As a Frederick denizen, it's amazing what a difference 50 miles has made this summer. I got a co-worker near Upper Marlboro that sends me pictures of mushrooms in his yard, and I send him pictures of my brown yard.
Just emptied the CoCoRaHS rain gauge on my deck here in Ballenger Creek (Frederick, MD). 4.05" since midnight. My Acurite Atlas rain gauge came up with 3.89" so far.
I got a mix of pea to marble sized hail just a little east of you. Made quite a racket with the wind blowing it into windows on west side of house. Got 0.56" in 10 minutes with that storm.
