Friday will remain soggy, especially in the south and east where scattered showers were expected through the day. The north could also fall foul to a few, while the west should stay largely dry with spots of sunshine, national weather service the DWD said.
During the night temperatures will drop down to as low as 7C in some places, while inland areas should stick around 13C. Most of the country should be clear but it might rain around the Alps.
Saturday for most will start with widespread fog or cloudy skies. For central hilly areas and along the foothills of the Alps this will develop into thunder clouds, but everywhere else should clear up. Really hot weather won't arrive yet though as temperatures will remain between 18C and 23C along the coast and between 21C and 26C inland.
The electric humidity of the day will lift into a clear, crisp Saturday night with lows of between 13C and 7C and fog in some places.
Clouds will mark the start of Sunday, especially for the north which will see a little rain. Most of the country should stay dry though. Uneventful highs of 17C to 22C for the north are to be expected while in the south, it could be as warm as 27C.
But Monday will roar in with proper summer. In the south temperatures are expected to climb over an exotic 32C. Elsewhere will touch 30C, making for a sticky day in the office. By the evening though, the weather could break briefly, making way for a cooler night.
As the week progresses, temperatures could, Die Welt reported on Friday, get up to 39C thanks to warm air coming from Africa. Meteorologists are dubbing this the “Sahara heat hammer,” Dominik Jung from wetter.net told the paper.
