After a dry and mild dry across the country on Sunday, rain and cooler air will return by May Day.
An area of low pressure and cold front diving into western Europe will spread clouds, rain and lower temperatures across western and southern Germany on Monday.
Communities in western Germany from Cologne to Saarbrücken and Frankfurt will have to contend with rain and temperatures some 5-10 degrees C (8-16 degrees F) lower on Monday compared to Sunday.
During the afternoon, thundershowers will develop in the wake of morning rain across North Rhine-Westphalia, Rhineland-Palatinate and Saarland. Not only will residents from Trier to Freiburg have to be alert for lightning, a few heavier storms could produce hail.
In Munich, Monday morning may be the better time to visit Auer Dult than the afternoon when the rain is expected to be falling. While temperatures on Monday will be a degree or two lower than on Sunday, highs will still be close to normal for the beginning of May.
Northeastern Germany will enjoy the best weather on May Day as dry weather holds underneath some sunshine.
Residents and visitors in Berlin planning to attend the 5th Berlin Water Sports Festival in Grünau or the Children’s Festival near the Brandenburg Gate will not have to worry about carrying along an umbrella or wearing a heavy jacket.

High temperatures across northeastern Germany will be similar or slightly higher than what was seen on Sunday. A gusty wind, however, will still make it feel cool on occasion.
The low pressure system that will provide rain across western and southern Germany on Monday will be slow to exit the region. Showers and near- to below-seasonable temperatures will remain through at least midweek.
