A pleasant maximum temperature of around 20 degrees is expected in many places. In variable sunny-cloudy weather, only one or two showers affecting a small area may develop.
At night, starlit and moderately or thinly cloudy areas alternate. Compared to past dawns, the sunrise will be mild.

The average of the characteristic temperature:
friday morning 3,
Friday afternoon 17,
Saturday morning will be around 6 degrees.

The most likely sequel:

• There is a prospect of further warming over the weekend, by Sunday the air will heat up to over 20 degrees everywhere, and in some places over 25 degrees in the southern part of the country. Mostly sunny and rain-free weather is likely, but with cumulus clouds, which are likely to be scattered, mainly on Saturday and in the northern part of the country.
• On Monday and Tuesday, sunny and partly cloudy, summer weather is likely with lots of sunshine and no precipitation. On Monday, the wind from the SE will revive in most of the western part of the country, and it may even get stronger, while on Tuesday strong air movement is likely in the eastern part of the country as well.
• On Wednesday, the first of May, summer temperatures and strong SE winds are expected, but an air mass with a higher moisture content may arrive. There is a prospect of more powerful cumulus clouds and scattered showers and thunderstorms in the afternoon and early evening.
