Why did it happen?
The main cause of the outbreak of 2003 was that there was a persistent warm air mass over the central United States. That was coupled with a strong jet stream, strong upper level winds, atmospheric instablity, and an intense low-pressure system. Because of this, there were nearly 2,500 reports of severe weather in one week.The Pierce City, Missouri Tornado
The most notable tornado of the week was the one that hit in Pierce City, Missouri, maybe 40 miles west-southwest of Springfield. According to reports, nearly all of the buildings in the town were damaged, destroyed, or liable to collapse. A National Guard armory where some people took shelter was flattened. Two people were killed and six were missing. The Pierce City tornado was a F-3 on the Fujita scale.Later on in the week...
The record-breaking week of severe weather hit the central United States relentlessly. On May 8, a tornado hit in Moore, Oklahoma. No one was killed but 100 were injured. At Warr Acres, Oklahoma on May 10, an 80-year-old man was killed when he hit his head on a door jamb while running for safety. The house was spared, but the man died the next day.
