Here it is March 24th and it's snowing heavily in Portland Oregon?

My son woke me up to live stream a video of heavy snow coming down in Portland Oregon. He was amazed that snow was falling this late in the year there because it hardly ever snows there even in January or February (but March?). He said at that time this morning it wasn't sticking yet but I said to be careful driving in it whether it is sticking or not because of experiences I have had. It's sort of like driving in heavy hail where you feel like you are driving on little ball bearings sliding you all over the place. But, still, snowing in Portland on March 24th?
