A NEW PERIOD of dry and warm weather is about to start in Finland, forecasts the Finnish Meteorological Institute (FMI).
The high-pressure front across the eastern border looks set to stay in place for the foreseeable future, continuing to push warm air from Siberia to Finland. It is possible, though, that a small low-pressure front moves north-east across the country later this week, delivering showers to central parts of the country.
“It looks like the [rains will occur] in roughly the same areas that saw the three storms in June,” Jari Tuovinen, a meteorologist at FMI, commented to STT.
“In southern and eastern parts of the country, the rainfall will nevertheless be very limited.”
Outside of some local showers in areas along the eastern border, hardly any rain has fallen in Finland in July.
“July has started very warm, as did June. There’s been no rain pretty much anywhere. It looks like a new period of aridity and heat is about to start,” gauged Tuovinen. “Seeing how trendy it’s to talk about waves in other contexts, let’s say that another wave of aridity is coming to Finland. The current week looks fairly bad in that regard at this moment.”
He added that the duration of the heatwave will depend on when the high-pressure front moves or dissolves. It presently appears that neither is imminent, meaning the front will continue defining the weather in Central and Eastern Europe.
If the front were to move west of the Nordics, it would mean air would flow to Finland not from Siberia but from the Arctic Sea.
“This will determine whether it’ll be 30 or 15–20 degrees warm,” said Tuovinen.
June brought not only record-breaking temperatures, but also unusual aridity to vast areas of Finland.
“Some measurement stations definitely had heavy rains. In Salo, for example, it rained 67 millimetres, which is 15 millimetres more than the average for June,” told Tuovinen. “In the big picture, there were considerably more areas that got about a half of the usual rainfall than those that got or exceeded the typical amount.”
