Well, immediate DC area, according to SPC meso, we've got 3500-4000 SBCAPE to work with, if I'm reading the squiggly lines right. We had any kind of shear at all, things would be rocking around here. 

Tomorrow could be good if we can get full sun starting in the morning... shear should be quite decent

That cluster of storms in SW VA extending from roughly Albemarle to the VA/NC border sure has the derecho look. They started out somewhere west of Cinncinnati this morning, and had no issue jumping the mountains. Roanoke gusted to 58 when it came through down there

The line that just rolled through Reisterstown was the second worst storm I've ever experienced. Only the derecho in 2012 in Pittsburgh was worse. There are several trees down in my cul de sac. One fell on my roof, another in my car. It went from nothing to like a hurricane in less than a minute. 

I went up in the attic and checked and it doesn't appear to have punctured the roof, but the house shook which isn't a good sign.

Thanks. I like big storms, but this was right at the borderline of "too much".

I hear you. It’s all good until it’s right in your backyard. It was bad by me but doesn’t sound like anything near what you experienced. Happy you and your family are ok.
