In the southern and high plains we have probed supercells and tornadoes with portable/mobile Doppler radars, and the near-supercell, clear-air boundary layer with a mobile Doppler lidar. I will give a brief review of the outstanding scientific problems related to tornadogenesis and tornado structure and an overview of some of the datasets collected recently using RaXPol, a rapid-scan, polarimetric, X-band, and mobile Doppler radar. I will describe how ongoing analyses of the data may contribute to addressing some of the outstanding issues. The datasets to be described include the El Reno tornadoes of 31.05.13, the Edmond – Carney tornado of 19.05.2013, the Norman – Shawnee tornado of 19.05.13, tornadoes near Russell, KS on 25.05.2012, the Vinson tornado of 29.05.13, the Piedmont tornado of 29.05.12, the Granite – Willow anticyclonic tornado on 18.03.2012, and a tornado-“failure” case on 30.05.13 in south-central Oklahoma. I will also discuss plans for future field operations, including the use of TWOLF – a mobile Doppler lidar.
