Interesting radar imagery

The clouds were thin, with breaks in them, this morning. The sun was shining through the breaks and there was occasional light snow falling. It was an unusual-looking sky. Timo Nousiainen from the university sent an email pointing us to the radar imagery. Look at the unusual pattern. What could cause these structures? Note that the winds were light from the north and the clouds were relatively shallow with very dry air aloft.
