PEOPLE in the Finnish capital region should brace for varying weather this week.
Jari Tuovinen, an on-duty meteorologist at the Finnish Meteorological Institute (FMI), told Helsingin Sanomat on Sunday that the capital region will experience temperatures that bounce around the freezing point and rains that come and go roughly every other day.
On Tuesday, temperatures in the region are forecast to stay above the freezing point until northerly winds pick up in the evening, dragging temperatures five to ten degrees below the freezing point by Wednesday. By tomorrow evening, the region will welcome its next “massive” wet weather system, added Tuovinen.
“The rain will start as pure snow, but the winds will turn to southerly and south-westerly and make the weather warmer. By Thursday morning, half of the rains will be pure water,” he said to the newspaper.
On Thursday, he added, temperatures in coastal areas could climb as high as +5–6°C and scattered showers are expected in parts of Southern Finland. The winds will turn to a northerly breeze on Friday, bringing temperatures back below the freezing point.
Tuovinen explained that the changes are attributable to a central low-pressure system hovering over the Norwegian Sea and North Atlantic. The system is dispatching humid fronts toward Finland.
“This close to Christmas, the entire country should have sub-zero temperatures also in daytime. However, because the massive low-pressure system is sending partial low-pressure fronts, you’ll typically get this kind of accordion-like weather for five to seven days. That means we’re talking about a typical large-scale weather situation.”
With temperatures bouncing around the freezing point, the road conditions will be hazardous for motorists and pedestrians alike. The 5–15 centimetres of snow that fell on the capital region at the start of the week will condense under the weight of water.
“You should definitely put on cleated shoes right now especially in the capital region. It’s also important to make sure roads are sanded,” said Tuovinen.
