It was found that the TDWR, with much higher spatial and temporal resolution, was superior to the WSR-88D in resolving the evolution of small-scale storm features. The TCS was always more easily discernable in the TDWR velocity data. The TDWR velocity couplet associated with the TVS tracked very close to the tornado damage path, while the KTLX data was much less accurate at times. The TDWR was also able to resolve one or more surges on the rear-flank downdraft (RFD) that descended into the mesocyclone region and eventually was tied to the development of intense low-level convergence and the TCS. The KTLX WSR-88D did resolve an RFD surge, but it was difficult to track and observe in great detail because of the radar’s lower temporal and spatial resolution. The TDWR data was also found to at times be difficult to interpret because of its ability to resolve detailed structures and its tendency to undergo velocity folding. Nevertheless, the TDWR was shown to have advantages over the WSR-88D in observing important small-scale storm features.
