Southern and southwestern regions will remain overcast and rainy on Saturday, with even some snow expected above 800 metres in altitude, the DWD said in a statement.
Milder weather is expected in the north, where it will be partly cloudy with some sunshine peeking through after several days of rain.
Highs will range between 6 and 11 degrees Celsius, dropping to a chilly -5 and 2 degrees overnight as the sky clears.
Though some fog and cloud cover can be expected on Sunday morning, it will quickly clear to reveal a dry and sunny day, the DWD said.
Temperatures will also rise to a springlike 7 to 13 degrees, with the warmest temperatures expected in the typically pleasant Rhine River Valley region.
Though the meteorological spring started March 1, according to astronomical calculations the first day of the season is Monday. Fortunately the weather will likely play along, the DWD said. Most regions can expect dry and sunny conditions with highs between 8 and 14 degrees.
