A warm air mass due to move in over Finland could see a welcome, albeit fleeting return to warmer summer weather, according to Yle meteorologist Matti Huutonen.
Huutonen said Tuesday that while daytime temperatures won’t reach the highs seen during the past summer, they could rise above 20 degrees Celsius in the south on Wednesday. Huutonen said that the warmth could extend into central Finland on Thursday and Friday.
However in northern parts of the country, highs will range from 10 to 15 degrees.
Finland owes the warm spell to the influence of hurricane Helene, which has been rampaging across the North Atlantic as well as a low-pressure zone which is wafting warm air currents from central and Eastern Europe.
Uncommon at this time of year
Huutonen noted that fog and gloomy clouds are part and parcel of autumn and on days when the fog does not dissipate, temperatures will remain in the teens.
However he said that statistically, daytime highs around 20 degrees are a rare autumn treat in Finland. Temperatures that rise above 25 degrees Celsius are an even rarer event at this time of year. The last time Finland saw such highs during autumn was on 17 September 1947, when a measuring station in Tampere recorded 25.2 degrees.
The warmer weather will be short-lived however and conditions will be rainy and cool on Saturday. Huutonen said that there are signs that temperatures will be considerably chillier next week than over the next three days.
When that time comes, daytime highs in southern Finland will be no higher than 10 degrees Celsius while the north will see temperatures drop to around five degrees.
