Spring-like conditions which have led to temperatures of around 10 degrees in many areas, will be chased out across the north and east by the high pressure system 'Gabriela,' which will bring temperatures seldom more than five degrees.
A powerful easterly wind will make it feel as cold as minus 20 in some areas, the DWD said, while the northern, eastern parts of the country can expect icy roads.
A rainy weather system will stretch from the northwest to the south and east on Monday, while it will remain dry with some sunshine from Western Pomerania to Saxony and south of the Main River.
Temperatures on Monday will be around three degrees in the northeast and up to 13 degrees in the southwest.
Monday night will see precipitation moving further to the south and west though, and snow should be expected northeast of the Elbe River and in the Mittelgebirge region. Lowest temperatures are expected to be four degrees on the Rhine River and minus seven degrees on the Oder and Neiße Rivers.
Tuesday will see rain or snow in the north and west while in the east and southeast the clouds will break up, with temperatures between minus two and 11 degrees.
On Wednesday rain and snow showers will be isolated, with temperatures between zero in the northeast and up to 11 degrees in the southwest.
