Grey skies and wet conditions are expected to dominate the Alpine regions especially, where heavy showers are expected all week, with 60 to 90 litres of rain per square metre forecast to fall by Tuesday.
The DWD has issued storm warnings for the next two days – until Tuesday morning - in the southern states of Bavaria and Baden-Württemberg. The grey weather is expected to continue after that, though it will get milder towards the end of the week, and more summery conditions could finally break out next weekend.
But the outlook on Monday is particularly bleak, with constant rain expected in eastern Germany, and constant rain forecast in mountainous areas. Temperatures will hover between 13 and 17 degrees Celsius. Only western Germany, where the rain may hold off, has a chance of seeing 20 degrees.
The rain will then move westwards on Tuesday, though it will stay cloudy all over the country. The DWD believes the cloud cover could begin to break up on Wednesday.
