Joplin, Missouri
Each June, Joplin hosts the Boomtown Run, a half marathon, 5K, and children's run. The event attracts runners from across the country, and features USTA certified courses which start and end in the historic downtown area. Celebrity runners featured at the prerace banquet have included Bart Yasso, Sarah Reinerston, Suzy Favor-Hamilton, and Jeff Galloway. In 2011, due to the devastating EF5 tornado that struck Joplin on May 22, just three weeks before the run, the event was transformed in the Boomtown Run Day of Service. About 270 individuals registered for the race after the tornado struck, knowing their proceeds would benefit tornado recovery. On June 11, about 270 registered runners and volunteers turned out to help clean debris and sort donations, contributing more than 1,200 hours of service. On August 7, 2012, the Village of Silver Creek and the City of Joplin voted to have Silver Creek annexed into Joplin City limits.
Tornadoes in the United States
On May 3, 1999, a storm produced a violent tornado in the vicinity of Oklahoma City and was a part of the 1999 Oklahoma tornado outbreak, which also brought many violent storms to the states of Kansas, Arkansas, and Tennessee. In total, the storm produced 66 tornadoes over four states. The strong F5 storm took place near the town of Bridge Creek, Oklahoma, located in Grady County. During the storm, a group of students in meteorology from the University of Oklahoma had chased the storm on a Doppler on Wheels (or DOW), which scans storms while attached to a car. Doppler on Wheels data from the nearby storm revealed winds of , which was over the wind speed in the F5 classification of that time. Though the wind speed was over the F5 maximum, the tornado was not named the first ever F6 storm, as there was no F6 classification. Other scientists reviewed the DOW data taken by the students, and concluded that the estimated wind speed may have been inaccurate, but still over . Also, the wind speed recorded was taken from over above ground level. The National Weather Service also did a damage check, and found that the damage was that of an average F5 tornado.
