Took me by surprise...

 

Although I guess I've been ignoring PA and watching SD/IA/NE like a hawk the last week so maybe I'm the only one surprised, haha.

 

Oh okay, thanks for the clarification. Based on your original post, it came across like this severe weather threat was a surprise overall.

Yeah. Me too. It's all coming across the scanner now. Sounds like it hit on US Route 40 lifted and hit again in this crowded development. They are calling additional units to the scene along with building inspectors, DelMarva Power, etc.  Hope there is no serious injury. Thanks for Tor Warning this storm. Sounds like it meant business. 

 

Edit:  additional damage being reported north of Newark.
