Finland's summer heat to be temporarily interrupted by cold front, with heatwave possible by week's end

Finland enjoyed warm, sunny weather for Midsummer, with some northern areas experiencing nearly tropical nights. However, this warmth is set to recede as a cold front sweeps across the country on Sunday, according to meteorologist Eveliina Tuovinen of the Finnish Meteorological Institute.

The weather will turn on Sunday as a cold front moves across Finland.

Northern Lapland has already seen significant rainfall, nearly 50 millimeters in the past 24 hours. As the cold front moves through, temperatures in the south and central parts of Finland will drop slightly, accompanied by cloudy skies and the possibility of rain and thunderstorms. The weather is expected to clear up by Sunday evening.

There have been quite a few thunderstorms during the night. In the south, this materialized as a strong thunderstorm passing over Tampere.

Temperatures will remain close to summer heat levels, with the northern parts of Uusimaa potentially reaching heat levels. While Saturday saw highs of 24.5 degrees Celsius in Helsinki, Sunday's forecast includes warnings of severe thunderstorms, particularly in the Kainuu, North Ostrobothnia, and Lapland regions. Thunderstorms also occurred overnight in areas like Tampere and Kajaani.

But it's possible the cloud won't grow high enough to start thundering. But in any case, hot, warm, and very unstable air is above us too.

Looking ahead, the beginning of the week will be mostly dry and sunny in the south and central regions, with temperatures around 20 degrees Celsius. However, the weather is expected to become more unstable by Wednesday, with rain likely in the southern and central parts, and possibly Uusimaa. By the end of the week, there's a chance for a return to hotter weather, with a potential heatwave developing.

The predictability of the forecast for the end of the week is poor, but towards the end of the week, a heatwave might begin, really warming up properly.
