I saw this when I did my rounds over the SPC page, it's the best looking severe bow echo of 2012 so far by the looks of it. It's a solid, well defined arrow that is moving crazy fast which is a big red flag! The damage reports are quite something, worth a read. Reports of entire roofs being ripped off buildings and homes, boats that are 18 feet long being tossed onto roadways, sheds damaged, major structure damage to some buildings, and a 500 gallon bin thrown 1000 feet away!!!! I think some gusts of wind could be around 100 MPH with widespread 80 MPH winds for sure. Quite the disaster unfolding down there but just a note I wish I could experience a severe storm like sometime.

[CrazyC83]

How will it do after crossing the mountains? That is the question, since there are millions of people on the other side...especially if this hits the DC metro head-on...

Just about ten to twenty miles to my south tonight. Lots of lightning that way...little bit of rain here, but not much more. Looks like tomorrow will be SO much better here...

" AT THIS TIME...IT APPEARS THE MOST LIKELY AREA TO EXPERIENCE DAMAGING WINDS WILL INCLUDE PITTSBURGH...PHILADELPHIA AND WASHINGTON D.C." SPC's outlook for tomorrow.

Glad they were south of me. Just concerned for my SIL and BIL driving back to the Pittsburgh area tonight. They are in Fredericksburg and heading into the meat of this system. I know they wont stop for anything.

I live in Lewis Center OH. This was by far one of the scariest storms I have been thru. There is lots of damage to the Central Ohio area. The largest wind gust I have heard reported on the news so far is 82mph and that was in Gahanna. We have lots of trees down, roofs off buildings, a garage totally destroyed by fire, semis overturned on the freeways.

This link shows several pictures of the damage here: http://www.10tv.com/content/slideshows/ ... l?slide=20

Hopefully the next time something like this happens I will NOT be in my car

[Zanthe]

Anyone notice that Baltimore/Washington is calling this a Particularly Dangerous Situation in a Special Weather Statement?

[CrazyC83]

Yeah, both watches should have been PDS Severe IMO.

[CrazyC83]

Over 1 million customers - likely many more - without power. Could be 2 to 3 million in the end.
