Although the middle of January was not so cold, the end of that month and the beginning of February had many days with snowfalls till Saturday 7/2, when the amount of snow finally reached 50cm here in the coastline! In the mainland the snow is much more! Here are some photos from neighborhood.
The temperature is negative all day long, but because of sunny weather the snow melts in sunshine and froze again after sunset so big icicles form.
The temperatures at night get down to -15oC, so the sea and the lakes have frost. Even a small waterfall close to my house has frost!

If the cold weather will continue, is not sure since the graphs show a temperature raise for Arendal...

There have been severe snowfalls in Oslo, too causing many problems like flight delays. Many photos from the snowfalls in Norway's capital can be found here:
