I'm in the zip code 20910 just south of the 495 beltway and north of the DC northern apex, in Silver Spring.
Just measured about 4.75" averaged across a few spots in the yard and on a snowboard surface.
I was out shoveling from 8am til now. Went from SN+, to SN- with a bit of ice and frozen pellet drizzle (?) to back to moderate snow with bigger flakes in the last 15 minutes.
Hope I can pull 6" out of the first part then another 1-2" later.
