The weekend's continued showers and humid air conditions can be attributed to Rene, a low-pressure system which is slowly moving across the North Sea towards Sweden, according to the German Weather Service (DWD).
In north-east Germany, the clouds and rain edging in on Friday will turn into showers and thunderstorms at night with subsequent fog. North-western Germany will stay dry during the day but can also expect thunderstorms to build up later on Friday night.
On Saturday, changing cloud cover, scattered showers and periodic thunder may turn into serious storms, particularly in the western half of Germany. The coastal regions, however, as well as Schleswig-Holstein and southern Bavaria will experience less rainfall while seeing more sunshine break through.
Although it will be wet, “the temperatures, however, will remain at mostly summer-like levels,” said DWD meteorologist Andreas Friedrich.
Highs will reach 20 to 23 degrees in the North and North-east, and 24 to 27 degrees in the East and South-east. Rain and thunderstorms will continue into the night, slowly clearing up from the West into Sunday morning.
But Sunday will still be wet, with the DWD predicting continuing showers and even downpours throughout the day. In addition, temperatures will start to sink, with highs from 20 to 24 degrees in the East. The South will remain rainy and cool, with highs not managing to clear 20 degrees.
“A slight autumn feeling will settle into Germany as of Monday,” Friedrich said.
With overreaching cloudy skies, rain showers are practically a given, Friedrich said. Thunderstorms may also return, while temperatures will remain mostly under 20 degrees.
Strong, cool winds from the south west will contribute to the autumnal conditions, and will be particularly notable on the coast and in the mountains.
The clouds should stick around overnight Monday, causing Tuesday's temperatures to remain cool, with the best to be expected just 9 to 13 degrees. Beach holiday makers will enjoy the mildest temperatures, with expected highs of around 14 degrees.
Friedrich did offer a small ray of hope to counter the dreary conditions: “By the end of next week, weather forecast models are predicting a noticeable increase in temperatures. Maybe the next summer stretch will arrive just in time for the following weekend.”
