On Tuesday morning, residents of southern and central Finland are greeted with a thick blanket of fog, particularly from Uusimaa towards Kymenlaakso, and there are fog banks over Pirkanmaa. According to meteorologist Ilkka Alanko from Foreca, the fog is anticipated to dissipate as the day progresses, although exact timings remain uncertain, posing a risk of slippery road conditions due to the icy fog.

In contrast, southwestern Finland is experiencing clearer weather, with sunny conditions expected to develop after the fog lifts in many areas of southern and central Finland. The recent monthly forecast highlights that while northern regions may see above-average precipitation this week, Tuesday's showers are expected to be minimal, with some snowfall also anticipated in the morning hours across northern Finland.

As the week moves on, precipitation is forecasted to increase, with rain and sleet expected later in the week as indicated in the monthly forecast. Specifically, conditions should remain dry and pleasant across the country on Wednesday, before the arrival of wetter weather stretching onwards towards the end of the week. This shift signals an important change in the weather patterns affecting Finland.
