This was the single deadliest tornado in U.S. history since modern record-keeping began in 1950. Rated EF-5 on the Enhanced Fujita scale, this mile-wide tornado was the largest and most powerful type, and it traveled 22 miles on the ground.NOAA details on the Joplin "Super Twister"

Are We Storm Ready?
Today on MPR and KARE11 we begin a new series on tornado readiness in the Twin Cities.
In light of the deadly and devastating tornadoes in Joplin and Tuscaloosa last year, and with rapidly increasing tornado frequency in Minnesota we wondered just how well prepared is the Twin Cities metro for a major tornado?
MPR and KARE 11 news mangers asked me and KARE11's Belinda Jensen to come up with a scenario...a "tornado simulation" that is meteorologically accurate that would strike the hear of the Twin Cities metro.
The result? A devastating EF3 to EF4 tornado with winds of 150-200 mph that follows a typical Minnesota southwest to northeast tornado track from the southwest Minneapolis suburbs of Shakopee, Eden Prairie and Edina right into downtown Minneapolis.
The series looks at how shopping centers, schools, senior care facilities, hospitals, traffic jammed freeways and stadiums would deal with an approaching tornado.
It also looks at how we process severe weather information in a tornado situation, and who's responsible for your safety in various public buildings and stadiums.
Look for the series for reports from MPR reporters Curtis Gilbert and Paul Tosto, and KARE 11's Jay Olstad the next two days.
This is some pretty illuminating stuff. We like to think we are ready in Minnesota for just about anything, but are we really "Storm Ready?"
