I managed to catch the Kennedale/Arlington tornado forming just west of 287 & S of I-20. Started the video camera and moments later the funnel appeared. Tracked it for about 5mins there, then followed it up across I-20 and to Green Oaks where is dissipated. I put full 5min the video on youtube, but the best part is around the 2:00 mark.
Thanks for reading!
