A series of systems brought heavy precipitation to southern Oregon.  Initially the heavy snows were limited to higher altitudes...but a colder air mass moved in towards the end of the event and snow fell in areas that rarely see snow...such as the southwest Oregon valley floors.  At one point after the storm, 25000 people were without power.  Several highways around Crater Lake were closed for a week due to heavy snow and fallen trees blocking the roads.
