From minute 1:49, it clearly shows a large Shelf Cloud with a rotating Wall Cloud developing aloft (which was probably on the Southeast trailing edge of the Severe Thunderstorm) with protrusions that were likely Funnel Clouds or Tornadoes trying to develop. Hard to tell if that was an actual Twister (Tornado) around minute 2:20 but since it was on the trailing edge of the storm, it is possible. You should have seen the Wall Cloud I encountered at the end of February of 2017 while driving through Houston under a widespread Tornado Warning. I was rerouted by GPS onto the Sam Houston Tollway due to heavy traffic on my way to Alice, Texas to deliver at 2017 Ford Raptor and the Wall Cloud was only 500 yards or so South Southwest of me and appeared to be well over a mile wide. Having worked for the National Weather Service for almost 33 years, I was trained to spot these types of weather phenomena and I do my best to avoid them. Needless to say, I pulled into the passing lane and gunned that Raptor to steer clear of the Wall Cloud and any Tornadoes that came with it. On my way back from Alice, Texas, there were many reports of multiple touchdowns in and around Houston with lots of damage.
