Significant Damaging Wind and Tornadoes - May 8th, 2009

National Weather Service, Springfield, MO

 

Event Summary

Severe thunderstorms in the form of a derecho (A widespread, long-lived thunderstorm induced wind storm) caused widespread wind damage across the Missouri Ozarks and southeast Kansas Friday Morning, May 8th. This derecho produced widespread winds of 60-90 mph across a large portion of southeast Kansas and southwest Missouri, and continued to produce these winds well to the east into Illinois and Kentucky.  In addition to the powerful winds, numerous tornadoes were also spawned within the line of thunderstorms, several of which were strong tornadoes in the EF-2 and EF-3 range with winds of up to 165 mph. Finally, very heavy rainfall with these storms resulted in significant flash flooding across much of the region. 

Not only were significant winds observed along the leading edge of this powerful line of thunderstorms, but behind it as well.  The nature of the thunderstorms allowed the complex to create its own extremely strong area of low pressure.  The pressure was so low behind the thunderstorms that air had to rush in from behind to equalize the pressure difference.  This persistent rush of air, primarily from the northwest, was so strong that winds were estimated to reach as high as 90 mph, and winds of 60 mph or greater lasted as long as 20 to 30 minutes.  The strong winds both at the leading edge of the line and well behind it caused significant damage, uprooting, snapping, or damaging thousands of trees, destroying or damaging barns and other outbuildings, moving mobile homes from their foundations, and even causing some structural damage to well built homes.
