Since the upload of my raw footage, the NWS storm surveys has confirmed that twin tornadoes affected the Elgin, IL area. The stronger one of these was a 100mph EF-1 which is clearly seen in my video. The second EF-0 was to the right (when looking E/NE) and was unfortunately hidden behind trees from my vantage point.
The first part of this video is brightness-corrected and zoomed-in video of the main tornado seen in my raw footage video. The second part of the video is the full chase timelapse of this storm (footage sped up 8x).

Lightning information provided by Vaisala's National Lightning Detection Network (NLDN) through weather.us/lightning. Note that I only use this information to roughly estimate stroke intensity and distance, the data may be prone to error on my end and my work is not, and should not be considered to be, a formal evaluation of the NLDN's performance.
Thanks to Tom A. Warner and other lightning physicists and researchers who have helped me understand lightning processes explained in my videos. Tom has created a great resource for individuals interested in learning how lightning works.
