10:07 PM: As of the top of the hour, no snow sightings in West Seattle – mostly overcast, upper 30s. But as the photos show, the clouds that have dropped snow on points north of the city were visible from here before nightfall:
Both the National Weather Service (see this tweet) and weather analyst Cliff Mass (see his update) say the convergence zone is “sliding south.” The Winter Weather Advisory remains in effect until 6 am, and we’ll be on watch through the night.
10:41 PM: Thanks for the comments, tweets, and texts – snow sightings in north West Seattle.
11:07 PM: More reports – it’s continuing to spread southward.
11:38 PM: Car tops are now frosted up here over Lincoln Park.
12:35 AM: Still very light, and no accumulation beyond the car dusting.
4 AM: Some areas got notable snow – like Alki (Robert Spears‘ photo, above, taken just before 1 am, and this one from Pelicans south of Alki Point) –
… and others did not, like here in Upper Fauntleroy, where the car-top dusting is where it stopped. We’ll be launching morning coverage soon; for starters, Seattle Public Schools has announced a 2-hour delay (school changes are here).
