The weather in Finland is set to change as high-pressure systems give way to incoming fronts that will bring more snowfall and milder conditions across the country. According to Tuukka Keränen, a meteorologist at the Finnish Meteorological Institute, this shift will commence within the week, starting with a smaller snow event expected around midweek, possibly on Tuesday or Wednesday. This initial snow might primarily affect western regions, with an expected accumulation of a few centimeters.

As the week progresses, a greater storm system is anticipated to arrive in Finland from the southwest by Friday, signaling a more substantial snowfall event. The new low-pressure area will first impact Southern Finland before moving northward. This shift to a pattern of snowfall suggests a departure from the recent spell of dry, sunny weather that residents have enjoyed, and it opens the door to potentially more wintry conditions as the season continues.

In summary, the upcoming weather changes indicate a return to winter conditions with snow accumulation predicted to affect various regions in Finland. Residents may need to prepare for snowy roads and colder temperatures as the high-pressure dominance wanes and low-pressure systems dominate the weather forecast.
