The line of severe thunderstorms came through a while ago, but it's still raining heavily here as of 1am. It awakened me (and our dog!) with its lightning, thunder, high winds, and very heavy rain. This really came out of nowhere as I thought the inclement weather was done for the evening before I went to bed.

Wind-driven rain pounding on the roof and window woke me up in Silver Spring a few minutes ago. All seems much calmer now.

I didn't hear thunder, at least while I was fully conscious. It's possible that thunder woke me up.

The intense T-storms passing through Arlington woke us up about 12:45 AM, so I wanted to check for any warnings.

We had storms? Darn it, I miss all the exciting stuff. Never heard a thing. :(

I missed the rain. Is there a link for a radar loop of last nights storm so that I can see how intense the storm was?

VA Hospital Center is several blocks from where I grew up - I was a candy-striper there a couple of summers. I understand why they had to close George Mason between Washington and 15th because there's a little section of woods right there. Lots of trees for a T-storm to pull up... maybe a bit suprised they didn't close that intersection completely because there's a park with more trees on the other side of George Mason.

We live in Upper Marlboro, MD right off of Crain Hwy (Rt. 301) in the Marlton subdivision. Around 1:00 a.m. this morning (November 17th), we were suddenly awaken with what sounded like a freight train heading towards our house. The sound got louder, the wind was intense, and the rain turned to hail. It came so quickly that we were unsure what was going on. We live in the path of planes landing and taking off of Andrews Airforce Base so we didn't know if it was a plane or wind but it was something so loud that we were nearly disoriented to the point that we didn't know where to go. After a few short minutes, it was all over. When we looked outside we had lost a large tree that was pulled out by the roots on the side of our house. Our neighbor next door lost a tree that fell onto one of their cars. Their patio table on the back porch was tossed off and landed near the front yard. Our neighbor across the street had a large tree that had been snapped about 4 feet from the trunk and it was lying across the front of her yard. When the sun rose, we discovered that a tree had fallen across our fence in the back yard as well. Does anyone know who we can contact to find out if a tornado touched down on our street? If so, please send an email to There are no other trees down on the other three streets in our section or on the main highway leading into our section of the subdivision. We are surrounded by woods on one side and a community golf course on another. Something definitely came through to cause that much damage.

Heavy thunderstorm around 12:30--12:45 am near Baileys Crossroads. Little damage except that a lot of the leaves blew down.
