This tornado was well-sampled by two separate mobile research radar teams, the University of Oklahoma RaXPol radar and the Center for Severe Weather Research's Doppler on Wheels. Both radars captured high temporal and spatial resolution data relatively close to the large tornado. The maximum tornado width was 2.6 miles. However, the damaging wind swath was much larger, as non-tornadic downdraftwinds extended for at least a mile south of the tornado. Given the difficulty of separating this damage from tornadic damage,the OU RaXPol radar was used to help determine the width.
