Brrrrr, now the cold is predicted to come here, regions around my hometown could reach -18 to -21°C tonight.

Thats almost extraterrestrial for our usual winter conditions in the region. Last time we had such temps was 1978.
In Nuremberg - much more to the south, not close to Münster - a heating plant is burning. Parts of the city are low on or have no heating. A coincidence of event and weather that will be remembered by many people down there...
No busses, trains, taxis, trucks, cars, mail, garbage collecting. Only trucks with food supplies for supermarkets drive here. Several ones bogged down yesterday and today at my location.
