weeks of scorching heat.

The cooling trend is driven by a change in atmospheric circulation, with colder air masses moving south from Northern Europe. This shift is expected to bring temperatures down to below 30 degrees Celsius in countries like Hungary, Poland, and Romania, returning them to more typical seasonal levels. The most significant temperature drops are anticipated in Northern Italy, Slovenia, Croatia, Austria, the Czech Republic, Slovakia, and Poland by Thursday.

By Friday and Saturday, parts of Southern Italy, the Balkans, and Greece could experience an unusual cooling phenomenon, with temperatures falling 10 to 12 degrees Celsius below normal. Nighttime temperatures are also expected to decrease significantly, potentially reaching the low teens Celsius or even around 10 degrees Celsius in some areas, which should help alleviate the urban heat island effect.

However, the end of the heatwave does not signal a complete return to normal conditions. The collision of the retreating hot air over the Mediterranean with the incoming cold air mass is predicted to trigger severe thunderstorms and heavy rainfall across regions stretching from Italy to Romania and the Black Sea coast. Furthermore, while the rain may offer some relief from drought, the risk of wildfires remains high due to the dry conditions accumulated during the intense heatwave. Meanwhile, Spain and Portugal on the Iberian Peninsula are expected to continue experiencing heatwave conditions with temperatures around 40 degrees Celsius.
