The warm-weather streak, which in some places has surpassed the definition of hot weather (25.1 degrees Celsius), turns chillier and unstable starting today.

It’s going to be rainy in eastern parts on Tuesday, and rainy in western parts on Wednesday.

According to weather service Foreca, a major shift is about to occur on Thursday when a strong low pressure takes hold over Scandinavia.

First, the heavy rains are to arrive in the western parts; by the evening it’s going to be raining a lot in the eastern and northern parts, too.

On Friday, the weather is likely to turn sunnier. Occasional rain showers are still possible.

The temperatures are going to shift between 15 and 20 degrees Celsius during the week.

In Lapland, the temperatures are going to sink below 10 degrees by the end of the week.
