Yeah, I eyeballed half an inch at 6:30 am well after precip exited east of the bay. Temp had risen back up to 36. Heavily compacted like it was almost a layer of ice when I scraped my car.
So it could have been close to an inch, max. LWX spotter reports had Ashburn at 0.5” as well.
I got the lower end of the stick here, but happy that we pulled a rabbit out of a hat in a bad pattern early on.
