The most extensive precip is south of the city, but some strong bands to the north. Light snow last hour at Sea Tac in the southern band, and Port Angeles and Friday Harbor in the northern features. Too warm for snow at sea level--Sea Tac is at 452 feet. In heavy precip, the snow level can descend to the surface. Hard to get snow to the surface in strong onshore flow...even cold flow like this..unless you have sufficiently intense precipitation.
The mountains are just getting pummeled.
