After several warm days, temperatures will cool on Sunday and into next week, says the Finnish Meteorological Institute (FMI). Meanwhile thunderstorms continue over eastern and northern Finland.

Repair crews are working on Sunday to fix power outages following bands of thunderstorms on Saturday evening and overnight. According the industry group Finnish Energy (ET) (siirryt toiseen palveluun), the number of households without electricity on Sunday has see-sawed between 1,000 and 6,000, mostly in Pirkanmaa as well as central and eastern Finland. On Saturday evening nearly 20,000 customers were without electricity.

Lightning bolts struck Finland about 16,000 times on Saturday. Yle meteorologist Matti Huutonen says that is a large number for this time of year, equivalent to nearly half of the monthly average for June.

"Trees may be knocked down"

On Sunday thundershowers are expected in eastern and northern parts of the country. They are bringing heavy rain and lightning, which may cause damage in Northern Karelia, Kainuu, Northern Savo and Northern Ostrobothnia.

"Trees may be knocked down by wind gusts," says FMI meteorologist Hannu Valta.

Western Finland will be mostly dry and sunny in the afternoon. Central and northern Lapland will shiver with a chilly northeasterly wind and temperatures around 5 degrees Celsius.

Eastern areas meanwhile may heat up to around 28 degrees as the rest of the country enjoys moderate readings of around 20.

Snow may create traffic hazard

Early next week, colder conditions, with a chance of snow in northernmost Finland on Monday afternoon or evening. Snow may accumulate enough to hamper driving conditions on Monday night in northern Lapland, especially as most drivers are using summer tyres.

Temperatures in southern and central Finland should be near 20 on Monday, and again on Tuesday in the south, while cooler air will move into central areas. Wednesday night may even bring severe frosts to central and northern parts of the country.
