Recap of April 27-28 tornado outbreak

AP Photo, Tuscaloosa, AL
A tidal wave of information is available on the web and in the media surrounding what has become the deadliest tornado outbreak since the Great Depression (surpassing even the 1974 Super Outbreak).  There are so many sources and information, especially with regards to numbers, that it is nearly impossible to keep up, or even to know who or what is right.  In that vein, I have re-printed below a news article from the horse's mouth - NOAA.  Though it was released just yesterday afternoon, there are already a couple pieces of information that are outdated. I have updated those if I have a reputable source (updates in red). This is being published at 1pm Saturday, April 30.
