Just before 5:40 am today we had two of the loudest possible thunderclaps imaginable. I was actually looking through my camera viewfinder, to take a picture of the falling snow, when there was a flash, then only a split-second later, a bomb-like boom that shook the house back and forth and caused car alarms to go off on our street. Then a couple of minutes later, it happened again. Did you hear them? Did they wake you up? Tell us about it in the comments to this post.
