President Barack Obama will deliver a high school commencement address in Joplin, Missouri, nearly a year after a killer tornado ravaged that city, the White House said Monday. Obama will deliver remarks on May 21, just one day before the first anniversary of the tornado that devastated large sections of the city of 50,000 people, cutting a path of destruction nearly 14 miles long and up to a mile wide. The tornado was classified as an EF5, packing winds up to 200 mph. The Joplin tornado killed 161 people, making it the deadliest single U.S. twister in more than 60 years, according to National Weather Service records.

Its 2,200 high school students returned to class on August 17, with a mall substituting as classrooms for many of the upperclassmen. School Superintendent C.J. Huff told CNN he's excited about the president's decision to showcase the students. The class of 2012 has been through a lot, he said, and has shown "tremendous resiliency and leadership" in the past year. The visit to Joplin is Obama's second since the tornado. He attended a memorial service a week after the disaster.
