The storm will likely head southeast during the day, the DWD said, saying that up to 20 centimetres of snow could cover the north.
Overnight Bavaria's Oberfranken region was also pounded by more snow, creating treacherous road conditions that kept street crews out in full force, authorities said.
Slow moving traffic and felled trees filled many rest stops beyond capacity by midnight, police there said.
Saxony also struggled to recover from heavy snow non Wednesday, with traffic jams several kilometres long reported on motorways into the evening. Some 76 accidents with three injuries were registered in the area.
Meanwhile huge snow drifts closed motorways near Wildenthal, Johanngeorgenstadt, Eibenstock, Schönheide and Stützengrün, a situation likely to create major jams on side streets, police said.
The weather might have been a problem for commuters, but children in some regions woke up to good news. School was cancelled in the entire state of Schleswig-Holstein, parts of Lower Saxony, and many parts of Rhineland-Palatinate because buses couldn't get through the snow.
